GeekVape Zeus X RTA Review

GeekVape Zeus X RTA

The GeekVape Zeus X RTA is the latest release under the God of thunder’s name from GeekVape.

In a slight change to previous iterations, the Zeus X RTA offers both single and dual coil configurations and comes with a 4.5ml capacity.

It offers a leak-resistant design with its top airflow system, which has been reconfigured to allow air to hit the coils from the top and side.

The Good

Brilliant build quality, well implemented top airflow, easy to use build deck, excellent flavor, and vapor in dual coil mode.

The Bad

Not the best o-rings, the top cap is hard to grip, average single-coil performance.

The Bottom Line

If you are searching for a dual-coil top airflow tank, then the Zeus X RTA is by far the best on the market right now. The top airflow design system works well in delivering air to all parts of the coil in a smooth fashion, delivering excellent flavor. Can be used in single-coil mode, but there are better options for that sole purpose.

GeekVape Zeus X RTA

The Zeus X RTA as you’d expect shares the same external aesthetics as it’s predecessors with the customary Zeus face on the chamber. It’s not an ugly looking tank by today’s standards, and I’m actually quite digging the Red/Black mix of the one we have in for review.

The tank is a 25mm at the base, which then bulges out to 29mm with the use of the included bubble glass. The bubble glass gives the capacity a bump up to 4.5ml from 3.5ml of the standard straight glass. The Zeus X is undoubtedly one of those tanks that a bubble glass genuinely suits.

The Zeus X also sports the same easy release top-fill cap, which only requires a quarter turn to remove. It’s now a tried and tested method and also allows to keep the height of the tank down. However, there’s very little knurling so it can be a bit tricky to get a grip of the top cap at times.

One thing you will notice is the Zeus X comes with a remarkably low profile drip tip, which I think keeps it looking compact and sleek. Some may find it a little too small, but thankfully it is compatible with 810 drip tips, there’s also a longer Ultem drip tip included in the kit and a 510 adapter.

As standard from a GeekVape product, there’s a mass selection of accessories that come with the Zeus X RTA besides the drip tips. You get two nichrome tri-core fused Clapton coils, two shoelace cotton strips, a multitude of replacement deck screws and O-rings, and both the bubble and straight glass sections.

Build Quality

The build quality on the Zeus X is excellent as you would expect from a GeekVape tank.

All the threadings are super smooth, including the airflow ring, which also maintains the perfect amount of restriction. The top cap connects seamlessly, and the paint finish on all parts is exceptionally high quality.

The one slight negative is with the o-rings which feel a little loose, especially on the bottom glass section.

Build Deck9.0
GeekVape Zeus X RTA

The build deck in the Zeus RTA is quite similar to that of the Dead Rabbit but without the ears just two blocks. The post holes are at the top of the blocks, and the coils slot down from above, with the screws being tightened from either side.

So as you can imagine installing coils on the Zeus X Coil is quite straight forward. You just need to pre-cut the legs of your coils, then slot them down into the deck, and secure them with the flathead screws either side. There’s also a space to enable you to trim you coil legs underneath if you do have them a little too long.

The configuration of the posts also makes it easy to use either a single or dual coil. If you are using a dual coil setup, be sure to leave enough space between the coils.

There’s not a tremendous amount of room for large exotic builds due to the size of the chimney, but you should still be comfortable with anything 3mm internal diameter. It’s worth checking the chimney clearance on your first couple of builds.

Wicking is also reasonably straightforward, but as with other top-loaded decks, you do need to make sure the wicks lengths are quite long and reach the base of the deck. I will say it feels to be a little more forgiving than either of it’s Zeus siblings when it comes to wicking.

So overall it’s not the most innovative build deck, but it’s certainly an upgrade over both the original Zeus and Zeus Dual.

Airflow

This is where the Zeus has always been pretty solid, in my opinion, and it’s even better with the X RTA.

The Zeus X RTA uses a double chimney style setup, there’s one small chimney inside the other in the chamber (hence it’s quite a tight-fitting chamber to build deck).

The chimney on the inside has two small cutouts, which connect with notches on the build deck to help it stay in place when connecting everything together. The surrounding outer chimney has a small o-ring at the top to help keep it in place, so you do need to pay attention when unscrewing your build deck.

So this double chimney setup allows air to flow down and hit the coil from the top and from the sides, or in GeekVape’s words ‘direct top airflow and top-to-side airflow’.

With so many holes and directions of airflow, I was expecting the Zeus X to be quite turbulent. However, I was pleasantly surprised it’s actually incredibly smooth, and a lot quieter than either Zeus predecessor. It can also get quite airy when fully open.

Let’s start with the not so great part of the performance and end on a positive.

With the Zeus X RTA setup in single-coil mode, it becomes quite a noisy vape and the performance while still good, is not amazing. Now I did only use a 3.5mm ID coil in single-mode, I’m sure a 4mm would curtail some of the noise and probably deliver better flavor due to the restricted chamber.

However, this tank is at it’s best when it’s in dual coil mode. I tried a couple of different types of coils, including the tri-core fused Claptons included in the kit. My overall experience was pretty much the same with all of them, for a top-airflow RTA it delivers flavor and vapor on par with some of my goto bottom airflow RTA’s. The draw is incredibly smooth, and it’s a notably quiet for a top-airflow tank.

As a dual coil top airflow tank, the Zeus X is miles ahead of the competition and easily beats out Zeus Dual and Dead Rabbit RTA for flavor, and overall performance.

Good Vibes

  • Brilliant build quality
  • Looks good
  • Leakproof
  • Easy to build and wick
  • Intelligent top airflow design
  • Smooth airflow
  • Excellent flavor
  • Quiet for a top-airflow tank
  • Lots of accessories

Bad Vibes

  • Not the greatest o-rings
  • Quite compact build deck
  • Top cap hard to grip
  • Average single-coil performance

Verdict

I like what GeekVape have tried to do with the Zeus X RTA in creating a universal tank capable of single/dual coils with top airflow.

They have certainly achieved that with the design, and it’s a definite improvement over the Zeus Dual. The one caveat would be if you are looking to get the Zeus X and run it only in single-coil mode, there are far better performers out there like the Wotofo Serpent Elevate. But it is passable for the occasional single coil use.

However, when it comes to dual coil and top airflow, the Zeus X really shines and is quite possibly in a league of its own.

It delivers excellent flavor and vapor with a smooth draw, in a leakproof design.
