WISMEC Sinuous P80 TC Kit Preview

Intro: Wismec Brand company has just released a flagship kit named Wismec Sinuous P80 Kit.

It is no exaggeration to say that Wismec is one of the biggest e-cigs company in this industry. Most of their products gives me a solemn feeling with their huge sizes. For this time, Wismec released the Sinuous P80 Kit with a really compact size.

The Wismec Sinuous P80 Kit comes in five colors totally, black, red-black, blue-black, bronze-black and silver-black. The one I got is in blue-black.

It is packed in a rectangular paper box. When you open the box cover, the first item you see is the Sinuous P80 mod. You might be wondering why there is only a mod inside of the box instead of a kit. No worries, when you take out the the sponge layer for placing the mod and the paper board under it, you will find there is an Elabo Mini atomizer, a user manual for the Elabo Mini atomizer and a user manual for the Sinuous P80 mod, a USB cable, a ws01 triple 0.2Ω coil head for 40-80w wattage.

Wismec Sinuous P80 Kit measures 33.5mm long, 28.5mm wide and 125mm high. It features a unique centered 510 spring-loaded connector. When you screw the Elabo Mini atomizer on it, they look quite a straight shape.

The Elabo Mini atomizer has a capacity of 2ml and can be disassembled into four parts totally, mouth piece, the integrated atomization tube and liquid tank, coil head and the base.

To fill the liquid into the tank, you firstly need to pull out the mouth piece with much force. Push the black top cap along the arrow direction, you will be able to fill the liquid in the tank through the white filling hole. On the base, there are two airflow holes which are adjustable.

The Wismec Sinuous P80 box mod features a side LED screen. Specially, its upper part is the fire button. At its bottom, there are two adjustment buttons and a USB port for charging.

The battery compartment at the bottom features a pull-open lid. When you pull open the lid, you will see the round-shaped battery compartment only for one battery. After you installing the battery, you press and push close the battery lid with a click sound.

By pressing the fire button five times continually, you turn on or off the mod. By pressing the fire button three times continually, you enter into the mode option interface. By pressing the two adjustment buttons, you can make choice between the mode options, including VW, bypass, TC-Ni, TC-Ti, TC-SS, TCR-M1. Under different mode, the screen displays different information, including temperature, watts, voltage, current, resistance and remnant battery capacity.

By pressing the right adjustment button, you can swift options of LED color, logo, preheat and time out.

Though its maximum power is 80 watt, it can still produce very big vapor.

In summary, Wismec Sinuous P80 Kit is well designed with its good hand feel and its compact size is very convenient for carrying around. Though it doesn’t have a very high maximum wattage like some other Wismec devices, it still produces big vapor.

Oumier Wasp Nano RDA Review– Compact Size and Strong Explosiveness


Intro: Wasp Nano RDA is compact-sized but can produce huge vapor.

“Hey,are you biting a box?” Not really! Of course I’m not biting a box. It has atomizer on it! Well, it’s too small to be noticed. This tiny atomizer has caught lots of eyes among us and today we are gonna to talk about it–WASP NANO RDA.

WASP NANO RDA is a single-coil RDA atomizer released by Oumier Vape in 2017.

It comes with two colors, gold and silver. The one I have is gold color. When you open the black “honeycomb” (packing box), there is a Wasp Nano atomizer, hexagon screwdriver, screws for locking the coils, Muji cotton, o-rings and a hollow 510 electrode screw.

The atomizer is faint yellow. The two black o-rings look very much like the bottom of a “wasp”, don’t they? Its name really matches the reality, but it spits vapor instead of poisonous stinger. Waps Nano RDA has a diameter of 22mm and it measures 22mm high. Even though in the RDA atomizers, there are crowds of RDAs, Waps Nano RDA can be a strong performer of compact size.

Wasp Nano is made of atomization cap and base. The amber-colored material of the atomization cap is PEI (Polyetherimide) Pei is strongly high-temperature resistant and erosion resistant. The Pei material is usually used for some dual-coil atomizer with huge calorific value.  The integrated atomization cap of Wasp Nano RDA also adopts PEI material. It can effectively insulate the heat from the coil.

Heat insulation is especially important to atomizers like Wasp Nano RDA, mini-sized but producing huge vapor. Besides, between the volcano-shaped drip tip and the electrode deck, there forms a small atomization tube, which is good for the gathering and emission of the flavor.

The silver-plated base is very simple and mostly occupied by two big kitchen-knife-shaped electrode deck. At their first sight, many vapers think it has a presser-styled coil lock. Well, it’s not the truth.

At the place where the “knife handle” of the positive and negative electrode decks are, there is a screw respectively for fixing the coil. Besides, there is a groove at the place for putting the coil, which can prevent the coil end from falling off when we build the coil.

Such design is easy for building both the thick fancy coils and ordinary round coil. The breach of the “knife handle” makes it quite easy to process the coil ends. No matter the holes or edges of this atomizer base, I did not find any defects like burrs. Its workmanship is quite good.

Since it doesn’t adopt the presser structure, why it has such a big electrode deck? Originally, in the center of the positive and negative electrodes, there is a inflow hole respectively, corresponding to the two inflow holes on the cap. The airflow passes through the inflow holes on the electrode deck and blow the coil directly. Such airflow system is more direct and fierce, which is good for lowering the temperature of the coil.

On the other hand, since the inflow holes are in the middle part of the WASP Nano RDA and the inflow holes are canceled at the bottom, which make the bottom be sealed more tightly and reduce the possibility of leakage caused by overfilling the cotton. Wasp Nano RDA is small-sized, but its liquid storage is unexpectedly large.

Correspondingly, center airflow system imposes harder tests on how the atomizer performs with the flavor. Then how Wasp Nano RDA performs with the flavor and vapor. Let’s have a test!

I have been expecting such a dripping atomizer with fancy single-coil for a very long time. Thus for this time, I choose the Clapton NI80 triple-wired fancy finished coils. Its circle diameter is 3mm, twisted in 6 circles and its resistance is 0.26Ω.

This coil is twisted by three A1 wires and wrapped with 40G N180 heating wires. Its heating area is very big and its width is very large which brings a high request on the electrode. The good thing is that Wasp Nano RDA is completely qualified to it.

Generally, the cotton ends of finished coils are in the same direction, but this is not the fact of Wasp Nano RDA. So, we need to process the finished coils before putting them into use. After installing the triple-wire Clapton coil with 3mm circle diameter on the atomizer, you will find the distance between the coil and the electrode deck is about 2mm. No need to worry that the coil might touch the electrode deck thus causing short-circuit.

Though the bottom space of Wasp Nano RDA is very large enough for inserting in more cotton. But after I tried several times, I found that if there were too much cotton inserted in the bottom and too much liquid stored in the cotton, it would be very easy to cause frying of the liquid. But if the volume of the cotton is proper, frying will not happen.

Thus, I suggest that the volume of cotton should be not overmuch. Picture above shows the most proper volume of the cotton.

The liquid for testing is the No.6 liquid of 562 type. Firstly, since the coil is fancy coil, the vapor it produces is quite satisfying. Wasp Nano has quite small a size but unexceptionally strong explosiveness. Its performance on the taste is also praiseworthy. The tobacco flavor of No.6 will be enlarged and its cooling flavor is slightly lowered, owing to the excellent airflow system. Such matching brings a pretty concentrated and soft taste.

But because it produces huge vapor, it’s quite easy for the vapor to be left on the atomization cap and the electrode decks, thus forming condensation piled up on the atomization cap and the electrode decks and needing cleaning.


  1. The design of a single-coil dripping atomizer is very innovative. At present, such atomizer is of very good play-ability but it’s very rare in the market.
  2. Its details of workmanship are well processed with no burrs. No findings of obvious Bug with the workmanship.


  1. It’s too compact to match the sub ohm resistance, and too high a wattage might result in too high temperature, thus burning mouth.
  2. Condensation will be easily piled up on the surface of the electrode decks and needing cleaning regularly.

Well, different minds think different. Is this WASP NANO RDA your type? Whether it fits for you? Try it and you will know. It’s now only sold at $14.99 at Urvapin! Shop now!

Ijoy RDTA Box Review– All-In-One Kit

I believe you are not unfamiliar to the words- “ecig mod”. The mod you usually see is post-liked or box-liked. There is another product that would brighten the eyes of the vapers, the integrated ecig kit, that is what we normally say AIO kit. With products skyrocketing in 2016, more and more AIO kit comes into our sight.

Usually, the impression AIO gives us is a compact battery-built-in box mod with an atomizer pre-installed with finished coils. But today, the AIO kit I’m going to introduce to you is a big-sized kit–IJOY RDTA Box.

Inside of the pack, except for the iJoy RDTA BOX kit and some regular accessories, there is also the brush for cleaning, finished coils, two finished fancy coils, a 510 drip tip adapter ring and a bilingual specification.

  1. Atomizer

The big-sized RTDA Box mod is matched with an atomizer whose diameter is 25mm. The structure of the atomizer is the same as the regular RDTA, separable as  atomization tube for heating and the liquid tank. However, its body is much bigger than the RDTA we normally see!

Especially when you screw off the atomization tube, you will see one of  the RDTA’s highlights–a huge liquid tank (I think it can be called liquid depot). The capacity is 12.8ml! Though the connector of the atomizer and mod is also gold-plated, but they are not regular 510 spring-loaded connector.

When you disassemble the atomizer, you will find there is not very much highlight with its structure. By and large, it can be disassembled into drip tip, airflow ring, cap for atomization, electrode deck and base connection ring. “Base connection ring ” is actually the “hollowed” liquid tank of the regular atomizer. Here, it plays a role in connecting the electrode deck and the liquid tank at the base. In lots of RDTA atomizer, you can also find similar structure.

The atomizer of RDTA Box mod is pre-installed with a DIY electrode deck with dual posts and four holes. Besides, inside of the pack, there is a spare 0.15Ω triple-coil, with which huge vapor is also accessible to the new vapers.

  1. Mod

It measures 28*55*105mm and weighs 249g. If you install dual 18650 batteries into it, it will weigh 339g. With its big size and heavy wight, if you carry this ijoy RDTA box 200w around and put it into your trousers pocket, I guess it can drag down your trousers in a minute. Undoubtedly, its portability is not so good.

The entire mod is D-shaped. Its hand feel is average and is just the same as the regular dual-battery mod. On the upper part of the mod, there is a “huge” fire button. The key travel and the feedback force is proper. When you press it down, you will hear a clear “da’ sound. Below the 1.26-inch screen, you can see the “-” button and “+” button. There is a USB port on the mod, but it can only used for upgrading softwares but not for charging.

When you open the sliding-open battery compartment, you will find the electrodes are gold-plated. Closing to the electrodes at the bottom, there is a stealth spring design. The hollowed-out battery compartment is very convenient for vapers to take out the batteries.

Ijoy RDTA Box mod is equipped with a liquid tank of 12.8ml capacity (I should say liquid depot)! When you screw off the sealing lid of the refilling hole beside the atomizer, you can fill the liquid into it (I should say “pour the liquid”)! Since the diameter of the filling reaches 1.5mm, even if you don’t use the filling dropper, you can just screw open the lid and pour the liquid in. There is a LED light in the liquid tank for vapers’ convenience to observe the left liquid.

  1. Function of the mod

The displaying interface is clearly separated into 3 parts. Except for the regular wattage, resistance and voltage, it also displays how many times the vaper has vaped.

Regarding the function of the mod, except for the Ni-TC, Ti-TC, SS-TC and TCR function, vapers can also set the output mode under the common-used wattage mode. Press the fire button 3 times continuously to enter into the menu, then press the “+” and “-” button to switch into “output mode setting”, when you press the fire button to confirm it, you will see four different output modes, norm, hard, soft and user.

The User mode could be the most special setting.

The User mode enables the vapers to customize the output wattage in the first 3 seconds. On the setting interface, there are 6 energy bars similar to the sign of battery remaining capacity. Each energy bar stands for 0.5s work time. Initially, six energy bars all have 50% energy left. Each energy bar can increase or reduce 5 gears. Each gear stands for 10% initial wattage value.

Take the picture below as an example. My initial wattage value is 75w, when the first energy bar increases one gear, then the actual output at the first 0.5s after firing up is 75w*110%=82.5w. After setting the first energy bar, press the fire button to make confirmation to move to the next energy bar to do the setting, and the like.

The effect of this USER mode is very similar to that of the “taste curve”, but it’s more fool-styled. As long as the vaper operates it several times, they can be proficient with it. The entire procedures can be completed on the mod, no need to connect it with the computer for setting.

When I install the self-contained stainless steel fancy coils, I tried it. Under the norm mode of the wattage mode, the mod has 1 second output delay. The output doesn’t explode instantly but is acceptable. Regarding its taste, it is nearly the same as the huge-vapor atomizer, slightly lower density and layering. But the volume of the vapor is magnificent.


iJoy RDTA Box is very different from the common “built-in”kit. No matter its shape, weight and sizes of all aspects, they all embody “big”. Dual-battery mod ensures a high-wattage output, at the same time it also has a long endurance.

Vapers can also use finished coils on it. Even if it’s for new vapers to use, it is pretty easy to operate. The most amazing feature of the mod is its fool-styled taste-curve adjustment–USER mode, which can satisfy the increasingly personified vaping habits of the vapers.

For example, some vapers like soft taste at the beginning then steady output. I like hard taste at the beginning then steady output. USER mode can satisfy both the two habits.

However, iJoy RDTA Box 200w also has some weaknesses.

It is not 510-threaeded connector. It can only adapt its self-contained atomizer and coils.

It’s too heavy and big-sized to carry around.

All in all, iJoy RDTA Box is a box mod of pretty good performance and great usability. It’s only sold $59.99 with free shipping. Shop now!

What is Low Resistance?

What is low resistance?

  1. On ecig device, there  appears warning sign displaying “Ohms Too Low”or “Low Atomizer”. Under such situation, the power supply of the mod is not normal and the atomizer cannot work.
  2. As a resistance measuring index term, for example, low resistance/low ohm, ultra low resistance/ultra low ohm.

Resistance is the most important parameter index, it has influences on several aspects such as the taste, vapor, mod.

Normally, low resistance can be interpreted in two ways: a. “low resistance” often mentioned by vapers (huge vapor low resistance coil)  b. when there is something wrong with the device and on it there displays such warning.

  1. Low resistance often mentioned by vapers

This is a general term of what we normally say about low resistance, huge vapor data, huge vapor coil and etc.

Though there is not a set index about how low a resistance can be called low resistance. But according to the common resistance of most vapers, the generally-said low resistance is resistance around 0.2Ω.

Apart from low resistance, there is a word named ultra resistance. This word is about the resistance below 0.2Ω, such as resistance between 0Ω and 0.2Ω.

  1. Low resistance warningon the device. (malfunction message)

Normally, devices display information such as “Ohms Too Low” or “Low Atomizer” when the resistance is too low. Generally, on the specification of a mod, there will indicate a specific range of the resistance, that is to say, the resistance range that the mod can support. Thus, we should make sure the coil resistance of the atomizer we use is within this range.

If the screen indicates low resistance, it means the resistance is too low to be supportable. Usually, several reasons can cause such problem.

  1. A. Short-circuit

Reason: Some mods don’t have the indication of short-circuit but display the information as “low resistance”. Reasons might be as follows, the heating wires contacting atomization tube, heating wires or metal debris on the base. Besides, metal debris on the 510 connector can also result in such a problem.

Solution: According to the analysis above, check if there is foreign matter on the parts of the atomizer. Clean the foreign matter and then check if the malfunction is solved.

  1. Virtual connection

Reason: Finished coils are not installed properly. The components are not connected tightly, or the coils for RBA is virtually connected.

Solution: Re-install the finished coils, or check whether the coils for RBA is connected tightly, whether the 510 connector for power supply is screwed tightly. Disassemble the atomizer and re-install the components properly and then check whether the fault disappear.

  1. C. Problem of the coils

Reason: The resistance of the heating wires are made too low, often caused by over-thick heating wires or false choice for the wire material (such as Ni200, ss316), incomplete oxide layers between the heating wires are not complete (when tightly twisted), hot-melting between wire and wire (generally found in N180 material).

Since the materials of TC coils are different, their resistances are usually lower than that of the wattage/ variable voltage coils. If you use Ni 200 coil under wattage mode, it  unavoidably will result in low resistance.

Solution: Firstly, make sure if the type of the coils or the heating wires are correct to match the output mode of the mod.

  1. Loosening of the atomizer components.

Reason: In daily use, some components of the RBA atomizer will gradually become loose. For example, we have surely screwed the screws for fixing the coil tightly, but after adjusting the position of the coil, we find the screws become loose again.

This is because when we pull to adjust the coil, the screws will also be pulled incidentally. In our daily use, we also find loosened screws.

Solution: Disassemble the atomizer and re-install the components. Check the connection of every components, especially the screws for fixing the coils and the insulation materials below electrode posts.

  1. Broken mod

Reason: The 510 connector of the mod is broken. Problems might be as follows, virtual connection, short-circuit, damaged system board, malfunctions.

Solution: If the warranty is overdue and you are able to deal with it by yourself, you can disassemble the mod and check if the 510 connector is damaged. If your mod is still in the warranty period, you can contact the vendor to consult the procedures and methods for maintenance.

Asvape Michael 200W TC Box Mod Devils Night Edition Review

Intro: Asvape Michael 200W TC Box Mod innovates the style of mod appearance!

At present, the industrial design of ecig mods in the market are mostly inclined to paint-sprayed panels or panels with carved patterns. Mods with a large quantity of patterns have never emerged in the mod market so far, thus many vapers choose to purchase mod stickers to greatly personalize the appearances of their mods.

The mod now in my hand has been rightly innovated with its appearance. Most area of the mod has been specially processed thus making the entire appearance more personalized. That is Asvape Michael 200W TC Box Mod (Devils Night)


When talking about ASVAPE, maybe lots of vapers don’t know this brand well, but I believe many vapers must know the box mod Asvape Strider. Asvape Michael 200w TC Box Mod succeeds the unique style of Asvape Strider box mod with the vertical-lifting paper box cover and the magnet flip top inside.

If you open the flip top, you will see the box mod embedded in the sponge. When you take out the box mod together with the sponge, you will see the product warning card, specification and USB below the mod.


Ergonomically, it conforms to the round mod structure. When it matches with the unique mod sticker of devils night theme, together with the gold panel, endowing this box mod an unparalleled shinning appearance.


The arc at the 510 connector can well match with atomizers with diameter of 22mm, 24mm or 25mm. The pattern surrounding the 510 connector is also full of a sense of science.

The theme color is covered on the mod by the technique of water transfer printing.

The industrial design of the button is very interesting. The fire button of the workmanship is very exquisite. In the middle of it, there is the logo of ASVAPE, surrounding it, there is printed with wheatears and words as “aequitas inasvape we trust”. The screen is in an Oval shape. The button is full of elastic force, and the feedback of clicking is very ringing.

In the light of craftsmanship, the battery compartment cover should be a casting part and is gold-plated on the frosted surface. The two batteries are connected in series, greatly improving the current passing rate. The inner wall of the battery compartment is made of insulation material, greatly avoiding the risk when using broken-sleeve battery.


VW Mode Range: 5-200w

TC Mode Range: 212-572℉/100-300℃

Bypass mode output voltage: total voltage output of dual batteries in series.

Supportable resistance range:

  • Bypass mode: 0.2-3Ω
  • Power mode: 0.08-3Ω
  • TC mode: 0.03-3Ω
  • VPC Mode: 0.08-3Ω

Since the manufacturer has provided the specification in the package, I will just list the basic operations.

On the upper left side of the screen, there displays the wattage/temperature. On the upper right side, there displays the working voltage, resistance, total voltage and battery status. At the bottom, there displays the mode and the system.

By pressing the fire button three times, you can lock the screen. By pressing the fire button five times, you will enter into the options. On the option interface, you choose the system and press “+” button to confirm the present mode, press “-” button to turn off the mod. Choose the mode and press “+” or “-” to switch between different modes.

–Actual Testing–                    

In using, I found the actual output effect is more violent than the displaying wattage on the screen. So, I suggest that vapers choose much lower output than the output they normally vape with in daily use.

The TC effect worths affirmation. It’s steady without very big fluctuation.

Under the mechanical output mode, the output voltage is the total voltage output of the two batteries, that is 8.4v. Since the voltage is too high, vapers should be cautious.

–Actual Experience and Problems Found Out–

The output is pretty violent and the TC mode is very steady. The working effect under curve mode is also satisfying and you can obviously feel the changing of output wattage.

It feels pretty good and the sticker is very comfortable for touching. The arc of the mod body can well fit the palm. The only defect is that the position of the firing button is a little bit low. For the vapers with big palm

In testing, I also found some problems. When the resistance is at 0.1Ω and the wattage is in full output, about 50 seconds later, the mod will be into over-heat protection. The mod burns obviously.

The 510 connector doesn’t have a protruding surface. After long-term use, the paint of the top will surely be abraded by installing and replacing the atomizer.

The firmness of the sticker is pretty good, but if it’s scratched by sharp objects or it falls down, abrasion will be caused. Vapers please be cautious with it.


This Asvape Michael 200W TC Box Mod really find a new path on the innovation of appearance, overthrowing the appearance style of the traditional mod. With its unique appearance and good performance, I believe lots of vapers will love it a lot!

OUMIER Maximus Max RDTA Review

Gained its great popularity by Wasp Nano RDA, the brand Oumier has stepped into the big wave of RDTA in 2017 and released a RDTA named Oumier Maximus Max RDTA. In this big wave of RDTA, it’s inevitably that there will be a phenomenon of homogenization. Then whether this newcomer released by Oumier will drift with the current?

Package is showed as above. The yellow one is the outside envelope. Compared with WASP Nano, the packing style of Oumier Maximus RDTA is not changed, but the craftsmanship and quality of the package has both risen by a notch.

Maximus Max RDTA has a diameter of 24mm. It is pre-installed with semi-transparent liquid tank, and there is a spare transparent glass tube. It seems that Oumier shows some stubbornness with its packing list. There is no Clapton coil in the packing list but a pair of single-wired finished coils with many circles. I regard this type of coil as the suggested data by the manufacturer.

The cap-styled drip tip is an integrated PEI drip tip. The caliber is the same size as 810. I have tried to install several 810 drip tip on it, but none of them are tight enough when installed on it. Vapers care a lot about the problem of condensation. Manufacturer has processed the inner wall of the drip tip with chamfering technique. In actual use, you will find the condensation hang on the inner wall of the drip tip, but the condensation will be blocked by the chamfering structure thus will not be inhaled into mouth.

In daily use, it can be disassembled into four parts. Except for the drip tip, top cap and the atomization tube, the oil tank and the electrode deck at the base can be disassembled for cleaning and maintenance. From the picture, you can see the refilling design of Maximus Max RDTA adopts the “middle-column refilling” scheme which is very popular some time ago, but it doesn’t need the operation of plugging. The “liquid seal” of the white refilling hole is a cross-shaped silicone with a hole on it. When refilling, you only need to plug the sucker of the liquid bottle into it.

Oumier Maximus RDTA is featured with the typical side airflow system. On the two sides of the atomizer, there are two thin air inlets blowing the coils directly. Vapers can adjust the size of the inlets according to their own data, but the components of this part will be slightly loose when they are moistened by the e-liquid, thus the components should be kept dry.

The four square cotton holes are very different from the common round holes in visual effect. The form of the electrode deck is very much like the MGNT RDA V2. The original dual coils on the electrode deck are locked separately without interference to each other. For locking the coils, you will need to prepare a screwdriver.

The liquid tank is clamped tightly between the electrode deck and base. The top advantage of such connection is that the electrode deck can be put up on the coil burning device directly to burn the coil, and when the cotton is prepared, it will be more convenient for the vapers to deal with the cotton ends plugged into the refilling hole.

Some vapers said that when using the coils of high consumption such as Clapton coils, a short supply of liquid will easily appear to the RDTA. The problem is whether the cotton ends are processed properly. If you want the liquid deflecting speed of the RDTA to keep up with the pace, pay attention to the following two skills: Firstly, whether the length of the cotton ends can form the shortest course for liquid deflecting. Secondly, it’s the processing of the cotton end. Without influencing the fullness of the cotton at the deflecting holes, the thinner the cotton ends, the speedier the liquid deflecting will be.

There are four holes connecting to the refilling hole on the middle column. That is to say, the liquid will be refilled into the liquid tank from the four refilling holes. After installing the coils recommended by the manufacturer, when you insert the cotton into the deflecting holes to reach the liquid tank, the advantage of the electrode deck can be easily seen. You can scatter the cotton ends and trim it much thinner. After trimming it into a proper length, you install the liquid tank and the base.

The coils given in the packing list are twisted with more circles than the average ones. Under normal output, they heat up very slow (I guess they are made of A1 material). You will need to adjust the output voltage at least at 5V, the heating speed will be satisfying. With the inlet holes fully open, when vaping at the data suggested by the manufacturer, you will find the resistance to suction is very obvious, the taste is very soft, and the working temperature of the atomizer is within an acceptable range.

The air inlets are long in some extent, and is very suitable for some wide coils. They are perfectly compatible with some Clapton coils with three or four wires twisted together. The coil showed above is the NI80/28G quadruple-wire/40G Clapton, which can bring warm vapor and more violent taste. As for the single-wired coil, I recommend the coil (A1/21G-22G/3.0 circle diameter/5-6 circles)in the picture above. When used on mech mod, this coil can also bring good experience, but the length of the electrode at the bottom is not very long, please pay attention.

The height of the liquid tank benefits the deflecting speed a lot. With the cotton being processed properly, even when the quadruple-wired coil above is used, there is no problem of the deflecting speed. Through the refilling system at the middle column, the Maximus RDTA with great compatibility fully shows the meaning of “infinite dripping”. However, this product stills have the problem of condensation hanging on the inner wall.  But it is a common problem of RDTA structure, and you can just wipe it with paper towel. No big deal!

Following the good fame of WASP NANO RDA, Oumier has released this Maximus RDTA and also used a large quantity of PEI material on it. The design of its electrode deck is very similar to that of MGNT RDA V2. The “electrode wall” in the middle also compresses some space for the atomization tube. When it is vaped under the same data, this RDTA will bring a much fuller taste than the regular RDTA with dual columns and four holes.

Though the top of the atomization tube also has the problem of condensation hanging on the inner wall, I think it’s an unimportant defect. After all, most of RDTA has such a problem. If you take a look at many of the homogeneous RDTAs in the market, you will find Oumier Maximus Max RDTA really has its own unique features and structures with high differentiation degree.

Transformation of Evic Series–Joyetech Evic Primo Kit

Today I will introduce to you the Joyetech eVic Primo 200W TC Starter Kit. The monotony of the mods emerged in the VTC period is in no way succeeded by this starter kit. Joyetech eVic Primo adopts three elements,  leather pattern, metal drawing and black flat lacquer, making it look more fashionable. The leather patterned paster is replaceable. There are spare pasters of different colors in the kit. Their hand feel are pretty cool and it’s very comfortable for holding.

The groove at the 510 connector on the top of the mod can effectively avoid the liquid from flowing into the electrode, thus protect the mod from damage. The push-and-pull styled battery cover can well seal the battery compartment. When installing the batteries, such design can ensure the steady work of battery. The layout of middle panel on the mod is very similar to that of the previous mods from Joyetech, and the screen is pretty big. At the same time, the pressing area of the firing button is also big and the pressing feedback is very ringing.

As a dual-battery device that can power up to a maximum 200w, the atomizer to match it must have very strong capability. The diameter of its top platform is about 25mm. The adaptability of the 510 electrode is pretty good. After installing atomizers, such as 528 RTA, Wotofo the troll RTA and some other atomizers with long electrode, on the mod, I found there was no gap around the 510 connector.

The box mod also adopts the self-made chipset of Joyetech. The operation of it is nearly the same to the previous Joyetech box mods, by pressing the fire button three times to switch the modes, quite easy. The box mod can be connected to the computer by the USB cable for upgrading the chipset and customizing the mod. At the same time, if you connect a RC accessory (not included in the kit) to the 510 connector, the Joyetech eVic Primo mod can be turned into a power bank to charge your phone.

The output of primo 200w is very average without the so-called violent feel. Its output stability is very high and the firing speed is good without delay. When powering an atomizer with 24mm diameter and fancy coils, this mod can still have steady performance.

Inside of the kit, there is a matched UNIMAX 25 atomizer. The diameter of it is 25mm, which is just fit for the width of the top of the box mod with great harmony. The height of the atomizer is much higher than the hot-selling Wotofo The Troll, and its tank capacity is pretty considerable.

The UNIMAX 25 atomizer is featured with top filling and top airflow system. In the light of the structure of the atomizer, this atomizer does not have the problem of leaking. Below the air inlet, there is a rubber ring that can strengthen vaper’s hand grip and can bring convenience for adjusting the airflow at the top.

Since the airflow system is at the top, the size of the coil looks much bigger. But the actual part for atomizing the liquid is not very big. The shell is for segregating the liquid and is as the part for internal air inflow. But the part for the liquid to flow in is at the bottom of the atomizer. The liquid deflecting efficiency of the coil is so good that can completely deflect all the liquid in the tank.

The appearance of the Joyetech eVic Primo is sturdy, business-styled and fashionable. When it matches the same-colored atomizer, it looks really pretty, and its output will not let the vaper down. The width of the mod is almost the same as the palm, and the leather pattern and its arc of the inner side will give the vaper a very comfortable feeling of hand grip.

The workmanship of the atomizer is not as good as that of the mod, needing improvements. Its top airflow system doesn’t have the problem of leaking, but when you vape, air will come in thus influencing the density of the taste a little bit.

All in all, Joyetech eVic Primo Kit in a large extent brings transformation to the appearance of the Joyetech mod series.

Smok Osub 80w Baby Kit Review –Compact size and Strong Power!

Today I will review a new Smok kit–OSUB 80w Baby Kit.

As you all know, Smok brand has released a large quantity of vaping devices, from 50w to 300w, a dazzling array. Then what unique experience this kit will bring to us. Next we will begin the review.

First, let’s take a look at the package. Obviously, the picture on the box shows the color of this kit in my hand–purple. No need to mention the trademark at the top left corner and the kit name below the picture.

At the back of the box, there are some basic information and warning words, and the package list. This will be mentioned in the following text.

When you tear open the plastic film outside of the box mod, you will see the Smok-styled package– black hat box and on the box you can see the trademark of Smok. When you open the lid, you will see the purple-colored mod on the upper layer made of foam. And there is a stray cord attached at the upper layer for the convenience that the user can drag it out.

Take out the items inside of the box, you will see the packing list including OSUB 80w, TFV8 baby tank, a spare coil, o-rings, a USB cable, an instruction book, battery warning card. It’s a little of pity that there is no spare glass tube.

From the battery warning card and the instruction book, you can see this kit is mostly for the new vapers.

The top cap of the pre-installed TFV8 baby atomizer is not fixed by the thread but the hinge. This makes the refilling more easy with no worry to drop or lose the top cap. You just need to screw open it and then do the refilling. Such top cap has another strengths, that is, it produces very slight intensity of pressure, thus alleviating the leaking problem at the coil.

The pre-installed coil and the spare coil are both dual-coils of 0.4Ω. On the surface of the coil, you can see the applicable wattage ranging from 40-80w, and the optimum wattage ranges from 55 to 65w. In actual use, I suggest you set the wattage according to your actual taste, after all, the features of every type of liquid are different.

On the front face of the box mod, there is the screen, “+”-”buttons, USB port and the trademark of Smok. The fire button is on the side face which is designed for the first web to hold. The actual contact point of the fire button is at the end that is close to the screen. The design that takes the other end that close to the trademark as a pivot, and the overall firing structure as a lever makes the firing more convenient and more labor-saving, and brings a very direct hand feel feedback. The mod is pretty compact and the weight is also at a medium level, convenient for carrying around.

At the bottom of the back face, there is printed with its belonging series-OSUB, the adapted battery–18650 battery and the maximum wattage and the controlling mode–80w TC.y cover at the bottom of the box mod is a highlight of this mod. You can close the battery cover by just pressing the battery cover. The hand feel feedback is pretty good without lose closing.


It benefits from the spring setting at the connection part of the battery cover. You just need to move the black switch with your fingernails. The battery cover will pop up.Very humanistic! No need to use great efforts to open it with your fingernails.

Compared OSUB 80w Baby Kit with a pack of tissue, you will find this box mod is pretty tiny and compact, easy to carry around. It’s more easier to put it into your pocket than a pack of tissue.

Even though it’s in a compact size and powered by only one battery, but during the time when I’m using it, I don’t feel the battery is in weak power or the battery powers up with delay. With a full charge, it can last for a whole working day. Unless you loaf on your job frequently for vaping, there is absolutely no pressure for the mod to last for a whole day.

In general, OSUB 80w Baby Kit is a kit mostly for the new vapers. The matched TFV8 baby tank can produce excellent taste and huge vapor. The refilling structure is pretty convenient. The pre-installed coil and the spare coil are sturdy enough to last for a pretty long time.

The mod can support a maximum wattage of 80w, making it fit for most DIY atomizer and heating coils. The design of the battery cover and the switch is pretty humanistic and easy for operation and using. Though it is powered by only one battery, but it can last for a long enough time for a working day.

But there is no spare glass tube for replacement. The mod is in compact size, which is only suitable atomizers of 22mm diameter.

Based on the features of the product itself, OSUB 80W Baby Kit can be a pretty good choice for new vapers to move toward advanced level, but it’s not the best choice for the advanced vapers. For working day, Smok Osub 80w Baby Kit is absolutely enough to serve you!


Smok G-Priv Review—Full Sense of Science and Technology

Intro: With the rapid development of electric cigarette field, it is a trend that more and more advanced technologies will be applied to electronic cigarettes. The Smok G-Priv 220w Kit released by Smok is such a mod with a full sense of science and technology.

Since 2016, it seems that Ecig box mod is entering into the touch screen era. From the first emergence of  SMY TOUCH BOX 100W, the manufacturers began to develop box mods with big touch screen one after another, from Hell’s Gate Touch 200w to Laisimo L3 200w, then to Teslacigs Touch 150 TC and Sigelei T200. Recently, Smok has also released its own touch screen box mod. Today, I will give a review on this latest Smok G-Prive with touch screen.

The package of Smok G-Priv is simple but not simple. G-PRIV succeeds the kit line of Smok.  Apart from the box mod, it also comes with a TFV8 Big Baby atomizer which is preinstalled with a V8 baby-x4 coil (dual wires, dual-coil, 0.15Ω, 30-70w, best 45-60w). Besides, the content list also includes v8 baby-t6 coil (triple-coil 0.2Ω 40-130w best 70-90w), silicon rubber case, USB cable, spare glass tube, spare rings, instruction book, warranty card, warnings for using the battery.

The appearance of this box mod is very angular and it adopts the matching color of red and black. The front side is the touch screen of 2.4 inch, the frame of which is the chrome-plated.

As regard to the details, there are three pressure relief holes in willow leaf shape, and a USB port. The inner space of the pressure relief holes is very big which is better for the heat dissipation. The USB port supports for upgrading and charging.

On the side, there is an integrated button both for firing the mod and locking the screen. The fire button succeeds the style of H-PRIV, but it’s of better elasticity with comfortable hand feel. The screen-locking button is a highlight which can give the user a better operation experience.

The connector on the top is the commonly used 510 connector. It is processed with scratch-proof technique, but the scratch-proof plate does not protrude from the plane on the top. When you install the atomizer, the paint around the 510 connector will still be abraded. Surrounding the scratch-proof plate, there is a carved arc, which can ensure a no-gap connection between the mod and atomizer. The carbon-fiber plane on the battery cover is of excellent workmanship.

The OLED screen is covered by a protective film.

The battery cover and the mod body is connected by four strong magnets. The connection is so strong that it’s pretty hard to separate them. There are dual batteries and gold-plated electrodes inside of the battery compartment. The electrode posts are of medium elastic force.  It’s quite easy to take out and put in the battery. A piece of heating sticker is sticking on the back of the battery cover. The overall battery cover is made of metal material, thus it’s quite heavy. Moreover, the workmanship is pretty good.

The accessory silicone rubber case is pretty suitable. When this box mod puts on this “garment”, the original edge of the kit is hidden and it presents a pretty low-key style. The experience to operate the original kit and the kit in the case is almost the same. Obviously, Smok has made pretty much effort on it.

Let’s see the operation methods. If you use the button switch, you just press the fire button five times continuously to switch on and switch off the kit, and you press the fire button three times continuously to lock the kit.

Next, let’s talk about the touch-screen operation. This is the main interface displaying the wattage, namely the interface when you vape under the wattage mode. In the middle of the interface, it displays the current output wattage and the wattage output mode. At the bottom, the “PUFF” indicates the draws that you have taken in that day and the limited puff to be taken in that day. The three icons at the bottom from the left to right displays respectively the actual current, the actual voltage and the resistance. In the middle of the interface, there is a circle displaying the wattage and you can touch the two sides to adjust the output wattage.

When you install a new atomizer, an interface will appear as showed in the picture. Press “yes” to confirm the new resistance. The test of the resistance is pretty accurate. This function has an old problem, that is, it can not test out the replacement of the atomizer. You will need to screw out the atomizer and press the fire button to make the screen display testing atomizer, then you install the atomizer on the mod and step into the interface of confirmation. Press the arrow on the upper left of the main interface,  then you can step into the main menu interface (as showed in the picture) and choose the detailed setting catalogue according to your own needs.

Let’s take a look at the wattage setting interface. The “Effects” on the top is the choice of output mode under VW mode, which is the exclusive technique of Smok.  There are five gears under this mod, from weak to strong, Min, Soft, Norm, Hard, Max.  The effect of every gear is pretty obvious and it is a quite practical function.

Below it, there is a pull bar to adjust the wattage. You can make the adjustment by sliding the bar or pressing “+”and “-”. At the bottom, it is the activate button. By sliding it to the right, you can activate this mode.

Pictures above are the main menu and the interface for setting the TC mode. The difference of the main menu under TC mode and the VW mode is just that the “VW Mode” in the middle  is changed into “TC mode”, the mode is changed into “output wattage and heating material”.

On the detailed setting interface under TC mode, the first line is for choosing the heating materials, including SS, Ni and Ti. The second line is for preheating the wattage under TC mode.

The third line is for adjusting the TC curve. If the vaper doesn’t have relative knowledge, it’s better for the vaper not to make adjustment by himself. The fourth line is for adjusting the resistance and the adjustment range reaches +-0.05Ω. This function is a very good solution to the problem that the automatic testing resistance of some TC coils is not so accurate. It’s worth noting that this adjustment is also applicable to the wattage mode.

On the puff setting interface, the first line is the puffs that have already been taken, the second line is for setting the limit puff. If the number is 0, then there is no limit puff.  The way to adjust the limit puff is the same as the way to adjust the wattage. The third line is for resetting the daily puff.

On the details setting interface, the first line is the only  system identification code. The second line is the model of the mode and the system version. The third line is the screen timeout.  By pressing the arrow at the right, you can set it and the range is from 1.0s to 24.0s. The fourth line is for adjusting the time including year, month and day. The fifth line is for restoring the factory settings.

Let’s take a look at the configuration of this device. The difference between TFV8 Big Baby Tank and TFV8 BABY Tank is its tank capacity and the measurement. The tank capacity and measurement of Big Baby are both larger than those of Baby Tank, but the RBA cannot be in common use.

Metal material is used so much on the mod that when the batteries are installed in, the mod is pretty heavy. It is worth noting that this dual-battery mod can reach an output wattage of 220w. Let’s take a look at the actual effect.

Since the built-on atomizer (TFV8 Big Baby)is not very different to the TFV8 Baby, let’s just take a look at its effect. The picture above shows the vapor effect of the preinstalled v8 baby –x4 coil (dual coils twisted by dual wires 0.15Ω 30-70w) under 60w. The originality of the vapor is pretty good and the vapor is huge and dense.

The vapor produced by the v8 baby- t6 coil (triple coils 0.2Ω 40-130w optimum wattage 70-90w) is much huger than X4, the flavor is rich, but the density is lesser. When it’s used under Max mode at 130w, the liquid deflection is not quick enough thus causing burning of the coil.

In general, compared with TFV8 BABY Tank, this atomizer can store more liquid, thus enforcing the duration time of this “vapor beast”. But the connection of the drip tip is not the generally-used 510, which might not be so convenient for those vapers who is accustomed to changing drip tips. Its vapor production is nearly the same as that of TFV8 Baby Tank.

Let’s take a look at the wattage output testing. I used three mods, from left to right, they are ipv8, Wismec RX200W, smok G-priv.

Atomizer and its data: geometrical RDA Kanthal A1 coil, wire diameter 0.6mm, circle diameter 3.0mm, 6 circles, quadruple coils, 0.11Ω resistance.

The first two mods both use 200w wattage. G-Priv is under Max mode 200w wattage. You can clearly see the output of G-Priv is more violent and the vapor is much denser. Besides, when the mod was under testing, the chipset of the mod didn’t jump into the overheat protection mode.

We can say that the chipset used by Smok has a pretty good performance. There is no firing delay.  Under wattage mode, its chipset performs even better than the DNA 200 chipset. Its performance under TC mode does not have problem of the inaccuracy of temperature control that appeared in the past time.

Let’s make a summary.


  1. Combine supercar element with electronic cigarettes, giving it an appealing appearance.
  2. An integrated fire button enable the user to switch on it in more ways with more ease.
  3. The user interface (UI) of the touch screen is simple for operation and easy to understand.
  4. The lock button further facilitates the operation.
  5. The application of the silicone case can not only protect the mod but also change the appearance style of the overall mod largely.
  6. The resistance can be adjusted slightly, solving the problem that fixed resistance cannot make an optimum effect.
  7. The maximum violent output 220w is an actual wattage but not a fake value. Output is steady with no delay, even under TC mode.


  1. The anti-wear capacity of the mod is not good.
  2. The scratch-proof plate at the 510 connector does not play its role efficiently.
  3. The sensitivity of the touch screen is not so good as that of Smartphone.
  4. When replacing the atomizer or rebuild the coil, the screen doesn’t display the interface for choosing the new resistance.

To sum it up, except from some details, Smok G-Priv 200w Kit is actually pretty good. It has a pretty fashionable appearance with a full sense of science and technology. It has a violent output of 220w. Its TC effect is pretty steady. Its operation interface is pretty brief and intelligible. Most of the weaknesses can be solved by system upgrade later.

With more and more touch-screen mods being release, relative technologies are also improved day by day. With the development of mods, it will be a trend that the operation interface will be more brief and intelligible, the operation will be more handier, and the appearance will be more distinctive.

The package of Wotofo Serpent SMM RTA adopts the Wotofo-styled package, the colorful printing drawer-styled paper box.

But for this time, its box gives me a different feeling. It really looks like a box of cigarettes, doesn’t it? I really like this design, and the gorgeous colors are pretty charming.


When opening the lid, better to say when pulling out the box, the first thing you see is the Wotofo’s little card and the no-need-to-read instruction book of the atomizer.

My first impression when pulling out the box is “considerate manufacturer”. There a three glass tubes in total, among which, two are for replacement. The manufacturer is considerate, isn’t it?

In the main layer, there is a PEI drip tip, two replaceable glass tube and an atomizer.

When you take off the main layer, you will see a bag of cotton, a bag of spare rings and a screws,  a bag of heating wires and a screw driver.

When you install the drip tip onto the atomizer, they looks pretty coordinated with each other and the workmanship is also pretty nice. Some vapers might ask that what’s the difference between it and the ADVKEN CP RTA. Just take your time to read the content below.


The atomizer can be disassembled into 6 parts, including drip tip, top cap for filling, atomizer tube, glass tube, base and the air adjusting ring.

The edge of the drip tip is well processed and is very round. The heating insulation capacity of the PEI material is pretty good.

The pictures above shows its funnel-shaped inner wall, and the processing of the inner wall is pretty smooth. The best 510 drip tip with a big caliber that I have used so far can be discussed from several points below.

The first point is the height of the drip tip. The heights of many resin 510 drip tips are too low, resulting a bad mouth feeling. But, the height of Serpent SMM drip tip is very suitable. The Second is the thickness of the drip tip. It is neither too thin or too thick. The third is its funnel shape to prevent condensation. The fourth is the polishing of the drip tip, whether it is round and smooth.

On the external part of the top cap, there is an oblique angle. The processing of the edge is not very round and smooth. When you touch it slightly, it’s a little bit sharp but doesn’t influence the hand feeling.

The internal part of it is different to the top cap of other atomizers. There are three layers and two rings. The sealing is pretty good.

The atomizer tube is very average at my first sight. The “serpent smm” is carved on it and the polishing is also good. All in all, it’s very similar to the CP atomizer, but pay attention to the details.

First, look at picture 1, the arc of the rounded angle is considerably big, which is for the reflux condensation.

Second, look at picture 2, the height of the airflow tube is very short, which can expedite the vapor to enter into the mouth, retaining the temperature of the vapor and the taste of the liquid after vaporization.

Third, look at picture 3, there are two gathering designs. At the same time, the diameter of the air tube is smaller than the CP atomizer, so the vapor is more concentrated and the flavor is much denser.

The details above are the biggest difference between SMM and CP. Below are some other differences between SMM and CP.

The glass tube succeeds the consistent thickness and consistent rounded edge of Serpent series.

The base of Wotofo Serpent SMM is my favorite base among GTAs.

First, there are two electrode posts and four holes on the base. No matter you wind the coil in either direction, you can well install it.

Second, the cross-screwdriver is very good for using. (wear-resisting and easy for screwing)

Then, there are four outlets. Seemingly the air blows the coil from the side, actually, it’s not. We will talk about it later. Next, you can insert the cotton into the holes directly, no need to adjust the position as you might have to do on the CP atomizer, which is very easy for using.

At last, there is an air inlet hole at each side and the two holes are not connected, bringing a big space in the middle.

The designer makes a rational use of this space for reserving the liquid, making it different from many other RTAs and GTAs in the market.

Next, we can talk about the second difference between wotofo serpent smm rta and CP atomizer, that is, the way how the airflow blows the coil via the air inlets. The air inlet of CP is at the bottom and the airflow only blows the bottom of the coil. However, the airflow blows the coil of the Serpent SMM tridimentionally. By adjusting the coil, you can see the upper air inlet is facing the middle and the side of the coil. And the air inlet at the bottom is facing the bottom of the coil. That is to say, the coil gets blew by airflow from three directions. In this way, the taste will be better and the vaporized vapor will also increase.

The most direct embodiment is that the unit density of the vapor increases greatly. In fact, a few atomizers have adopted such an outlet design.

But I have to say, there is no such an atomizer of which the air inlet condensation is good enough by bottom inflow. Why is that? It’s because when you finish using the atomizer, the temperature of the coil is still high enough to vaporize the liquid and then the vapor will sink into the air hole thus forming the condensation.

Good news is that Serpent SMM RTA can well avoid it, since there is no air holes at the bottom. The air holes are on the side, and there is some distance between the air holes on the side and the bottom. When using the atomizer, if you shake the it, the condensation will touch the cotton at the ends, thus you will not see the condensation at the air inlets.

At the reverse side of the base, there is the gold-plated electrode and some information such as the Logo.

The inlet ring of this Wotofo Serpent SMM RTA is detachable. There are slots on it, thus it will not rotate 360-degree. At the same time, it can well help disassemble and clean the atomizer.


I believe many vapers have the CP atomizer. In the light of taste, Wotofo serpent SMM RTA is much denser than CP, the vapor is very rich and the reduction degree of the vapor is much higher.


  1. Creative design
  2. Excellent taste
  3. Much shorter than CP


  1. The base is hard to clean and the liquid tank below is hard to reach for cleaning.
  2. The resolution degree is very ordinary, similar to that of Merlin Mini.
