GeekVape Zeus X RTA Review – It Really IS A Cracking RTA…Literally!

The Zeus X RTA by Geekvape Is The Last Of The Trio – So Is It Best Out Of Three?

The GeekVape Zeus X RTA is the last in the release of the tanks carrying the thunder God’s name so has the popular series gone out with a bang?

This is both a single and dual coil tank with a 4.5ml max capacity for everywhere except the UK and Europe – where thanks to the TPD we get the 2ml. The good news is larger bubble glass can be bought and as you’ll see below others do fit.

geekvape-zeus-x-rta-review

I’ve reviewed all three of the Zeus RTAs – the original Zeus which many felt was a bugger to wick and could give dry hits and the Zeus Dual which I enjoyed immensely. In between those releases was the Themis RTA which was all things considered a pretty decent vape.

OK this was sent to me free of charge for the purpose of review – thank you – and as always my thoughts and opinions are my own.

For the record I used the coils and shoelace cotton included – and also swapped for my own – and vaped on the flavorsome Puris from 12 Monkeys Origins and Raspberry Punk Grenade from Riot Squad.

Key Features

This is the third and final reiteration of the Zeus series of tanks and whilst GeekVape says the tank is 25mm at the base it’s slightly less than that and can be used with a single or dual coil set-up.

The rest of the world gets a 4.5ml capacity [with the bubble glass] and 3.5ml with the straight – whilst the EU and UK will get the TPD friendly 2ml versions. The one I’m reviewing is the larger one however the good news is the bubble glass can be bought separately.

Also if you have the Zeus Dual that bubble glass fits as does the one from the Kylin 2 RTA. I’ll mention the included bubble glass later…

geekvape zeus x review

This is both top to bottom and side to bottom airflow and there’s the addition of an internal airflow chamber – which has 14 ‘honeycomb’ style holes on both sides and there are two airflow ports.

The post-less style deck has had a major facelift too and looks cleaner – if a little tight in there. BTW if you don’t have a Coily tool the Zeus X RTA has a Dead Rabbit RTA / RDA style gap where you can get under to snip your legs – it’s a bit tight but can be done.

In the Zeus Dual RTA [the second] those ‘airflow arms’ shrank massively and now have completely gone to be replaced by two notches that line up with that internal airflow chamber – this obviously keeps the coils perfectly placed with the air input.

It’s more a genesis style deck and the wicking channels are shared and are a wee bit wider than in the Zeus Dual which for me made for much easier wicking.

More on building and wicking the Geekvape Zeus X RTA later.

Once again this is a top fill with a half twist bayonet style which opens up to show two smallish kidney shaped ports. A couple of juice nozzles have been a little too big to fit nicely however most I tested have been OK…

Design and Build Quality

This is definitely the best looking of the three Zeus RTA’s by a long way. It’s almost the same height as the previous versions but due to the design – and that ultra-low profile drip tip – even with the straight glass on it looks smaller and sleeker…eyes can be deceiving!

Thankfully they’ve removed that hideous printed company logo from off the top cap and the engraved Zeus from the base. We still have the Zeus logo on the barrel and on the reverse Zeus is now etched making the whole thing look much cleaner from a design point of view.

I really – I mean really like the way this one looks especially with the bubble glass attached.

Build Quality

All the moving parts – and there are a lot of them – come apart easily enough straight out of the box. A little over two weeks in and the airflow ring is still stiff and at times you can unscrew the whole tank whilst moving it and indeed unscrewing the top cap to fill..

Speaking of unscrewing and screwing – the knurling isn’t the most ‘grippy’ for want of a better word – especially at the base. To be honest I’d rather have that than over emphasized tractor tyre style from a design point of view…

The machining is as you might expect from GeekVape – on the better side of good though the base of the deck is a bit messy but hey you don’t see that.

Silica Bubble Glass – Cracking Under Pressure?

I’ve been using both Puris from 12 Monkey’s Origins and Raspberry Punk Grenade from Riot Squad…neither of which you could call the most citrus flavours out there.

However, as you can see from the photo of 3 fills of the Puris, the glass has cracked. I haven’t dropped it or knocked it over – it appears to be that chemical reaction some citrus juices have on many polycarbonate plastic tanks out there…I’m no chemist so does this happen with silica glass? Let me know in comments!

cracked zeus x rta tank
crack!

One thing I am sure of is it’s a bit annoying as no other RTAs in my rotation has done this with my go to e-liquids and touch wood neither has the straight glass included in the box.

I do need to point this out should you be vaping on citrus/fruit juice whilst out and about. BTW I haven’t seen any other reviewers with this issue so maybe mine had a fault? Who knows…

How Does the GeekVape Zeus X RTA Perform?

Zeus – Zeus Dual – Zeus X Compared

As with most ‘new editions’ of pretty much anything you expect the next gen to improve on the previous.

In this case GeekVape has definitely done that…by how much we’ll see at the end. For now let’s look at build and wicking.

Building on the Zeus X RTA

I used the included coils and cotton and the coils ohmed out at 0.17ohms.

coils n cotton

First up and I didn’t like the flathead screws – very small but luckily my screwdriver just about fit.

Rather than snipping the coil legs Dead Rabbit style from underneath – I used the Coily tool and for the first build opted for a conservative 3.5mm.

zeus x deck

After clamping them in and holding the internal air chamber next to them I felt they could do with another mm and lifted them slightly…

After a couple of builds I finally settled on 4.5mm finding this gave me a little more of a flavour pop. It’s obviously up to you how big or small you snip your coils and if I’m brutally honest that flavour pop might just have been in my mind lol.

coily tool zeus x rta

BTW I don’t have any fancy big ass coils and after popping one of my small pre-made 3mm ones I could instinctively see I was gonna get too much airflow so drowning out the flavour. Other reviews are out there using large coils in single mode…

The build experience was – for me as a fingers and thumbs type of bloke – a little fiddly but nothing too serious…though I now see why GeekVape says this is one for the RTA enthusiast…plenty of options to try…

Wicking on the Zeus X RTA

Less is more once again folks!

It’s definitely easier to wick than the original – remember that S Bend you had to make! And for me it’s definitely much easier than the Zeus Dual.

The ports are still shared but much wider and please note that’s NOT to say you need to stuff them full of cotton.

zues x rta wicking

I thinned my tails out and let them fall into the well – barely passing the edge if that makes sense. There’s really no need to have that cotton anywhere near the base put it that way. Make sure it’s at least half way down but preferably less. I think the pro’s call that the dam method…

For the record I’ve had zero dry hits and absolutely NO leaking…

Flavour and Vapour Off the GeekVape Zeus X

First vape was impressive to say the least and as those coils and cotton broke in it just got better.

The flavour off my two go to e-liquids was close to and almost as good as my juice review dripper the Augvape BTFC…and when I say almost I mean almost and that’s using the coils ‘n wick out of the box.

Airflow half closed and you get a lovely rich flavour and dense vape that really does cloud out your room – so the balance between cloud and flavour chasers is almost spot on.

zeus x rta firing

Wide open and trust me this thing is foggier than Skegness beach in February…and that’s foggy lol…

I changed the included coils for those Wotofo dual claptons I like and used FUZZ cotton to wick and again it could be my brain playing tricks but I felt the flavour was a little crisper.

zeux x rta wicks well
wicks well!

I do have to say when I first saw the Zeus X RTA I did think the low profile drip tip would be uncomfortable. I can assure you it isn’t in the slightest and I actually love it. Other 810s do fit but it’s a bugger to get off!

I reckon with a bit of fiddling with coil placement and choice of cotton you will keep on eking out that bit extra flavour…so yeah definitely one for the tinkerers – or should I say RTA enthusiasts out there 

Pros

  • Dual or single build
  • Great design
  • Clever airflow system
  • Great flavour
  • Great clouds
  • Relatively easy build
  • Dead easy to wick
  • Plenty of accessories

Cons

  • A tiny bit noisy
  • Bubble glass cracking with citrus juice…maybe?
  • O ring on the base apparently loose on some tanks – mine isn’t…yet!
  • Smallish fill ports
  • Whole tank has unscrewed when opening top cap a few times

Final Review Verdict

I was hoping / looking for major improvements from the Zeus X RTA and I’ve pretty much got it.

The deck is easy enough to build on though I think it’s quite tight in there. However if wicking was easy enough in the Zeus Dual it’s a cinch in this one – just remember don’t stuff it in…as I always used to say to the ladies… ‘less is more’ 

Flavour wise it’s most definitely improved and by quite a bit. Put it this way this one is now my go to RTA – alongside the Blitz FP and Reload and that says it all. Vapour is awesome – simple as that.

I’m just a little annoyed at the bubble glass cracking – especially as I’ve treated it with kid gloves so I can only assume it’s down to the citrus?

Apart from that unlike others out there I’ve had no issues with that wandering O-ring on the base and apart from minor issues – OK it can be a little noisy – on the whole I’m really enjoying this one to say the least.

So yeah…the Geekvape Zeus X RTA is definitely all it’s cracked up to be – let’s hope my bubble glass was faulty.

Highly recommended and is definitely in my top 3 RTAs of all time…
