Design Features & Usability

The atomizer is actually consisting of 5 parts:

It is compatible with both 810 & 510 drip tips (the latter with the included 810/510 adaptor). There are two 810 derlin driptips, a regular one and an additional one which covers the upper rim of the top cap’s driptip-hosting base. This 810 driptip’s design is for protecting lips when temperature rises significantly.

The 510 driptip is of 10mm-heights, while the two 810 ones have about 7.5mm-heights. Aesthetics-wise, such small height is suitable for the size of the RTA, but functionally a bit more height would be necessary.

The top cap is removed with a slight rotation, revealing two fairly large holes for easily liquid-replenishing the tank with any bottle nozzle. The top cap perfectly seals the replenishment holes, not allowing the slightest liquid’s leakage.

The two replenishment holes are hosted at the upper part of a single metal piece, incorporating the airflow adjustment ring and a double-walled “bell”, which carries the air down to the deck, as it flows between the two walls of the “bell”. The actual vaporization chamber’s bell is the smaller internal one, which is domed internally at its top, for uniformly compressing (with less turbulence) the air to the driptip (increasing thus flavour).

The airflow ring (carrying a stopper) hosts two opposite-positioned quite large air holes and shallow notches, allowing a stable grip of the airflow ring for easily rotating/adjusting it.

The same hollow notches are hosted at the outer periphery of the base for an adequate grip of the base when screwing/unscrewing it from the rest of the tank.

The double-walled “bell” is screwed on the outer periphery of the deck, allowing the internal vaporization chamber’s bell to roundly air-seal the deck, but permitting the air to enter through the deck’s two large, opposite-positioned air-inlet slots. The air incoming to the deck through these air-inlet slots are sideways air-feeding the whole lateral cylindrical surface of the coils, if the coil-builds are properly setup on the deck.

The deck is a double-coil postless GTA-styled one, with four flat-headed screws for tightening the two coils’ leads, approached from the periphery of the deck. But, their flat heads are small and their slit is hollow.

The usual tricky part of using postless decks is how to adjust cutting the appropriate length of the coil’s leads. This appropriate coil leads’ length is necessary for positioning the coil to the appropriate height over the deck in accordance to its air-inlet holes. It needs some “getting used to it” or you need a tool if you’re inexperienced. However, such tool is not included in the packaging, as it is in the case of the Wotofo Recurve atomizer.

Geekvape Zeus Dual RTA Performance

The whole cooperative design of the “bell” and the deck ensures that, as the air enters from the airflow ring’s holes, it is first uniformly diffused between the two walls of the “bell” and then inserted to the deck through its two large air-inlet slots, hitting the two coils sideways.

This layout arrangement results in vapour production of substantial quantity and density, if two coils are setup. But, the available deck’s space for setting up two coils is limited and care must be taken to avoid touching the two coils together (if they are wide) or contacting to the air-inlet “bars” that form the deck’s air-inlet slots (if they are long). Two coils of 3.5mm outer diameter need special attention to be properly positioned. In the case of setting up a single coil, you should use a larger diameter pivot-core to wrap your coil for ensuring a large enough coil with an outer periphery that gets close enough to the air-inlet slots of the deck.

Check in the following photos the installation of two 3mm inner-diameter Clapton coils of 0.2Ω total resistance (best operated at 60W-70W), making clear that a novice builder should wrap two coils of a 2.5mm diameter pivot-core.

However, coils should not be wrapped around a smaller than 2.5mm-diameter pivot-core, for ensuring that enough cotton can be tightly stuffed inside the coils (for increased capillary action – Bernoulli Effect), when the wick’s tails are touching down to the bottom of the base’s well. In this case, no combing of the wick’s tails is needed, but they should properly fill the wick’s holes of the deck. Such a setup presents no issues of wick’s liquid saturation.

The produced vapour is rich and, regarding its temperature, is cool to lukewarm. Quite satisfactory is the flavour’s intensity, balanced with flavour’s integration. The result is a vaping experience memorable for the provided taste, and the smoothness and quietness of the provided puff.

The atomizer doesn’t get too hot, even under chain vaping for long.

Liquid consumption is par with the dual-coil RTA’s category.

All in all, it’s an RTA of a premium build quality, functionality and performance. It is more suitable for experienced vapers.



I am not in the vaping business. I found vaping as the escape door from my 25 years of smoker’s imprisonment. It just took me four days of attempting to totally get out of it, thanks to the appropriate –for me- “equipment” (includes e-liquids). Now, vaping “equipment” has become another one of my fields of interest, for helping others to discover, on their own, their personally appropriate “equipment”.
I am a hands-on enthusiast… by genes. I am triggered by everything that evokes any data already stored in my knowledge base, been a Physicist and an Electronics Engineer (for more than 35 years). I am intrigued by everything new that my knowledge-filter considers interesting enough to be analyzed for entering into my memory compartment. That’s why you will find me open-minded and out-of-the-box thinking. I have an urge for unfolding hidden “pictures” of design thinking on everything man-made.
