# Geekvape Zeus coils for travel, packing the right series > Geekvape Zeus coils on a trip, how to tell which series fits your tank, pack the spares, change a coil away from home and set your mod safely. A coil burns out on the second evening of a trip, and the nearest vape shop is an hour's drive away. Once there, the assistant hands over a 0.15 ohm head that will not fit the tank. **Geekvape Zeus coils** carry exactly that trap, a single trade name shared by several tanks that do not all take the same part. Before zipping up the suitcase, it pays to know which one matches your kit, how to pack it and how to swap it without a workbench. ## Which Geekvape Zeus coils to pack, the short answer For a Zeus Sub-Ohm, a Z Fli or a P Sub-Ohm tank, the Geekvape Zeus coils to pack belong to the Z Series. Geekvape's page for that series currently lists three XM Boost values, 0.15, 0.2 and 0.4 ohm, and states that any device that takes a Z coil also takes its XM version. The Z Nano 3, which also turns up under the name Zeus Nano, is the exception. Geekvape lists it as compatible with the B Series, a different family of heads. The one check that matters before you leave is the exact name of the tank, not the word Zeus. ## Identifying your tank before you pack The Zeus name covers several tanks released over the years. Telling them apart before departure saves you from carrying a box of coils that will be no use once you arrive. ### Tanks that take the Z Series Two French retailers give the same compatibility list for Z coils, namely the Zeus Sub-Ohm, the Z Fli and the P Sub-Ohm. The second also names the Z Sub-Ohm SE. All of these heads are built for direct-to-lung vaping, with a mesh heating surface. The current tank in the range, the Z Subohm Tank 5, also points to the Z XM coils on its own product page. It fills from the top through a sliding cap, and its airflow is adjusted at the top as well. ### The Z Nano trap, also sold as Zeus Nano The Z Nano 3 page quotes a 5 ml capacity and compatibility with the B Series. In the UK, refillable tanks are limited to 2 ml, so that is the capacity a UK buyer should expect on the shelf. Coil values are where the mix-up starts. On its B Series page, Geekvape rates its 0.15 ohm B coil at 60 to 75 W, against 70 to 85 W for the Z0.15 XM. Same figure on the box, different head, and neither one replaces the other. That page also ties the Z Nano 2 to the B Series, while some retailer listings still describe Z coils as fitting a "Z Nano" without saying which generation. ## Geekvape Zeus coils and the mod you travel with The right value depends mostly on the mod that goes in your bag. A small single-battery mod cannot hold the same wattage as a dual-battery one, and the range the maker gives works as a safety rail. ### The three current XM Boost coils The Z0.15 XM runs between 70 and 85 W, the Z0.2 XM between 70 and 80 W, and the Z0.4 XM between 50 and 60 W. The 0.4 ohm is the only one of the three that stays below 70 W, which helps when your travel mod is the most compact one you own. On a mod that tops out at 60 W, only that 0.4 ohm coil falls within its stated range. The other two need at least 70 W, and the higher the wattage, the faster the batteries drain, which matters when you are a long way from a socket. ### Older coils still on sale Shops still clear earlier generations. The second of those retailers lists, for instance, an original Z 0.15 ohm rated at 80 to 90 W and a Z 0.25 ohm at 45 to 57 W, and specifies Kanthal A1 mesh. A box found at the back of a drawer may therefore need a different wattage from the new head bought the day before. The simplest habit is to note on your phone the exact name and wattage range of every coil you pack. Once on the road, without the packaging in front of you, that note stops you from running a head well beyond what it can take. ## Packing Zeus coils for the road New **Geekvape Zeus coils** travel best in their original packaging. It keeps the cotton away from dust and carries the printed product name, which settles any doubt between a Z and a B head when it is time to swap. A used coil raises a different issue. Soaked in liquid, it stains whatever it touches, so a small zip-lock pouch kept separately makes sense. A [vape case for travel](/uk/vape-case-travel/) then keeps heads, mod and bottles apart, so nothing ends up tangled with keys or coins. The tank itself travels better lightly filled and upright. Pressure changes in flight, or simply a bag being thrown around, push liquid out of a tank filled to the brim far more easily. ## Changing Geekvape Zeus coils away from home A coil swap works on a hotel table as well as it does on a kitchen worktop, as long as you follow the priming the maker describes. It is the step a traveller in a hurry is most tempted to rush. ### Priming the cotton Two methods are given for the Z Series. The first is to drip a few drops of e-liquid straight onto the cotton, through the coil's wicking holes, before fitting it. The second comes after filling, with the device switched off, by taking a few gentle puffs with the airflow closed down. Either way, the maker asks you to wait three to five minutes after filling so the cotton can soak through. It stresses one point, do not rush the priming, because dry cotton burns on the first puff and the head is then finished. ### Setting the mod after the swap Once the coil is pushed firmly into place, check that the mod reads the right resistance and that the wattage sits within the head's range. A mod left at 80 W for an old 0.15 ohm coil would overdrive a 0.4 ohm XM, which is rated to 60 W. Each Z XM coil is quoted to last around 50 to 60 ml of e-liquid, depending on use and liquid. A burnt taste or fading flavour signals it is time to replace it, as does a change of flavour or liquid that has sat in the tank for too long. ## Flying and going abroad with Zeus heads A new coil holds neither a battery nor any liquid. On a plane, the rules that matter concern the mod, its batteries and your bottles, all covered in our guide to [taking a vape on a plane](/uk/vape-on-a-plane/). Abroad, the question becomes one of supply. Shops outside the UK may not stock the exact head, and the rules on vaping vary widely, as our round-up of [countries where vaping is banned](/uk/countries-where-vaping-is-banned/) shows. At home, nicotine e-liquid is capped at 20 mg/ml and sold in bottles of 10 ml at most, which keeps each one small enough for a clear liquids bag. ## FAQ A few questions come up often when choosing and looking after a Zeus coil. ### What does sub-ohm mean for a Zeus coil? The term describes a coil whose resistance is below 1 ohm. Every head in the Z Series qualifies, from 0.15 to 0.4 ohm, and runs at high wattage for a direct-to-lung draw. ### Which e-liquid suits a Zeus tank? The maker recommends freebase nicotine e-liquid at 3 mg/ml or less, and advises against nicotine salts on Z Series heads. For a trip, choose the bottle before you leave, since liquid bought locally may not match that profile. ### How do you remove a Zeus coil without damaging the tank? With the mod switched off and the tank emptied over a tissue, take the head out in the order the tank's manual gives, as it varies between models. If a seal stays stuck to the old coil, recover it before throwing the coil away. ### Which coil fits other Geekvape kit? It depends on the tank or pod. The B Series page lists the Z Nano 2 and Z Nano 3, along with the Aegis Hero, Boost and Force cartridges, all tied to that series rather than to the Z Series. ### Do Z XM coils fit an older Zeus tank? Yes, according to the maker, which says any device that takes a Z coil also takes its XM Boost version. Only the wattage range changes, so read it on the packaging before the first setting. ## Geekvape Zeus coils, the right habit before you go The Zeus name is not enough to choose a head. The Zeus Sub-Ohm, Z Fli and P Sub-Ohm take the Z Series, while the Z Nano 3 needs the B Series, with different wattage ranges for the same figure on the box. Well identified, kept in their box and primed without haste on arrival, **Geekvape Zeus coils** travel as easily as the rest of your kit. The same care applies to everything that goes in the bag, from the mod to the bottles. ## Next legs of the trip - [Can you take a vape on a plane, from packing to landing](/uk/vape-on-a-plane/) - [Vape case for travel, what it should keep apart](/uk/vape-case-travel/) - [Countries where vaping is banned, and what each ban covers](/uk/countries-where-vaping-is-banned/) Éther Nomade writes for readers aged 18 and over.
