Geekvape Z XM Boost Replacement Coils

The Geekvape Z XM Boost Replacement Coils are the latest generation of replacement coils for the Geekvape Z Series sub-ohm tank platform — the coil range previously known as the Zeus coils, now updated and significantly improved as the Z XM Boost. If you've been running original Z Series coils in your Geekvape tank and looking for the direct replacement, the Z XM Boost is exactly what you need — same push-fit installation, same resistance options, same compatible tanks, but with a meaningfully upgraded mesh and cotton construction that delivers approximately double the coil lifespan and noticeably improved flavour consistency over the original Z coil generation.

Sold in a pack of five and available in three resistance options — 0.15Ω (70–85W), 0.2Ω (70–80W), and 0.4Ω (50–60W)— the Z XM Boost coils cover the full DTL sub-ohm performance range from moderate high-wattage vaping right up to the most powerful, cloud-forward sub-ohm experience the Z Series platform can deliver. Every coil uses Kanthal A1 mesh throughout for fast, even heating and consistently excellent flavour from first puff to last — and the XM Boost generation is rated for about 50–60ml of e-liquid per coil before needing replacement.

XM Boost Technology — What Makes It Different

The XM Boost designation isn't just a name change — it represents a genuine generational improvement over the original Z Series coils in three key areas that matter most to serious DTL vapers.

Extended Coil Lifespan: The original Z Series coils were rated for approximately 25–30ml of e-liquid per coil under normal use. The Z XM Boost generation doubles that to approximately 50–60ml per coil — meaning roughly twice as many days of vaping from every pack of five, and a meaningfully lower ongoing cost per puff that adds up significantly over time.

Improved Flavour Consistency: The upgraded Kanthal A1 mesh construction and refined cotton wicking in the XM Boost coils maintain flavour quality more consistently throughout the coil's extended lifespan. With the original Z coils, many vapers noticed a gradual decline in flavour clarity and accuracy as the coil approached the end of its life. The XM Boost construction significantly reduces this effect — the flavour you get at 10ml into a fresh coil is much closer to the flavour you get at 50ml.

Mouthfeel Booster: The XM Boost coils incorporate Geekvape's Mouthfeel Booster technology — an engineering refinement in the coil's airflow and vapour path that enhances the tactile character of each draw, producing a smoother, more satisfying hit with denser vapour that feels genuinely excellent on every puff.

Three Resistance Options — Choosing the Right Z XM Boost Coil

0.15Ω Z XM Boost Mesh Coil — 70W–85W | Full DTL

The most powerful coil in the Z XM Boost range — an intense, full-on DTL mesh coil for vapers who want the maximum cloud production and the most immersive flavour experience the Z Series platform can deliver. At 70–85W, the 0.15Ω produces the warmest, densest vapour and the most open, unrestricted DTL draw of the three options — a genuinely impressive performance that rewards vapers running capable high-wattage mods like the Aegis Legend 2 or Aegis Legend 3. The 0.15Ω and 0.2Ω are close in wattage range and both suit full DTL vaping — the 0.15Ω runs slightly warmer and pulls slightly more power, making it the choice for vapers who want the absolute ceiling of Z XM Boost performance. Requires a device comfortably capable of sustaining 70W or above. Best with high-VG e-liquids of 70% VG or higher at 3mg freebase strength.

0.2Ω Z XM Boost Mesh Coil — 70W–80W | Full DTL

A companion to the 0.15Ω at a marginally higher resistance — delivering a very similar full DTL experience at essentially the same wattage range but with a slightly different ramp-up characteristic and heat distribution that some experienced vapers prefer for its subtly smoother draw character. The 0.2Ω is an excellent choice for vapers who already know they love the full DTL experience but want to try a slightly different coil build to compare flavour and vapour output at similar wattages. Like the 0.15Ω, it requires a device capable of sustaining 70W+ comfortably. Best with high-VG e-liquids of 70% VG or higher at 3mg freebase strength.

0.4Ω Z XM Boost Mesh Coil — 50W–60W | DTL

The most accessible and versatile coil in the Z XM Boost range — a slightly higher resistance that operates at a more moderate 50–60W while still delivering a full, satisfying DTL experience with excellent flavour and solid cloud production. The 0.4Ω is the natural starting point for vapers who are new to the Z Series platform or who are running a device that sits more comfortably in the 50–60W range. It's also a genuinely popular all-day coil choice for experienced vapers who want strong DTL performance with better battery economy than the 0.15Ω or 0.2Ω options. The slightly lower wattage means each coil runs at a marginally lower heat load, which can extend coil life beyond the already impressive 50–60ml XM Boost rating. Best with high-VG e-liquids of 70% VG or higher at 3mg freebase strength.

Kanthal A1 Mesh — Built for Performance and Longevity

Every Z XM Boost coil is built with Kanthal A1 mesh throughout—a material chosen for its outstanding thermal stability, resistance to thermal fatigue, and consistent heating performance across repeated use. Kanthal A1 is prized in coil manufacturing for its ability to reach operating temperature quickly, hold that temperature consistently throughout each draw, and maintain its structural integrity over a far longer lifespan than softer wire materials. The mesh format distributes heat evenly across the full surface of the wicking cotton—eliminating the localised hot spots that can cause uneven flavour and dry hits in conventional round-wire coils—delivering cleaner, more accurate, consistently satisfying flavour from every puff throughout the coil's extended lifespan.

The push-fit installation system means replacing a Z XM Boost coil takes seconds and requires no tools — pull the old coil straight out of the tank base, push the fresh primed coil in until it clicks firmly into place, and vape. The same straightforward system that has made the Geekvape Z Series platform so consistently popular with experienced sub-ohm vapers for years.

Geekvape Z XM Boost coils are compatible with the following Geekvape tanks and kits:

Z Series Tanks (formerly Zeus):

• Geekvape Zeus Sub-Ohm Tank
• Geekvape Zeus Sub-Ohm Tank SE (2022)

Please note: Z XM Boost coils use the same push-fit installation as the original Z Series coils and are a direct replacement for that platform—they are fully backwards compatible with all Z Series tanks that previously accepted the original Z coils. If you previously used Z Series coils in your Zeus or Z tank, the Z XM Boost coils are the upgraded direct replacement.

Z XM Boost coils are not compatible with Geekvape's B Series, P Series, Q Series, or any other Geekvape coil platform. Please check your device carefully before ordering.

How to Install and Prime Your Z XM Boost Coil

Replacing a Z XM Boost coil is a quick, clean push-fit process that takes less than a minute. Ensure the tank has e-liquid before installing the coil— installing a coil into a dry tank can cause the cotton to dry out prematurely. Remove the old coil from the base of the tank by pulling it straight out firmly. Before fitting the fresh coil, prime it by dripping three to five drops of e-liquid directly onto the exposed Kanthal mesh and wicking cotton through the coil's wicking holes; then let it soak for three to five minutes. Push the primed coil firmly into the coil seat until it clicks securely into place — no threading, no twisting, just a clean push-fit. Fill the tank with e-liquid, then start vaping at the lower end of the recommended wattage range and work upwards gradually over the first few draws. Never vape immediately on an unprimed coil — dry hits on a fresh Z XM Boost coil are the most common cause of premature coil failure and can permanently damage the cotton before it ever gets a chance to perform properly.

When to Change Your Z, XM Boost Coil

The Z XM Boost generation is rated for about 50–60ml of e-liquid per coil—roughly one to two weeks of regular daily sub-ohm vaping, depending on frequency, chosen wattage, and e-liquid type. Sweeter e-liquids and the higher wattage options (0.15Ω/0.2Ω) will naturally shorten coil life, while cleaner profiles and the more moderate 0.4Ω wattage will extend it further. The clearest sign a Z XM Boost coil needs replacing is a noticeable change in flavour—a flat, muted, or slightly scorched taste indicates the Kanthal mesh or cotton is nearing the end of its life. Reduced vapour production and a darker discolouration of the e-liquid in the tank are secondary indicators. With five coils in every pack, you'll always have a fresh one ready to go.

E-Liquid Compatibility

All three Z XM Boost coil options are designed exclusively for high-power DTL sub-ohm vaping and perform best with high-VG e-liquids of 70% VG or higher. This makes the Z XM Boost coil range a natural and outstanding partner for the full selection of 100ml 70VG/30PG shortfills available at QSS Vape — including the Lancashire Creamery, Future Juice, Wild Roots, Mix Labs, and Just Juice shortfill ranges — all of which pair brilliantly with the Z XM Boost coil platform at the wattages these coils operate at.

Nicotine salts and 50/50 e-liquids are not recommended for use with Z XM Boost coils. The high-power DTL wattage ranges make high-strength nicotine salts uncomfortably harsh and can also cause thinner 50/50 formulas to flood the coil at these operating temperatures. Freebase e-liquids at 3mg or below are the correct pairing for the Z XM Boost platform.
