Geekvape Zeus tank: the name UK shelves kept
Ask for a Geekvape Zeus tank in a British vape shop and you may be handed a box with a different name printed on it. Zeus is still what customers say, still what they type into a search bar, and still what several retailers put in their page titles. The manufacturer moved on from the word some time ago. That gap between the shelf and the catalogue is the most useful thing to understand about this hardware, and it explains most of the confusion around it.
Why the Geekvape Zeus tank now answers to two names
Geekvape renamed the Zeus range to the Z Series. The hardware lineage did not change; the badge did. British retailers, faced with customers who still search the old word, resolved the problem by using both at once.
The result is visible across UK listings checked in August 2026. Vape Club titles its page around the Zeus tank while describing the Z tank underneath. UK Ecig Store sells “Z Series (Zeus)” coils. Geekvape’s own shop page for the current tank carries both words in a single product name.
None of this is careless. It is a search decision: the old name still carries the traffic, the new name is what is stamped on the box. A shopper who does not know that a Geekvape Zeus tank and a Z Sub Ohm tank are the same lineage will read two catalogues as though they were two different products.
The practical rule is short. Treat Zeus as the family name and Z as the current label, then check the generation rather than the badge.
Why the British word is vape tank, not clearomiser
The category heading on almost every UK retailer is “vape tanks”, with sub-ohm tanks as the sub-heading. Clearomiser survives in older writing and in translations from other markets, but it is not the word a British shop assistant reaches for.
That matters for more than vocabulary. The British filing system splits hardware by draw and by connection rather than by tank construction, so a sub-ohm tank sits with other direct-to-lung hardware that screws onto a mod, away from the closed pods.
A Geekvape Zeus tank belongs firmly on that side of the line: a 510 fitting, a replaceable coil pushed into the base, and an airflow ring meant to be opened rather than closed down.
What the 2 ml cap does to the Geekvape Zeus tank
British rules cap a refillable tank at 2 ml and nicotine-containing e-liquid at 20 mg/ml. Every UK listing for this family reflects that: Vapouriz, Vapestore, Vape UK and SMKD all show 2 ml versions and nothing larger.
Specification sheets written for other markets tell a different story. Geekvape’s international page lists replacement glass in several sizes, the largest well above the British ceiling, with the 2 ml version marked separately as the regulated one. A refillable tank advertised at 3.5 ml or 5 ml is simply not the version sold here.
That is worth spelling out because the gap changes how the tank behaves rather than just what it holds. A direct-to-lung tank run at the power its coils are built for gets through a 2 ml fill quickly, so the figure that decides whether this suits you is refill frequency, not capacity.
Anyone comparing a 2 ml British tank against a foreign review filmed with a larger glass is comparing two different daily routines. The hardware is the same; the experience of living with it is not.
Which coils fit which generation
This is where the rename does real damage. Z Series coils are the renamed Zeus coils, and UK retailers are consistent that they remain the platform for the Zeus and Z sub-ohm tanks. They are a push-fit design, seated by lining up two metal tabs with cutouts in the base, rather than threaded in.
They are also listed as the coil family for several Geekvape kits sold here, including the Aegis Legend line and the Z200. Vape UK, Wizard Vape and Ecigone all describe the same platform, which is enough agreement to state it plainly.
The exclusions are just as firm, and they are the ones people get wrong. Vape UK states that Z coils do not fit the Z Max tank, which takes M Series coils, nor the Z Nano 2, which takes B Series. A tank with a Z on the box is not automatically a Z coil tank.
There is a second layer inside the platform itself. The older Z coils have largely been replaced in British stock by XM and XM Boost versions, sold under the same Z naming. They are not presented as interchangeable in performance, so the version printed on the sleeve is worth reading before reordering out of habit.
Reading the generations without a catalogue
Several tanks in this family have passed through British shops, and knowing which one you are holding is more useful than knowing the family name. The original Zeus sub-ohm tank is now marked discontinued by some UK retailers while still being listed by others.
Above it sit the Z Sub Ohm SE, a simplified version still widely stocked, and the Z Sub Ohm Tank 5, the current one, sold around the XM Boost coils and a push-to-open filling system. The Z Fli sits alongside them with a flip top cap.
Buying a coil for the family rather than for the specific tank is the common failure here, and the rename makes it likelier. The safest habit is to buy consumables from the tank’s own product page rather than from a search for the brand.
Where it sits, and what powers it
A tank of this kind is only half a device. It needs a mod with a 510 connection, which puts it in a different part of the market from the sealed pods that arrive complete. Our piece on the Voopoo Drag X3 covers the single-cell tier that most often ends up underneath one, and the Lost Vape Centaurus M200 piece covers the dual-cell tier above it.
If that sounds like more device than you want, the ground below it is well covered by fixed-battery kits such as the Vaporesso GTX One, where nothing is removable and nothing needs pairing.
Where removable cells are involved, the numbers matter and none of them should come from an article. The usable power band is printed on the coil itself, and the current a cell can deliver comes from that cell manufacturer’s own published data. Treat any third-party figure, including a shop listing, as a starting point for checking rather than as an answer.
Who this tank is actually for
The buyer this suits already owns a mod and knows why. The 510 fitting is the point: it separates the tank decision from the battery decision, which is exactly what a closed pod refuses to do.
The buyer it does not suit is the one looking for a tighter, cigarette-like draw. This is airy hardware by design, and narrowing the airflow ring on a direct-to-lung tank produces a compromise rather than a conversion.
Between those two, there is a large group who would be better served by knowing the coil situation before the purchase than by any performance claim. Consumables decide how long a tank stays usable, and on this family the consumables carry two names and three sub-versions.
Frequently asked questions
Is the Geekvape Zeus tank the same as the Z tank?
They are the same lineage. Geekvape renamed the Zeus range to the Z Series, and UK retailers use both words, often on the same page, because customers still search for the older one.
How much e-liquid does the UK version hold?
Two millilitres. British rules cap refillable tank capacity at 2 ml, so any listing quoting a larger refillable capacity is written for another market.
Do Z coils fit every Geekvape tank with a Z on it?
No. UK retailers state that Z coils do not fit the Z Max tank, which uses M Series coils, or the Z Nano 2, which uses B Series. Check the tank, not the letter.
What is the difference between Z, XM and XM Boost coils?
They are successive versions of the same push-fit platform, with XM and XM Boost being the later ones now dominant in British stock. Read the version on the sleeve rather than assuming a repeat order matches.
What nicotine strength can be used with it?
Up to 20 mg/ml, the British legal maximum for nicotine-containing e-liquid, whatever the hardware. Direct-to-lung tanks are typically used with lower strengths than that ceiling.
What the naming tells you about the market
The Geekvape Zeus tank is an unusually clean example of something that happens across this industry: a product outlives its own branding because customers refuse to update their vocabulary. Retailers follow the customer, manufacturers follow the catalogue, and the two records drift apart until a shopper is left comparing what looks like two products.
Nothing about the hardware requires that confusion. The tank is a 510 sub-ohm tank, sold here at 2 ml, running a push-fit coil platform with clear exclusions and three generations of coil sleeve. Once the badge is set aside, everything that decides whether it is the right purchase is written on the coil box rather than on the tank.
