Limitless Gold RDTA Review—Replaceable Deck

Limitless Gold RDTA is the newest tank released by Limitless company.

Limitless company is a Canadian manufacturer and used to be a partner of iJoy  the Chinese brand. But at present, they have become two separate companies. Limitless Gold RDTA, designed exclusively by Limitless company, is the upgraded version of the previous Limitless RDTA tank.

When it comes to RDTA, some new users might not know it well. RDTA is shorted for Rebuildable Dripping Tank Atomizer, meaning that it’s a dripping tank.

Before I give the demonstration of Limitless Gold RDTA, I’d like to talk about the RDTA category.

As the latest atomizer category, RDTA, featuring both the unique flavor of dripping atomizers and the storage function of tanks, has attracted great attention from the vaping group.

When it emerged in the market firstly, it received great response. But the hot wave decreased soon in a short time. The reason of this phenomenon is due to its incomplete structural design on its first emergence. Oil leaking, complex structure, inconvenience for installation and cleaning, were the factors that constrained its development.

In 2017, after long silence, RDTA appeared in the market again with the problems above optimized.

Structure Decomposition

Generally, the structure of RDTA from top to bottom is drip tip (might be integrated with top cap), atomizer cap, atomization warehouse (might be integrated with top cap and drip tip), electrode plate, filling ring (might be integrated with electrode plate), oil tube (normally glass material), 510 electrode plate.

The upper part of RDTA has no difference to the RDA. The electrode plate of the two categories are both wrapped by atomization warehouse.  But the RDTA has an additional part— the oil tank.

Structure Details

The atomization warehouse usually wraps the whole electrode plate, including most part of the filling ring. Such design, in one aspect, it’s for the appearance; in the other aspect, it’s for sealing the filling hole (the early RDTA leaked because the filling ring is not sealed tightly thus leading to decompression of the oil tank).

Generally, RDTA is structured with U-shaped dual-post four-hole electrode posts. Also, there are also designs of presser-styled electrodes and non-electrode. After all, these different kinds of electrodes come from the existing electrode posts types of RDA, which can bring simple and convenient coil building experience.

The wicking of RDTA is different to that of RDA. You cannot just put the cotton end into the bottom of the oil tank to lead the oil to the coil. If you operate like this, the oil-defecting distance will be too long. After half tank of the oil has been finished, the oil defecting speed will become slower. Also, the oil in the cotton cannot be deflected completely and is difficult to deal with.

We treat the oil tank of RDTA as a temporary oil tank. Every time when you vape, the atomizer will be slanted, then the oil will be deflected into the cotton. But when the left oil in the oil tank is very little, if you invert the atomizer, the oil can still be deflected into the cotton thus to the coil.

Thus, I suggest vapers can leave each of the cotton end about 1 cm longer than that of the RDA when you do the wicking. This is not only pleasing to the eyes, but also will not waste too much oil, and the operation is much simpler.

OK, hope you guys have had a good knowledge of RDTA.

My first sight at Limitless RDTA tank, I was attracted by its gold pin in the tank.  The tank has a juice capacity of 4.75ml which is big for a RDTA.

The drip tip and the atomizer cap are an integrated part. By screwing it off, the gold plated deck comes to your eyesight. It is absolutely a unique design and the deck is replaceable with two options. With the replaceable decks, you can have different vaping experience.

It has a 25mm base with a unique bottom airflow design that shoots the air directly under the coils. It also features a top adjustable airflow control with Limitless triangles as your airflow slots.

To best match Limitless Gold RDTA , I suggest the Tesla Nano 120w box modLimitless Arms Race 200w and  iJoy Captain PD270 234W.

How to Clean Fancy Coils –Coil Maintenance!

How to clean fancy coils? Have you ever had a problem to do the coil maintenance? Or do you just throw the burnt coils away? That’s too wasteful!

Fancy coils (also understood as twisted coils or intertwined coils) are intertwined by multiple heating wires. The heating area of it is larger than the ordinary coils, thus no matter the flavor or vapor, they are superior to the ordinary coils.

With the advancement of e-cigarette industry, heating wires made of various material have emerged in the market. The fancy coils, intertwined by heating wires, known as finished fancy coils, can bring much convenience to vapers who like fancy coils.

After vaping for several days, there is always accumulative carbons adhered to the coils. It not only looks gross, but also influences the taste. When you vape on it, you will taste a burnt flavor unavoidably. On seeing this, vapers would wash the coils and change the cotton.

In fact, there are lots of points that we need to pay attention when we wash the fancy coils. Here I will give a simple elaboration on it.

The picture above shows the triple-wired Clapton fancy coils made of NI80 material that has been used for 4 days and are not cleaned.  It’s easy to see that there are lots of accumulative carbons on the coil and the outside of the coils is blacked obviously.

When I vape with it, the burnt flavor is pungent. Of course, this picture is just for this test. In daily use, I suggest you guys to clean your coils and change the cotton every one or two days.

The accumulative carbons might be blasted away because of the high temperature and then adhere to the inner wall of the atomizer.

After removing the cotton, we install the tank onto the box mod, just like what we do when burning coils.  Then we adjust the voltage to 3.0V.

Don’t adjust the wattage too high. If the heating temperature goes too high, the accumulative carbons will be blasted away and burn the vaper’s hand, even worse to melt the coils.

The strong burnt flavor you smell when you heat the coils is caused by the accumulative carbons on the coils.

When the coils are burnt like a coal, you can easily see the accumulative carbons adhered to the coils just like scabs.

When the coils are burnt to red, you can stop pressing the fire button and then put the coils into the warm water (40-60°). Attention,  don’t wet the mod.

Please remember that don’t power it. Don’t power it! Don’t power it! Or the coils will be short-circuited and will melt in the water.

Then why should we use warm water?

In fact, the process that you put the burning coils into water to cool them is called “quenching”.

If the temperature difference between the water and the coils are too big, the coils will be embrittled. That is to say the coils will be easily broken.

Again, why should we use warm water? The reason is the temperature of the water will have a direct influence on the life span of the coils.

After repeating the process “quenching” several times, you will see there are grains of carbons in the water.

Then, you can use the vape brush to clean the coils. With the vape brush, you can clean away the accumulative carbons between the wires.

The brush part of such brush is normally made of stainless steel or brass.

Coil Maintenance

When we wash and brush the coils, we should take into consideration the following points.

  1. We should brush the coils softly but not too hard.

The outer wire of the coil is always very thin. If we brush it too hard, the outer wire will be easily damaged.

  1. When we do the brush, we should brush it in one direction but not back and forth over and over again. I usually brush from the left to the right and then from top to the bottom. If you brush the coils back and forth over and over again, you will disorganize the wires intertwined with complicated process and enlarge the gap between the outer wires.

Later, we can disassemble the tank into parts and put them into the ultrasonic cleaner to clean them. In this way, the dirt in the tank will be all cleaned out.

The last step, after we air-dry the tank then we can install it onto the box mod and burn the coils to make adjustment. Then let the coils cool to the room temperature.

This step is not only to adjust the coils and see if the coils are heated evenly, it also has the advantage of “tempering”, which can improve the performance and life span of the coils.

Let’s make a comparison between the coils before cleaning and after cleaning.

In fact, when you use fancy coils, you might as well to choose the oil of low sweetness and good quality. In this way, the accumulative carbons can be reduced directly.

Fancy coils can bring vapers with high-qualified vaping experience, but because of the expensive materials and the complex intertwining work, the price of fancy coils are far more expensive than ordinary coils. When we use fancy coil, we should know how to do the daily cleaning and maintenance.

Just like the car maintenance, we should not only have a good taste on cars but also know how to maintain them. If we do the coil maintenance properly, we cannot only prolong the life span of coils,  but also bring their good performance into full play, accordingly, bring us better vaping experience.

Tesla Biturbo Mech Dual RDA Starter Kit Review—Two RDAs!

I have to say, for this time, Teslacigs impresses me again with its new release—Tesla Biturbo Mech Dual RDA Starter Kit. It has the ability to fire two RDAs at the same time!


Tesla Biturbo

Teslacigs has gone further and further on creativity with the successive release of Tesla Nano 120w box mod, Tesla Invader 2/3 box mod and Biturbo.

From the appearance, Tesla Nano looks just like an old lighter at my first sight. Then it’s cool to find that there are actually two RDAs on it. Users can add  two different juices of different flavors to enjoy a complex and unique taste on vaping.

The overall Tesla Biturbo Mech Dual RDA Starter Kit is constructed by the drip tip and top caps (together), two RDAs, and the battery compartment.

Tesla Biturbo

To build and burn the coil, you have to remove the top cap and trip tip. The two RDAs are both constructed by two electrodes and you build them just in the normal way separately. The most unique feature of this starter kit is that you can drip two different flavored juices to create a combined flavor.


Tesla Biturbo


On the side of the starter kit, it is the fire button. At the bottom of the kit, there are two black round buttons that you can control the two channels—meaning the two RDAs. There are two LED lights on the lower front side.

Except for vaping a complex combined flavor, you can also choose to vape two different pure flavor just by open or close either of the two RDAs.

To power the kit, you need dual 18650 batteries. Press the fire button five times consecutively, the kit will enter into the stand-by mode. By pressing the channel selection button A/B to open or close the channel A/B.

When channel A is opened, the LED A will be on and RDA A will work upon pressing the fire button;  when channel A is closed, the LED A will be off and RDA A will not work upon pressing the fire button. When channel B is opened, the LED B will be on and RDA B will be on and RDA B will work upon pressing the fire button; when channel B is closed, the LED B will be off and RDA B will not work upon pressing the fire button.

Guys, please remember, safety is prior to vaping. Tesla Biturbo takes full consideration of safety. Four kinds of protections as below:

  1. Over Puffing Protection: The device will be deactivated after continuous puffing of more than 10 seconds. The corresponding LED will flash for 8 times and the device will enter into the stand-by mode.
  2. Reverse Connection Protection: If batteries are inserted incorrectly, the device will fail to power on and will prevent any damage to the chipset.
  3. Low Voltage Alert: When the voltage drops below 7.5V, corresponding LED will flash for 15 times and the device will power off.
  4. Atomizer Short-circuit Protection: When an atomizer short circuit occurs, corresponding LED will flash for 5 times rapidly and the device

How to Clean Atomizers—Atomizer Maintenance


Is atomizer maintenance necessary? Do you clean your atomizers after vaping? The answer surely is yes! How to get rid of the oil smell in the atomizer? How to wash the atomizer? Any matters need attention?

  1. How to clean atomizers in the daily use?

There are many ways to clean atomizers, for example, alcohol, clean water, ultrasonic cleaner and etc. Today I will share my special secret for cleaning atomizers with you. Preparation: baking soda, a bowl of clean water, tweezers , cleaning cloth and clean tissue.

  1. Disassemble the atomizer into three main parts– top cap, oil tank and base. After that, then you disassemble the rings. If you are not sure if you can remember all the positions of the rings, you can put them away according to the order when you disassemble the rings. But please pay attention that don’t disassemble the small accessories in case that they might be lost in cleaning.
  2. Based on the proportion of 1:20, blend baking soda and cool or warm water evenly. Put the atomizer without rings into the water and after 10 minutes, you will see the water becomes light yellow. At this time, you can stir the atomizers in the water to erase the impurity of the atomizers. Then get the atomizers out of water with a tweezers and put them into another container.
  3. Wash the atomizers with clean water, and wipe the water on the atomizers with dry cloth or tissues, or let them dry in the open air.

Tip: baking soda can wipe off the impure flavor in the atomizers.

  • How to store the atomizers when you don’t use them?

The mainstream atomizers in the market are mainly made of 304 stainless steel and 316 stainless steel. How should we store them after using them?

Firstly, you need to clean the atomizers in the water. After cleaning, make sure the atomizers and rings are dry without water left in case that the atomizers get rusted. When assembling atomizers, you can smear the rings and the threads with a little bit of pure VG to avoid the threads from rusting and dead-locking and avoid the rings from weathering. Pure VG will not add impure flavor to the atomizers. 

2 .How to prolong the life span of an atomizer?

An atomizer is composed of several metal parts. If you use it improperly for a long time and pay no attention to the details,  problems can be easily emerged—screws getting scrapped, threads becoming smooth, leakage leading to scrapped rings,  insulation spacer getting out of shape. How can we prolong the life span of an atomizer?

  1. When building coils, we just need to lock the coil to a proper state, but don’t screw the screws way too tightly.
  2. The smoothing of screw threads usually appears when we install it on the mod. Thus, when you do the installation, you should not use a brute force to screw the screws. You should joint the threads properly before you screw it.
  3. Leakage is the main reason why we give up an atomizer. Before we throw it away, please build the coil again with all your heart. Make sure if it’s the problem of the structure of the atomizer, and then check if the rings can well seal the gaps.
  4. If you burn the coils improperly, the overheat will lead the insulation spacer to be out of shape and thus be scrapped. In this case, we can shorten the burning time, or burn the coils discontinuously to cool the atomizer and ensure the completion of the insulation spacer.
  5. How long is the life span of an atomizer?

How long is the life span of an atomizer? This is a question that I was asking when I was a newbie. I normally bought two pieces of atomizers of the same model for replacement. But later I found it was meaningless.  The main parts of atomizers are made of metal and are very firm.  The easily worn-out parts are the accessories, such as glass tube, ring, screws, threads,  insulation spacer and so on. Most of atomizer packages include spare parts of these accessories.

Proper operation and maintenance will greatly prolong the life span of an atomizer.


Atomizers are sorted as the mechanical metal products. As long as we learn how to maintain them, you will find that you can own them for a pretty long time. As time goes by, the atomizers will be imprinted with the sign of aging, but how interesting is it to discover that!

Limitless Pulse Pod System Starter Kit Preview—Vape Anywhere at Any Time!

Limitless Mod Co., cooperating with PLY Rock, has manufactured a really portable starter kit named Limitless Pulse Pod System Kit.

Limitless Pulse Pod

I guess it’s a universal problem for our vaping friends to choose a proper ecig to take with when going out. The Dragon-Boat Festival of China is around the corner, and also brings this problem to me. Personally, for carrying around, portability is my first concern, but not the big functions that I may pay great attention when I am vaping in the office or at home. I have decided to take the Limitless Pulse Pod for the short-distance trip in the coming festival.

Limitless Pusle Pod

As shown in the picture, Limitless Pulse Pod System Starter Kit is a portable all-in-one device with a skinny body, totally different to those big ones. Put it in your pocket just like a pen!

Limitless Pulse Pod System Vape is small, but it’s perfectly configured. It is composed by a changeable pulse pod and a chargeable battery part (I may call it mod). The pulse pod has a juice capacity of 2ml, just like a cartridge.

Limitless Pulse Pod

The Pulse Pod is easy for refilling. You just disassemble the mouth piece, open the red plug and fill it with the juice bottle. Mind that there should be now left liquid outside of the tank. A thin needle tip bottle will be a good choice for filling the tank. As coils may be burnt too much and thus influence the flavor, the heater in the pod also needs to be changed. How often you change the pod depends on your personal vaping habit. It’s the similar question to how long does a limitless pulse pod last, thus the answer is the same.

Limitless Pulse Pod

Limitless Company is also considerate to release a separate pulse pod pack exclusively for this kit. Three pieces in a pack and it’s quite easy to change the pod which you can see from the picture above.

The battery has a capacity of 380mah and it is rechargeable by a USB cable. The button on the center of the Pulse Pen allows you to change the color of the LED light system.

Limitless Pulse Pod

For the package, Limitless adopts its usual style—the hat box made of paper. On the front side of the box, there is the LOGO and the product name as well as the name of its cooperator PLY ROCK.  Inside of the box, there is a Limitless Pulse Pod System Vape Pen, a Pod and a USB charger.

The price of Limitless Pulse Pod System Kit is also affordable and sells for only $25.95. Shop now!

Tesla Invader 2/3 Box Mod Review—Multi-functional Voltage Scheme

Tesla Invader 2/3

Tesla Invader 2/3 is the latest creation from Teslacigs Invader series. It has been upgraded entirely, no matter its performance or functions, they both have been improved largely. Of course, its appearance is also improved. The most special part of Tesla Invader 2/3 box mod is its setting of the battery scheme, which can switch between dual-battery system and triple-battery system.


Tesla Invader 2/3

The package succeeds Teslacigs’s style, adopting the hat box made of paper. In the front side there is printed the brand LOGO, name of the box mod, features of the box mod and the lateral view of box mod.

At the right side of the package box, there is the instruction picture showing how to change the battery.  At the left side, there is printed the words “powerful & simplistic INVADER 2/3”. At the back side, there is the product instruction information. The most information surely is the anti-fake label.

The content of the package is also very simple. There is only one box mod, a piece of battery cover for dual-battery scheme, a manual, a drawstring of battery, warning card and certification (Supplementary Instruction, there is protective film both for the box mod and the battery cover.)


Tesla Invader 2/3

Under the triple-battery mode, the appearance is similar to most box mods that adopt triangle layout to batteries, which is accorded with the ergonomic design on appearance and has very nice hand feel. On its design of appearance,  Tesla Invader 2/3 succeeds the style of Invader 3. It’s angular but is also featured with round curve. At both sides of the box mod, there is a “X”mark respectively, and at the lower part of the box mod, there is a piece of skin made of carbon fiber and the name  Teslacigs.

Tesla Invader 2/3

The fire button is settled at the upper part of the front side. Such design is very convenient for users to find the position of the fire button and gain a more comfortable usage experience. Below it is the adjust plate of the potentiometer and LED light.

Under the dual-battery scheme, the size of the box mod is compressed largely, but the comfortable hand feel is by no means lowered (even improved slightly).

Tesla Invader 2/3

Let’s make a comparison between Invader 2/3 under dual –battery scheme and its predecessor Invader 3 (the size of Invader 3 is relatively smaller among dual-battery box mods). Apart from that it’s much thicker than Invader 3, its height and length are both smaller than Invader 3. Regarding the color, Invader 2/3 has more choices for color and the color matching of each box mod is proper.


Tesla Invader 2/3

In the manual, there is the information of the unit resistance 0.1Ω and the corresponding output wattages at different gears, but there is no detailed information of output voltages. Here I will show you the data that I have tested with instrument.

Tesla Invader 2/3

In the pictures, you can see the voltage values at 1/3//5 gears under triple-battery scheme, first gear-3.08v, second gear-3.46v, third gear-4.15v, fourth gear-5.59v, fifth gear 8.29v ( rough data.)

Tesla Invader 2/3

In the pictures above, there are the voltages at 1/3/5 gears under dual-battery scheme, first gear 3.07v, second  gear 3.46v, third gear 4.27v, fourth gear 5.41v, fifth gear 8.06v (rough data.)


Tesla Invader 2/3

The workmanship of the battery covers in the package is pretty good, and at the two sides of the bottom, there are nine heat emission holes respectively.  Inside of the battery cover, there are circuit connection points (the battery cover under triple-battery scheme is connected by the batteries ). When the battery cover is not closed completely, the box mod will not be energized.

Tesla Invader 2/3

Under triple-battery scheme, the connection points of the battery cover and the connection points of the battery both adopt the treatment of silver plating, adding the current conveyance rate and the antioxidant ability.

The lock for locking the battery cover and box mod is very carefully designed. The battery cover and the box mod is connected by a groove structure. At the bottom of the box mod is the positioning structure of the battery cover which can well fix the battery cover. The integrating degree of the groove is pretty high without loosening or shaking.

Tesla Invader 2/3

The workmanship inside of the compartment is also impeccable. The elastic force of the silver-plated connection points and the circuit connection points are both strong with comfortable operation experience.

The 510 connection point is upgraded with a bigger contacting area which can improve the current conveyance rate, but the firmness of the paint is not so satisfying.

–Actual test—

Tesla Invader 2/3

I use the Geometry RDA tank to test the output, the data  as below: Kanthal A1 coil, wire diameter 0.6, circle diameter 3, 6 circles, 4 coils and the resistance is 0.12Ω.

Pictures above are the output test situations under dual-battery scheme at 1/3/5 gear.

Tesla Invader 2/3

Pictures above are the output test situations under triple-battery scheme at 1/3/5 gear.

From the pictures above, we can see the difference between dual-battery scheme and triple-battery scheme. Under triple battery scheme, the output is obviously more fierce than that under dual-battery scheme. By comparison, we can know that this box mod has a relatively big limit to the current (after all, the wattage calculated by a 8.29V voltage and 0.12Ω resistance can reach a horrible value of 572wattage ).


Tesla Invader 2/3

The operation mode still succeeds the style of the Invader series—click 5 times continuously to turn on the box mod,  and the LED display screen as well. The adjustment of output is also very easy and simple for using (Start from the lowest gear, if you think the output is too weak, you can adjust it to a higher degree; if you think the output is too fierce, you can adjust it to a lower degree.)

The adjustable voltage of this box mod is very user-friendly to the new players. With it, new players can control the time to adjust the coil when burning the coil.

Tesla Invader 2/3

If the paint can be much firmer with strong abrasion resistance ability.

The switch of the dual-battery and triple-battery is extremely easy. Users don’t have to disassemble the redundant battery on the battery cover, but just to change the battery cover.

Tesla Invader 2/3

Here I would like to revise a conception. We are used to call the VV box mod “semi-mech”box mod.

However, this is not always accurate. After all, at the very beginning, the semi-mech box mod was just added protective chipset on the mech structure, but was not really featured with the function to adjust the output voltage. Later, the box mod installed with potentiometer appeared and its voltage was adjustable.

But people are still accustomed to call it semi-mech mod. Actually, the voltage of it can be adjusted, so it’s not right to call it semi-mech box mod. The right way to call it is VV box mod.


Tesla Invader 2/3

To sum up, the output and workmanship of this box mod has made great improvements compared with its predecessor Invader. The only point needs to be improved is the paint.

On the other side, for those vapers who likes to DIY the appearance of the box mod, Tesla Invader 2/3 is a very good choice for them. The can easily erase the paint and then process the shell with customized treatment, making it more unique.

Personally, I like the box mods adopting potentiometer. They have the features such as fierce explosion, fast ignition, easy for adjustment. Thought it doesn’t has the TC function, it makes the best on the output voltage.

Tesla Invader 2/3 box mod will satisfy your vaping need well. You can totally enjoy 38% off if you make the purchase now!

Teslacigs Nano 120 Review—Succession and Transcendence of Steam Punk

Tesla Nano 120w

Recently, a newly released box mod—Tesla Nano 120w by Teslacigs has aroused hot discussion in the vaping world. Its steam punk styled gear with deep-carved texture pleases the eyes of vapers!

Tesla Nano 120w

Teslacigs Nano 120W does not adopt the common transparent Acrylic package but utilizes the paper box.  On the packing box, there is printed with the type of the mod, the picture, its Logo and decoration pattern of the gear at the two sides.  From the package we can see that Teslacigs company has made great efforts on this Tesla Nano 120w box mod.

At the back face of the packing box, there is printed with the features of the products, the packing list, warning content and anti-fake code as well as other regular content. The size of the bottom box is much smaller than the top lid which is convenient for opening.

The features of Teslacigs Nano 120w published by the official are as follows; Steam Punk Style, 120w output wattage, zinc alloy die cast, OLED display screen, dual 18650 battery, toggle switch,  various modes including TC-Ni, TC-Ti, TC-SS, TCR, KA, innovative flavor-control mode.

When you open the box lid, you can see there is a Teslacigs Nano 120W box mod, a manual in seven languages including French, German, Spain, Dutch, Italian and Chinese, a battery safety cue card and a factory certificate.

Me: er…why there is no USB cable in the package?

Tesla Nano 120w

Teslacigs:  What is that carton beside your leg? Are you a collection freak? You don’t have USB cable?  And, do you see any USB port on the Tesla Nano 120w?

Well, this is just for joking.

Tesla Nano 120w

That is true, there is no USB port on the Tesla Nano 120w. For charging, you have to take out the battery and to charge it with a charger.

At present, there are four color schemes released officially. What I show you here is the “antique copper” version. The reason why “antique copper” is in quotation mark is that the shell of the box mod is actually made of the material of zinc alloy and is processed into the color of “copper”.

By actual measurement, the size of the box mod is 89*55*24.5mm. Without batteries, the weight is 248g. With two batteries inside, the weight is 337g. Compared with other box  mods, Tesla Nano is very heavy in fact. It’s probably  one of the reasons why Tesla does not utilize the material of copper.

The battery compartment is designed at the bottom of the box mod. Such design is very fashionable at present and is adopted by many box mods.  The advantages are that such design will not destroy the overall shaping and is convenient for installing and disassembling the batteries. To open the compartment cover, you just press downward lightly and pull the cover at the direction indicated by the arrows.

Apart from the contactors at the bottom, the contactors inside of the battery compartment is also printed with the marks of “+”and”-”.

Tesla Nano 120w

Tesla Nano 120w adopts a brand new chipset scheme. In the light of the contents displayed and the layout, it is greatly different from the previous products.

The contents displayed on the screen include resistance, wattage, voltage, battery volume and other irregular contents including output “special effects”, coil material and memory modes.  You can tell from the pictures below that the function of Tesla Nano 120w is very abundant.

Tesla Nano 120w

After seeing so many functions, you may have worries on the settings.

Teslacigs Nano 120w has multiple functions, but the actual operation is very simple—press the fire button 3 times continuously to enter into the setting mode. By pressing the two adjustable buttons to move the highlights to the functions that you want to set and then press the fire button to confirm it. You can press the adjustable buttons to switch into different options and after you set it, you can press the fire button to confirm it and then exit the setting mode.

Apart from the regular output “special effects” including “Norm”, “Soft”, “Hard”, Nano 120w is also featured with the “User”(user-defined) output “special effect”, the so-called “adjustable output curve”. By setting differnt wattage outputs at different time to realize the “frequency conversion” output.

For example, when using fancy coils or huge vapor atomizers, you can set the wattage output a little high at the beginning. In this way the warming time of the coil will be shortened and the degree of output will be  improved.

Then you set the wattage back to the normal value to avoid the overheating of the coil, and accordingly to avoid burning of the coil and influencing the flavor of the oil.  At the end  you can set the wattage much lower.

Tesla Nano 120w

For example, at the beginning, you can set the output at 120w to warm the coil instantly, then you can set it at 80w to keep a normal output. After 1 second, you can set it at 30w-50w or even lower to avoid continuous warming and accordingly producing the flavor of burnt. At the same time, when you are going to end drawing, you also don’t need full wattage output to produce so much vapor. A lower wattage is enough.

However, this is just the regular method of“curve setting ”. Teslacigs not only has  adopted this function but also made improvements on it.

In actual test, I found that when setting the mode, if you want to set the output as the maximum of 120w, then you have to set the maximum output value at 120w before you enters into the “curve setting”. Or the maximum output wattage will in no way to surpass the wattage that is set at the stand-by mode.  Is this a BUG? Of course not, instead, it is a very practical function.

By the regular curve setting method, once the you change the atomizer or the resistance, you will have to change the curve setting. That is because 0.16Ω and 0.5Ω has different performance under 120w.

The method adopted by Tesla Nano 120w is very smart. As long as you set the output curve and as long as the mod is under the same usage status, for example, the atomizers you use are all RDAs,  or the atomizers you use are all huge-vapor atomizers, and they can all adapt to the gradually-declining output curve but the resistances are  different, then you just need to set the curve and adjust the total output wattage when using the Nano 120w.  The chipset will calculate the corresponding output values on the curve according to the total output wattage, and the shape of the curve will not be changed.

That is to say, as long as you set the curve that you are accustomed to, no matter what data or what atomizers you change into, you just need to adjust the total wattage at the stand-by interface, no need to set the curve again. The chipset will scale the curve in equal proportion according to the settled maximum output which is very convenient.

Apart from the innovation in its function, the performance of Nano 120w also succeeds the previous devices of Teslacigs’ in the  performance of “hard output”.

Tesla Nano 120w

Take a RDA for testing.  The resistance is around 0.16Ω.  I set 120W as the maximum wattage. The coil responds instantly to start working right after I switch on the box mod, and the degree of output is really strong.

The shape of the vapor reminds me of the “Invader III”. However, Nano 120w can reach such an effect by just 120w.  Obviously, the wattage of Tesla Nano 120w is really true to its name and even a little “modest”.

In actual use, the performance of Nano 120w is also the same.  The atomizers that I use on other mods at 70w to 80w, when use them on Nano 120w, I have to “lower the voltage” to 60w-70w.  Even under the “Normal”output mode, you can easily feel the explosion degree of it.

Especially when using the fancy coils at some other mods, users have to “increase the voltage” to shorten the time of coil warming. But when using the fancy coils at Tesla Nano 120w,  as long as the voltage is in the normal range from 3.7v-4.2v, it can have good performance. Sometimes, you even have to lower the voltage to hold it.

Of course, too hard flavor is not liked by every one. Vapers who don’t like too hard flavor can use the “Soft”output mode or “User”user-defined curve output mode to adjust the flavor.

Tesla Nano 120w

As regard to the design of the fire button, Tesla Nano 120w also succeeds the style of Teslacigs and adopts the big size button, of which the touch feel is very good.

The position of button forms roughly an angle of 45° to the horizontal line at the side. It is comfortable for using no matter your thumb or the index finger.

The Tesla Nano 120w also has a power switch.  Users don’t have to press five times continuously to turn on the mod, but only to switch it according to the direction marked on the body, which really simplifying the operation process.

The texture on the mod is processed into a very standard and fine condition. The fineness and the depth of the patterns are both improved compared with the previous Nano 100w. It not only has inner excellent performance, but also outer pretty appearance.

Tesla Nano 120w

The unique design of the appearance beatify the box mod a lot, but it brings troubles when choosing atomizers. The regular atomizers are not able to match this steam-punk styled box mod perfectly. Accordingly, I suggest that users consider either the texture or the material when choosing the atomizers.

Tesla Nano 120w

Users can choose the atomizers with finely carved textures, such as Maze V2 RDA ; or atomizers made of copper or of same color, such as Kennedy  , Coilart RDAs. Of course, if you have the same-styled atomizer, that will be better.


Tesla Nano 120w

I hope Teslacigs can develop an atomizer that can perfectly match Nano series box mods to satisfy the vapers who like steam-punk style.

Tesla Nano 120w

In summary, the workmanship of Tesla Nano 120w is much finer than the last generation Nano 100w. Also the built-in battery is changed into dual-18650 batteries which greatly improves the output performance of the box mod.

In the respect of operation, the display functions are various, but it’s actually very convenient for using and simplifying the setting process a lot.

The size of box mod is similar to the regular dual-battery box mod.  But when it has the batteries installed in the mod, the 340g weight will decrease the advantage of its portability.

Any way, different people think different. I think light weight material does not match Tesla Nano 120w with such an appearance.

In daily use, I found that the energy efficiency transformation of Tesla Nano 120w is very high. That is to say, it is very power-saving.

All in all, Teslacigs Nano 120w not only succeeds the steam punk style, but also transcends such style in some way. It’s not only excellent in its appearance, but also in its performance.

Recently, Cloupor Company showed its ability again to release a brand-new dual-battery high-power mod Smoant Charon. It features 218w maximum output and can be a threatening competitor to the high-power mods.

Today we will share with you the usage experience of this mod.


Smoant Charon TC 218

When you open the package, you can see the appearance and the name of the mod, and at the top right corner, it gives the color of the mod. At the back side, apart from the Logo and the model, it’s also printed with the features of the mod. At the bottom right corner, there is a anti-fake sticker.

When you open the package, the first thing into our eyes are manual, warranty card and the battery warning card.  Then you will see the Charon TC 218. Cloupor has released multiple color schemes for this mod. At the left side of the package, it’s the USB cable.

— Appearance–

Smoant Charon TC 218

It’s obvious that this box mod makes efforts on the ergonomics. The arc shape of the battery cover makes it comfortable to handle. Moreover, the front side is dealt with chamfering treatment.  The layout of the buttons is very even and is easy for operation.

The main part of the box mod is made of zinc alloy, thus it is inevitably heavy. Well, it’s normal for such a big size mod.


Smoant Charon TC 218

The diameter of the scratch-proof plate at the 510 thread is 22mm. The two loops are featured with radial patterns and the elastic force is very strong.

There are eight rhombic heat emission holes. At the back side of the battery cover, there are three ellipse heat emission holes on the top and at the bottom respectively.

The scratch-proof plate at the 510 thread is much higher than the plane of the box mod, which can effectively prevent the paint abrasion of the atomizer when installing the atomizer.

The inside of the battery compartment adopts the semi-open design. The straw string is for getting out the battery. There are four strong magnets to connect the battery cover and the body.

In each inner side, there is insulation sticker to lower the possibility of danger in case that the battery is peeled off (better not to use such batteries .)

The positive and negative contactors are both electroplated. The upper contactors are fixed and the other contactors are adjustable with elasticity, which is convenient for getting out the batteries.

We make a comparison of wattage between RX300 mod and Charon TC 218 mod. The data of the used RDA is as follows: A1 coil, 22g wire diameter, 3.0 coil diameter, 6 circles, quadruple coils and 0.11Ω. In the picture above, the respective wattages from the left to the right are 100,150 and 218.

According to the test, there is no obvious difference in effect when using 100w and 150w. There is nearly no firing delay and the explosion is very fast.  Under the maximum output 218W, the actual effect of TC218 is weaker than the RX300, but even under maximum output, the delay time is still not increased.

–Actual Test Experience–

Smoant Charon TC 218

After using for a while, the advantages of this mod can be summarized as below:

  1. The delay time is really short and can be hard to be felt in using.
  2. In daily use, the explosion is really rapid.
  3. The ratio of the size and the weight is proper and the hand feel is nice.
  4. The temperature effect is stable.
  5. Two batteries can ensure the using time.
  6. The operation is really easy and there is a manual in the package.
Smoant Charon TC 218


  1. The overall workmanship is just good.
  2. Under NC Temp Control Mode, the flavor sometimes become light (it’s the problem of the chipset and can be revised by the manufacturer later via PC end.
  3. The leather at the back side of the battery cover has the risk of being unglued in using.
  4. The anti-abrasion capacity of the cover of the box mod is not strong.


Smoant Charon TC 218

Dating back to the development of the mods, the wattage and performance of the entry-level box mod is increasing gradually, from 40w at the beginning to 150w at present. The problem of firing delay seems to disappear and the operation is becoming easier.

In summary, the performance price ratio of this Charon TC 218 is excellent. Its easy operation and wide wattage range can be the good potentials of this box mod to be the must have for entry-level using. Thought it does have some flaws, the advantages of its features and performances can well make up for them.
