Geekvape coils, the official compatibility table

Two packs of Geekvape coils can both say 0.2 ohm on the box, and only one of them will seat in your tank. The brand files its coils into lettered series, splits several of them into Boost, XM or MTL versions, and also sells cartridges with the coil already built in. Shop listings often blur these catalogues together. Before you order, the real question is which family your kit belongs to, according to Geekvape rather than the retailer.

Geekvape coils by device, the official matches

The series follows from the exact name of the tank, cartridge or kit, never from the resistance value. Z Sub-ohm and Z Fli tanks take Z series coils, the Z Nano, Z Nano 2 and Z Nano 3 tanks and the Boost, Hero and Force cartridges take B series coils, and the Z Max takes the M series and nothing else.

The table below uses only what Geekvape publishes on its product pages, its official store and its coil overview page. Every power range is the one the maker states for that exact coil.

Device (Geekvape name)	Series	Published values and ranges
Z Sub-ohm, Z Subohm 2021, Z Sub-ohm SE, Z Subohm Tank 5, Z Fli, Z Fli 2	Z	Z0.15 XM 70-85 W, Z0.2 XM 70-80 W, Z0.4 XM 50-60 W, Z0.25 Dual 45-57 W
Z Nano, Z Nano 2, Z Nano 3	B	B0.2 50-58 W, B0.3 30-38 W, B0.4 25-35 W, B0.6 15-25 W
Aegis Boost, Boost Plus, B60 (Boost 2), Boost 3, Aegis Hero, H45 (Hero 2), Hero 5 and Aegis Force cartridges	B	same values, plus B0.15 60-75 W for the Force cartridge
Z Nano MTL	B MTL	B0.8 MTL 12-16 W, B1.2 MTL 8-12 W
Z Max	M	M0.14 60-80 W, M0.3 Dual 55-65 W, M0.2 Triple 70-85 W, M0.15 Quadra 85-100 W
Aegis Boost Pro, B100 (Boost Pro 2), Obelisk 60, E100	P	P0.15 XM 70-85 W, P0.2 60-70 W, P0.4 50-60 W, P0.5 40-50 W
Aegis Pod, AP2, Wenax Stylus, Wenax S-C, Wenax C1, G18 kit	G	from G0.6 (13-18 W) to G1.8 (7-9 W) depending on the device
Digi Pro and Digi Max with the JR cartridge	J	J 0.4 23-28 W, 0.6 18-25 W, 0.8 12-18 W, 1.2 8-12 W

A matching series does not make every value usable. The device has to reach the bottom of a coil’s power range, otherwise the coil never heats properly. The Hero 5 tops out at 50 W and its page lists 0.2 to 1.2 ohm as supported, which leaves out the B0.15 rated at 60 to 75 W.

How to read the code printed on Geekvape coils

The code on a used coil holds almost everything you need to buy the right replacement. Read it in three parts, in this order, because each part answers a different question.

The letter names the device family

B, Z, M, P, G and J each name a coil format tied to a list of devices. No letter describes power or quality. The B series, for instance, runs from 0.15 to 1.2 ohm and covers both direct lung and mouth to lung vaping.

The number is the resistance

With Geekvape, the figure next to the letter is the value itself. Z0.2 reads as Z series, 0.2 ohm, and P0.4 reads as P series, 0.4 ohm. Not every brand works this way, and some code their coils without printing the value in the name, as our guide to reading Voopoo coil codes shows.

The suffix gives the version

XM and Boost mark revisions. Geekvape states that B Boost and Z XM Boost coils keep the interface of the earlier generation and fit any device that takes that series. MTL marks the B coils meant for a tighter draw. Dual, Triple and Quadra, found only in the M series, describe a build with several heating elements.

Two cases catch people out. The S and M after G1.2 separate two coils of the same value, the G1.2 S intended for the G18 kit and the G1.2 M for the Wenax S-C. The first Z Sub-ohm tanks also shipped with coils called Mesh Z1 (0.4 ohm) and Mesh Z2 (0.2 ohm), names the official store still shows on that tank’s listing.

Checking a match on Geekvape’s own pages

A retailer can put a line in the wrong row of a table. Geekvape publishes three kinds of page that cross-check each other, and two sources that agree beat any single shop listing:

the device page, whose box contents name the pre-installed coil and the spare;
the series page, which lists devices under “Compatible with” or “Designed for”;
the general coil page, which groups each series with its compatible products.

These pages sometimes disagree. On Geekvape’s store, the Z Fli 2 box contents give the Z0.4 XM a range of 45 to 57 W, while the Z series page rates it at 50 to 60 W. The 45 to 57 W range actually belongs to the Z0.25 Dual. When that happens we go with the series page and the range printed on the coil.

Six mix-ups between Geekvape series

Ordering mistakes rarely come from choosing the wrong value. They come from parts that look alike in a photo, or from one product sold in two versions that are hard to tell apart at a glance.

J cartridge or JR cartridge on the Digi

The J cartridge for the Digi Pro and Digi Max has its coil built in and is replaced whole. The JR cartridge is empty and takes J series coils. A pack of J coils bought for a J cartridge has nowhere to go.

Removable or fixed Hero cartridge

The H45 and Hero 5 cartridge comes in a removable coil version, which takes B and B MTL coils, and a fixed coil version at 0.4 or 0.6 ohm. Only the first one accepts a replacement coil.

The B0.15 and the Aegis Force

Among B Boost coils, the 0.15 ohm is listed by Geekvape for the Aegis Force cartridge only. The 0.2 to 0.6 ohm values are also listed for the Z Nano 2, Hero 2 and 5, Boost 2 and Boost 3.

The Z Max and the M series

The Z Max is the only tank Geekvape pairs with the M series, and its store listing says it takes nothing else. A 0.15 ohm Z coil does not belong in it, even though the value exists in both series.

Classic, Boost and XM

A revision fits where the old coil did, but its range sometimes moves. The original Z0.15 is rated at 80 to 90 W and the Z0.15 XM at 70 to 85 W. After switching versions, check the power setting again.

Four 0.2 ohm coils, four families

B0.2 (50 to 58 W), P0.2 (60 to 70 W), Z0.2 XM (70 to 80 W) and M0.2 Triple (70 to 85 W) share one value. They still belong to four series tied to four device families, and none of them replaces the other three.

UK TPD editions keep the same Geekvape coils

UK rules cap a refillable tank or cartridge for nicotine e-liquid at 2 ml, and nicotine e-liquid itself at 20 mg/ml in bottles of 10 ml at most. Geekvape therefore sells TPD editions: the Z Fli at 2 ml instead of 5.5 ml, the Z Nano 3 at 2 ml instead of 5 ml, the Z Nano MTL at 2 ml instead of 4 ml and the Force cartridge at 2 ml instead of 5 ml.

The coils do not change with the edition. The Z Fli page lists two Z series coils in both the standard box and the TPD box, and the official store sells several series as “UK Local” or “UK Local TPD” variants under the same coil names. Tank size plays no part in compatibility; the series does.

FAQ

Five questions that come up once the series is known, about devices the table does not cover in detail.

Which coils go in an Aegis Legend or Aegis Solo kit?

These mods come with a Z family tank. Geekvape’s store lists Z XM Boost coils for the Aegis Legend 2, 3 and 5, Aegis Max 2 and Aegis Solo 3 kits. The tank in the box decides, not the mod.

Do the Sonder Q, Wenax Q and Aegis Hero Q pods have a coil to change?

No. Their Q cartridges have a built-in mesh coil and are sold by resistance value. You replace the whole cartridge, as with the Wenax K1 and K2.

Which coils fit the Cerberus tank?

The Cerberus uses the new version Supermesh coils, X1 at 0.2 ohm (60 to 70 W) and X2 at 0.4 ohm (50 to 60 W). Geekvape also lists them for the Shield and Aero tanks.

Why do two 1.2 ohm B coils show different ranges?

Geekvape’s store sells a Classic B 1.2 ohm rated at 10 to 14 W and a B MTL 1.2 ohm rated at 8 to 12 W. They are two separate coils, and the power setting follows whichever one is fitted.

Will a Geekvape tank work on a mod from another brand?

The Z Nano 2, Z Max and Z Nano MTL use a 510 thread, the standard connection on mods. For the Z Nano MTL on any 510 mod, Geekvape asks you to set the power within the range of the coil fitted.

Ordering Geekvape coils from the device name

The whole compatibility table comes down to one idea. The exact name of the tank, cartridge or kit points to a series, the series offers its values, and the device’s maximum power rules out the ones it cannot drive. Every figure in this guide comes from Geekvape’s own pages, and where they contradict each other, the series page is our reference.

Write down the code printed on the coil you are using, letter and suffix included, before it goes in the bin. It is the simplest way to reorder the right Geekvape coils, and the same habit works for every brand that sells its coils in series.

More coils to know

Written for adult readers only. Vaping products usually contain nicotine, which is addictive, and they are not for sale to anyone under 18 in the UK. Nothing in this guide is a buying recommendation.
