I really like the design of this tank. I’ve never been a fan of the way bubble tanks look, but Geek Vape made this one look pretty good. I think what makes it look better than others is the shape of the top cap and the base. The mouthpiece has this slant that leads into the tank, rather than being boxy and straight. But these angles create more of a roundness, so the size of bubble glass seems more subtle. And the base of the tank does the same thing, leading up into the tank at an angle.

As for the rest of the design, everything looks good. The finish for all of the colors look nice and I also like the low-profile style of the drip tip. On the chimney, you’ll see this very finely printed design of Zeus, the Greek god. That’s really cool. It’s a very nicely designed RTA as far as style goes.

It’s 25mm in diameter and it stands about 1.8 inches tall.

Drip Tip

The drip tip is a very short low profile tip. You also get an extra Ultem 810 drip tip in the box if you want something a little longer.

And of course, you can use your own on here too. And if you want to use a 510, there’s a 510 adapter in the box too.

Top Cap, Fill Ports and Airflow Control

The top cap unscrews from the top of the chimney-piece, right above the airflow control. There’s nothing interesting about it.

When you take that off, you get access to the fill ports.

This is a top airflow tank, so that should help prevent leaks. On the top cap is the airflow control ring, which comes off so it’s nice that you can remove it and clean behind it. The one problem with it though is that it’s just a little too loose and comes off really easily. But as far as adjusting it goes, it moves nice and smoothly both ways and comes to a stop at each end.

And of course, you have the silica glass tube, which is 4.5ml in the standard version. The 4.5ml glass is pre-installed, but you get a 3.5ml straight glass tube in the box if you want to use that instead. And I know some people really hate the way bubble glass looks, so it’s nice that you have the option to switch it up if you want.


The chimney on here is a double-chimney, which Geek Vape says creates optimal flavor.

The top chimney’s chamber covers the internal airflow chamber. That internal chamber is held inside of the outer chamber with an o-ring.

When putting this back in, you have to make sure that it’s lined up correctly. If you look inside the outer chamber, you’ll see the slots where the inner chamber is supposed to slide in.

You’ll also notice that this inner chamber has airflow holes. So when you take a hit from the tank, the airflow comes in from the airflow at the top, goes between the two walls, and is directed straight to the coils. It’s a really cool idea. The airflow on the Zeus X is super smooth, and I think this is one of the reasons. I also think this is helping with flavor production.

Build Deck

The Zeus X supports both single and dual coil builds, but the one thing you have to keep in mind when doing single coil is that you need enough cotton to fill the wicking holes so that it doesn’t flood. That means you need to build a pretty big coil. GeekVape recommends a minimum of a 3mm coil or bigger.

It’s a postless deck, so you need to cut the coils to the right length, drop them down into the post holes and tighten it all down with the pre-installed flathead screws.

I’m not really a big fan of postless decks because I can never get the coil legs snipped to the right length. I don’t have one of those coil measuring tools, but I should really get one. What do you all think about postless decks? Do you like them or hate them?

Anyway, there’s some space at the bottom of the posts that would make you think it would be easier to clip the leads once the coils are in, but that space is way too small to get the wire clippers in there. So you really do need to try to get the measurements right when you clip the leads before installing them.

When aligning the coils, you’ll want to make sure they don’t go past the edge of the posts.

The chamber isn’t very big, so that’s about as far as you want to go to prevent the coils from touching the chamber and shorting out.

The posts sit a little tall, so when you wick the coils, you’ll want to cut them just a little longer than the outside of the base. Then you just tuck that into the holes and do the other side.

Geek Vape does include two Ni80 0.4ohm Coil and some cotton, so you have what you need to get started.

Flavor & Performance

The flavor is pretty good. It’s not as good as a mesh tank, but to compare to other RTAs that I’ve used, this one is up there with the best of them.

The airflow is nice and smooth. With the airflow wide open, it feels good and you get a lot of air coming through. The flavor is good wide open, but it gets better the more you shut it down.

Final Thoughts

So that’s it for the Geek Vape Zeus X RTA. It looks good, the top cap is easy to take off to fill the tank, and the double-chimney airflow creates some really good flavor. The postless deck makes installing coils a little more challenging, but it’s not really a big deal. So yeah, I really like this one a lot.
