Zeus tank | the Geekvape range in chronological order

On a vape shop shelf, a single name can hide several quite different products. The Zeus tank from Geekvape covers several generations released since 2017, rebuildable or fitted with ready-made coils, with capacities and diameters that change from one listing to the next. This summary puts the range back in order, cross-checks what retailers publish and points out where their figures disagree.

Zeus tank, what the name covers today

A Zeus tank is a Geekvape atomiser built for direct lung vaping, an open draw that takes the vapour straight to the lungs. Two branches sit under that name, and they are not used in the same way.

The first gathers the rebuildable tanks, or RTAs, on which the user fits the resistance wire and the cotton by hand. The second brings together the sub-ohm tanks, running below 1 ohm with factory-made coils that are simply swapped when worn.

Recent catalogues shorten the name to “Z”. A listing titled Z Subohm, Z Max or Z Sub-Ohm SE therefore belongs to the same family, and it is the exact generation, more than the name, that decides which coil to buy.

A range that started as a rebuildable in 2017

The range grew in several stages, from rebuildables to pre-built coil tanks, with one common thread that most of the listings read for this summary highlight, an airflow placed at the top of the tank.

2017 and 2019, the Zeus RTA and the Zeus X

Reviews published by Vaping Post date the first two milestones. The Zeus RTA, reviewed on 27 October 2017, is a single coil rebuildable of 25 mm holding 4 ml, with top airflow adjusted against a stop. Its atomising bell carries an engraving of the head of the Greek god, which gives the name of the range a literal meaning.

The Zeus X RTA, reviewed on 13 May 2019, moves to a dual coil postless deck, with no posts, where the coil legs are clamped directly. It keeps a 25 mm diameter and offers 3.5 ml with a straight glass or 4.5 ml with a bubble glass.

The Zeus Sub-Ohm, the switch to pre-built coils

With the Zeus Sub-Ohm, the range leaves coil building behind. Two retailers agree on its specification sheet, with a 26 mm diameter for 42.5 mm in height, 5 ml with the bubble glass, top filling and an 810 drip tip, a wide mouthpiece suited to a direct draw.

The box holds two mesh coils, the Z1 at 0.4 ohm rated from 60 to 70 W and the Z2 at 0.2 ohm rated from 70 to 80 W, the latter fitted as standard.

The 2022 SE edition and the Zeus 5

The SE version, described by one retailer as a 2022 edition, rises to 5.5 ml and adds a locking latch, which Geekvape says to press before turning the filling cap to the right. Two listings supply it with a Z coil of 0.15 ohm rated from 70 to 85 W.

The Zeus 5, also listed as Zeus Sub-Ohm 5 or V5, stands 56.1 mm tall with a standard 5.5 ml tank and a 7 ml bubble glass, and ships with Z XM coils of 0.2 and 0.4 ohm, according to two listings that match on these points.

Coils, the real dividing line inside the range

The coil is the part that heats the e-liquid and wears out. Across this range, it separates the generations far more clearly than the name printed on the box.

Z coils, now sold as the XM Boost version by the catalogues that add “formerly Z Series”, fit the Zeus Sub-Ohm, the Z Fli and the P Sub-Ohm according to two retailers. Their values run from 0.4 down to 0.15 ohm in mesh, a metal lattice that heats across a wide surface.

The Z Max opens a separate branch. Two retailers list it with M coils of 0.14 and 0.2 ohm, a different family. A listing that does not name the coil family therefore gives no way of knowing which pack to reorder.

Power ranges add a further doubt. The same 0.4 ohm coil is rated from 60 to 70 W on several listings and from 50 to 60 W on others. Geekvape itself publishes both, 60 to 70 W on the original Zeus Sub-Ohm page and 50 to 60 W on its current Z coil page, so the range printed on the coil box remains the reference.

Why a Zeus tank sold in the UK holds 2 ml

The 5, 5.5 or 7 ml shown on listings describe the manufacturer’s standard version. The Tobacco and Related Products Regulations 2016 cap refillable tanks at 2 ml in the UK, and a Zeus tank on a British shelf has to stay within that limit.

Some boxes therefore include a short glass for the compliant version, known as TPD. Two retailers mention a 2 ml glass supplied with the Z Max. The same rules limit nicotine e-liquid to 20 mg/ml in refill bottles of 10 ml, as our file on how British rules shape the T-Juice catalogue explains.

A listing that quotes only the standard capacity says nothing about what will be delivered, and only the list of box contents settles the point.

Diameter and capacity, where the listings disagree

Retailer listings copy figures that do not always measure the same thing, as three examples show.

The Zeus 5 appears at 24 mm in diameter on one listing, which also gives it a 29 mm width, and at 26 mm on another, while Geekvape’s official store gives a 29 mm width. A listing for the SE edition explains the gap, with 26 mm at the base and 29 mm at the bubble glass. For the Z Max, one shop states in a reply published under its listing that the 33 mm quoted by some buyers is the width at the bubble glass, while the base stays at 26 mm.

Capacity drifts as well. The same Z Max is listed at 4 ml by one retailer and at 6 ml by another, with neither mentioning a second version.

The gap matters for the mod, the battery device the atomiser screws onto, because the base diameter is what tells you whether the tank overhangs the top plate.

What to watch on the range

Three points deserve attention in the coming months. The move from the Zeus name to the Z name continues across catalogues, and both still sit side by side on listings that are sometimes old.

Coil names shift too, and the “formerly Z Series” wording shows that one pack can change its label. Then there is capacity, which too many listings still give only in its standard version. The pattern is familiar from other hardware, as with the changes on the Vaporesso Luxe range, where a new generation keeps most of its architecture.

FAQ

These questions come up around the range without being covered above.

How do you change the coil on a Zeus sub-ohm tank?

Wait for the e-liquid to settle below the wicking ports, unscrew the base, pull out the used coil and push in the new one. A few drops on the exposed cotton, then a few minutes of rest after filling, prevent firing a dry wick.

Which mod suits a sub-ohm tank from this range?

A variable wattage mod able to go beyond the power printed on the chosen coil, with a top plate that takes a 26 mm base without overhang.

What build goes on the Zeus X RTA?

The postless deck takes two identical coils, trimmed to the same length. Its final resistance depends on the wire and the number of wraps, and is checked on the mod’s ohm reader before the first fill.

Can nic salts go in these atomisers?

Listings consulted for this summary point these atomisers towards e-liquids high in vegetable glycerine, suited to higher power. Nic salts are usually meant for pod kits with a tight draw and low power.

Why does a Zeus atomiser leak?

The usual causes are a damaged or badly seated seal, a coil not pushed fully home, or an e-liquid too thin for a wick designed for thicker blends. Top airflow reduces leaks through the base without ruling them out.

Zeus tank, read the generation before the listing

The Zeus range has followed a clear path, from the 2017 rebuildable to tanks running Z XM and M coils. What makes it confusing lies mostly in the listings, which mix names, diameters and capacities.

Before any purchase, three markers are enough to identify a Zeus tank, namely the exact generation, the coil family and the base diameter. Following those markers over time also shows how the hardware market renews its ranges without changing their names.
