# Zeus vape tank: the whole GeekVape family > Where the GeekVape Zeus vape tank came from, why the range is now called Z, and how its coils travel as far as the Aegis kits on the UK market. Zeus Sub Ohm, Zeus Max, Zeus Nano, then Z Nano 2, Z Nano 3, Z Nano MTL, Z Subohm Tank 5, Z Fli. One family of reservoirs changed its name halfway through, and both naming schemes still sit side by side in British catalogues. Behind that apparent mess, the logic of the **Zeus vape tank** range is among the clearest on the market, provided you pick it up by the right end. ## The Zeus was rebuildable before it was a tank A starting point often forgotten: Zeus first named a rebuildable atomiser from GeekVape, the kind you build yourself with wire and cotton. The Zeus Sub Ohm Tank is the tank version of it, meaning the declination running prefabricated coils. That lineage explains the behaviour of the whole family. This is a sub ohm reservoir, designed for vapour production and direct lung inhaling, with the generous capacities that go with that use abroad. Sub ohm here simply means coils rated below 1 ohm, often well below. So it is neither a versatile reservoir nor a tight draw format by default. It is an object built around a capable mod and a liquid to match, and it does not pretend otherwise. ## What the letter Z replaced At some point in its history, GeekVape shortened Zeus to Z on new references. The Zeus Nano became the Z Nano 2 then the Z Nano 3, the Zeus Sub Ohm gave way to the Z Subohm Tank 5, and new branches such as the Z Fli or the Z Nano MTL appeared directly under the single letter. No technical break corresponds to that renaming. Older models are still supplied with coils, and British retailers keep using both names, sometimes on the same listing page. In practice, a search for a **Zeus vape tank** has to be widened to the Z references to cover the real range. That is the first trap in this catalogue, and much the easiest to avoid. ## The two current branches The family splits today on one readable criterion: the volume it targets. On one side the higher capacity reservoirs, on the other the reduced formats. The Zeus Sub Ohm Tank and its successor the Z Subohm Tank 5 sit at the top of the range, with direct lung inhaling as an assumed orientation. The Zeus Max goes further still, running coils from the M family quoted at 0.14 and 0.2 ohm. These references want a mod able to keep up, and they mount classically on the brand's Aegis kits, including the Aegis Legend and the Aegis Solo. The Nano branch takes the opposite path. The Z Nano 2 accepts a direct or an indirect draw depending on the coil fitted, the Z Nano 3 keeps that dual orientation, and the Z Nano MTL commits to the tight draw alone. It is the branch that has moved most, and it bridges the original sub ohm world and a lighter daily use. ## What British capacity figures actually mean Every capacity quoted for this family internationally, whether around 3.5 ml, 5 ml or 6 ml, describes a version that is not sold here. Under the Tobacco and Related Products Regulations 2016, administered by the MHRA, tanks sold in the United Kingdom are restricted to a capacity of no more than 2 ml. The brand's own product pages acknowledge it, listing replacement glass in several volumes with a 2 ml option marked as the compliant one, and British listings for the Z Sub Ohm Tank 5 state a 2 ml capacity outright. The same regulations cap nicotine containing e-liquid at 10 ml per refill container and at a strength of no more than 20 mg per ml, and require notification to the MHRA before sale. On a sub ohm reservoir emptied quickly, that 2 ml ceiling is the single biggest practical difference between a British setup and a review filmed elsewhere. ## The coils, the real entry point to the range This is where the catalogue becomes genuinely structuring. GeekVape does not run one single coil family through the Zeus tanks but several, and they do not cover the same models. - Z coils: for the Z Subohm Tank 5, the Zeus, the Z Fli and several Aegis kits. - M coils: reserved for the Z Max Sub Ohm. - B and B V2 coils: for the Z Nano 2 and Z Nano 3, and for Aegis Boost kits. - B MTL coils: for the Z Nano tanks used in a tight draw, including the Z Nano MTL. One detail rarely mentioned on a listing is worth knowing: the coil value conditions the liquid to use. The lower the value, the thicker the liquid it wants, and the exact minimum proportion is printed on the coil packaging by the manufacturer. A liquid too thin on a very low value coil produces flooding and a degraded result. ## Cells, power and how to read a datasheet A sub ohm tank on a removable cell mod raises a question the tank listing never answers. It is worth settling before the first fill, not after. The only reliable information about a cell is the manufacturer's own datasheet for that exact reference. It states the chemistry, the rated capacity, and the continuous discharge rating, and those figures belong to that cell alone, not to the format or to the colour of the wrap. Read the datasheet, compare it against the range printed on your coil and the specification of your mod, and let the lowest of the three govern what you do. Check the wrap too, since a torn plastic sleeve exposes the metal body and must be redone before the cell goes anywhere, and never carry a loose cell against keys or coins. ## Top airflow, the signature of the family Zeus reservoirs share an air intake located in the upper part of the tank, presented by the brand as limiting leaks while preserving flavour. On a reservoir carried around all day, the argument is not cosmetic. That choice has a mechanical counterpart. Air travels a longer path before reaching the coil, which explains the generous air sections on these models compared with a bottom airflow design. It also imposes a precise gesture at filling. Leaving a little air in the reservoir rather than filling to the brim avoids the pressurisation that pushes liquid up the chimney, and that habit alone removes most reported leaks. ## Living with a Zeus vape tank Two habits cover almost all of everyday use. The first concerns priming, the second the replacement rhythm of the consumable. Coils in this range hold a substantial amount of fibre. After filling, waiting around ten minutes before the first puff lets the cotton soak through completely, and rushing that step is the most common cause of an early burnt taste. On replacement, retailer guidance tends to quote a few weeks as a rough marker, noting that the lowest values wear faster. Treat any such figure as indicative: applied power and liquid composition weigh far more than the calendar, and the real signal is the decline in flavour. Checking the seals at each change heads off most leaks. ## FAQ ### Is this range suitable for a tight draw? Only on the references built for it, such as the Z Nano MTL or a Z Nano fitted with a B MTL coil. The Subohm models stay oriented towards direct lung inhaling. ### Can a Zeus go on a mod from another brand? Yes, the 510 fitting is standard. The point to check is the power available, since these reservoirs work at low coil values. ### Do old Zeus coils work on the Z models? That depends on the family, not on the model name. Z coils cover several generations, while the B and M families stay confined to their respective reservoirs. ### Why does a burnt taste sometimes appear so quickly? Common causes are a reservoir run too low on liquid, power applied beyond the range printed on the coil, or priming cut short after a change. ### Should the reservoir be rinsed between two liquids? A rinse in clean water and a full dry prevent flavours mixing. The coil itself is not rinsed and is replaced when the flavour profile changes markedly. ## Reading the range before choosing a Zeus vape tank A rebuildable origin, two capacity branches, four coil families and a name change along the way: the GeekVape catalogue fits inside those four markers. Choose by the coil the reservoir accepts first, by its format second, and never by the generation printed on the box alone. This platform logic shared between tanks and kits is not unique to GeekVape. You find it, in a different form, in the way [Vaporesso circulates its GTi coils](/uk/vaporesso-itank-t/) between its flagship reservoir and its kits, and the [Aspire range read through its coils](/uk/aspire-vape-tank/) makes the same point from the mouth to lung side. Since the liquid matters as much as the hardware at these values, our [guide to e-liquid](/uk/e-liquid-guide/) covers the ratios that suit them. Put together, those three checks, coil family, printed range and liquid, are what make a **Zeus vape tank** predictable rather than temperamental.
