How do you follow up on a rebuildable tank atomizer (RTA) so dominant that you named it after the god to end all gods? You pretend it’s 1999 and add an “X” to the name. (Because, you know, that makes it even more “extreme,” right?) Introducing the all-new Geek Vape Zeus X RTA.


Just like the original Zeus, the Zeus X comes with a heavy handful of “leak-proof” claims. The original was pretty good in that department (because any top-airflow tank usually is) but the Zeus X seems altogether more solid and well-built, representing a nice forward step for the brand.

But why take my speculation about it? Here’s the official line on the Geek Vape Zeus X RTA.


The Geek Vape ZEUS X RTA is the upgraded rendition of the appraised Zeus series, deploying an elevated postless build design to accommodate a complex range of builds while improving upon the dynamic, performance-driven top airflow design. A culmination of little construction features from the previous edition, the ZEUS X 25mm RTA is crafted for ergonomic form factor that caters to the building enthusiasts with a quality top-fill mechanism and leak-proof top airflow structure.

A little shorter and squattier than its predecessor, the Zeus X is still a minimalist, bare-bones affair. The 25mm diameter tank is sleek, well-machined and has the innate ability to look good on any mod in my collection, regardless of which color you choose. Once again, Geek Vape’s sense of style is commendable.

Geek Vape Zeus X RTA Review – Spinfuel VAPEOne area I was hoping to see an improvement in is e-liquid capacity, but once again, the Zeus X has a maximum of 4mL, which is more like 3.5 realistically. Hardly a number we’ll thumb our noses at, but not exactly conversation-worthy, either. In an era of 8mL sub-ohm tanks taking over store shelves, the Zeus X seems a little spartan, capacity-wise. I understand that the larger-than-average build deck accounts for a lot of the space inside the tank, but this really could have been improved with a wider glass section, or a different deck size.


And that deck, well… expect to refill the Zeus X just as often as its big brother. Not only from the low capacity, but also because it’s one of the thirstiest tanks available today. The payoff is awesome flavor and competitive vapor, but don’t be surprised if your tank is NOTICEABLY lower, even after a few puffs. Stealthy and long-lasting, this ain’t.


Thankfully one of my biggest gripes about the original – the narrow, difficult to fill top port – was much easier to wrangle on the Zeus X. Not only is the port wider, to accept more bottle sizes, but the locking top cap was much stiffer and more reliable. If you don’t think this is a big deal, then you’ve clearly never had an original Zeus open on its own in your pocket – messy times, kids… messy times.

Geek Vape Zeus X RTA Review – Spinfuel VAPEStandout Features

Just like a rehash of the original review, the interior airflow design that channels air through a series of unique channels continues to eliminate gurgling and spitback when wicked correctly. Through all the RTAs I’ve tested over the years (and all the meaningless airflow gimmicks that came with them) this simple, logical design choice makes sense, and works seamlessly. Don’t be surprised if you confuse this performance with that of a prebuilt sub-ohm tank coil – with the right build, you’ll be set for ages.


However, unlike the original Zeus, the Zeus X is a much more capable atomizer, if you’re seeking the same flavor clarity, but increased vapor production. I managed to fog my office in record time using a simple, 0.4-ohm Kanthal build and some higher-VG liquids. Even wide open, the airflow never compromised flavor quality, making this one of the most versatile all-around RTAs in my collection.

Geek Vape has made a damn fine RTA here. Cloud fiends finally have an RTA to compete with their dripper arsenals. While flavor fiends will maintain their love for the series.  In fact, with the slightly squattier design, the chimney seems even closer to the widebore 810 drip tip, leading to mouthfuls of rich, warm vapor just dripping with flavor.


The deck is nearly identical to the original Zeus – a postless affair that does best with simple, uncomplicated builds. Just make sure there’s enough cotton (more than you’d usually use on an RTA) to prevent popping and gurgling, and you should be all set. I didn’t experience any dry hits or hotspots during my testing, no matter how hard I tried. The juice just seems to flow better on this deck than with most RTA designs.


Any complaints? The low-profile 810 drip-tip is barely tall enough to fit on the lips without getting some part of the chimney in your mouth. Some may tolerate that, but it can get uncomfortable during higher-wattage, chain vaping sessions. Just a spare millimeter or two would have made a world of difference for those seeking more comfort when puffing.


(Oh, don’t forget – bring LOTS of e-liquid with you, if you plan to bring the Zeus X out for the day. Don’t say you weren’t warned.)


– Yes, it’s pretty leak-proof

– Rich, nuanced flavor and strong vapor production

– Geek Vape’s commitment to universal styling is commendable



– E-liquid consumption is off the charts

– Short drip-tip can get uncomfortable

– Low capacity for a tank of this size

Spinfuel VAPE Recommendation and Score

What can we say? It’s a sense of deja vu! Sure, maybe there aren’t enough differences to call the Zeus X an evolution of the the original. But it certainly improves on every problem area we identified, making for a better all-around experience. With a nearly leak-proof design, wide-open deck and stronger vapor performance should put the Geek Vape Zeus X RTA near the top of any builder’s list for 2019.
