Geekvape B Series Coil

Five resistances across two coil versions, all sharing the same press-fit base. The Geekvape B Series coils use KA1 mesh elements and cover everything from tight 1.2ohm MTL draws at 10W through to open 0.2ohm DTL clouds at 58W.

That range matters because the B Series is Geekvape's universal coil platform. It runs across the Aegis Boost family, the Zeus Nano tanks, and a handful of other Geekvape kits. Sold in packs of five. Pick your resistance, drop it in, and you are set.

Why vapers choose the B Series Coils:

• One coil platform for multiple kits means you do not need different coils when you own more than one Geekvape device, which saves money and drawer space

• KA1 mesh across every resistance gives faster heat-up and more even flavour than traditional round-wire coils, even at the low-wattage MTL end

• Five resistances from 0.2 to 1.2ohm cover every draw style from tight MTL right through to wide-open DTL clouds without leaving the B Series ecosystem

• Upgrade Boost version doubles the rated coil life from 20ml to 40ml of liquid, which is a noticeable improvement if you vape daily

• Press-fit installation takes seconds. No screwing, no alignment issues, just push and go

Geekvape B Series Coil Features

One Coil Family, Five Different Vapes

Most brands make you learn a whole new coil system every time you pick up a different device. Geekvape built the B Series to work across the Aegis Boost lineup, the Hero pods, the Zeus Nano tanks, and the Force cartridge. Own two or three Geekvape Kits? Same coils for all of them.

KA1 Mesh Does the Heavy Lifting

Every B Series coil uses kanthal mesh rather than wound wire. The flat mesh surface means more contact with your e-liquid at once, so heating is faster and more uniform. Result: cleaner flavour, denser vapour, and fewer of those dead spots that make traditional coils taste uneven after a few days.

The Upgrade Boost Line Is Worth Knowing About

Geekvape released the Upgrade Boost version alongside the original Classic. The difference? Redesigned wicking and heating structure that nearly doubles coil life. They claim 40ml of liquid per coil versus 20ml for the Classic. In real-world terms, that is roughly twice as many days before you notice flavour drop-off. Not bad for the same price.

MTL and DTL From the Same Box

The 0.6ohm and 1.2ohm handle mouth-to-lung vaping with a tighter draw, working nicely with Nic Salts at 10-20mg. The 0.2, 0.3, and 0.4ohm coils open things up for direct-lung hits with freebase liquid. You can genuinely switch between vaping styles just by swapping the coil. Most coil ranges make you pick a lane.

Built to Handle the Aegis Beating

The Aegis line is known for being tough. IP68-rated, shock-resistant, built for vapers who actually take their devices outside. The B Series coils match that philosophy: KA1 mesh holds up well under daily use, and the press-fit connection stays snug even in devices that get knocked around.

Geekvape B Series Coil Resistance Options

Five options, and they cover very different territory. Here is where each one sits.

Best pick for flavour chasers: the B0.4ohm at 25-35W. Sits in that sweet spot between MTL restriction and DTL openness. Restricted direct-lung draws pull strong flavour without burning through your liquid the way the lower-resistance options can. Pairs well with freebase up to about 9mg.

Best for big clouds: the B0.2ohm at 50-58W. Highest wattage in the range, widest airflow, warmest draw. Use freebase liquid at 3mg or lower. This is the coil for people who came from sub-ohm tanks and want that experience in a pod format.

Good middle ground: the B0.3ohm at 30-38W. Still DTL, still cloudy, but a bit more restrained than the 0.2. Nice balance if 58W feels like too much power draw from a pod kit battery.

• B0.6ohm (15-25W): RDL and MTL territory, handles nic salts up to 30mg nicely

• B1.2ohm (10-14W): Pure MTL, tight draw, best with 50/50 nic salts at 10-20mg

How to Set Up the Geekvape B Series Coil

Quick process. Under two minutes, including the priming wait.

1. Remove the pod or tank from your Geekvape device. Empty any remaining liquid.

2. Pull the old coil out of the pod base or tank base. Press-fit, so it should come out with a firm pull.

3. Take a fresh B Series coil from the pack. Put three to four drops of e-liquid directly onto the cotton ports on the sides and the top of the coil.

4. Press the new coil firmly into the base until it seats fully. You will feel it lock in.

5. Reattach the pod or tank, fill with e-liquid, and let it sit with the ports facing up for around four minutes. Give the wick time to pull liquid all the way through before you take that first draw.

6. Start at the low end of the recommended wattage and work up over a few puffs. No need to rush this step.

What's in the Geekvape B Series Coil Box

Five coils in your selected resistance, sealed in an outer box. No e-liquid, no pod, no device included. Just the coils.

The Universal Coil for Geekvape's Aegis and Zeus Range

The B Series is Geekvape's cross-device coil platform. That means one coil type covers a lot of ground.

The Aegis Boost family takes them: that includes the original Boost, the Boost Plus, and the Boost 2 (B60). The Aegis Hero line works too, covering the original Hero, the H45, the H45 RTE, H45 Classic, and the newer Hero 5.

Beyond the pod kits, the B Series fits the Zeus Nano MTL Tank and the Zeus Nano 2 tank for vapers who use tank-and-mod setups. The Aegis Force pod cartridge and the Z50 Kit are also compatible, along with the Obelisk 65 and M100.

That is a lot of devices from one coil. If your Geekvape device is not listed here, check your device manual before ordering. Not every Geekvape product takes the B Series.

About Geekvape

Geekvape built its reputation on the original Aegis mod. IP68 dust and water resistance in a vape device was a genuine first when it launched, and that ruggedness became the brand's identity. The B Series coil platform came out of the Aegis Boost line and then expanded outward across the Hero, Zeus Nano, and Force families.

It is now one of the most widely compatible coil systems in the Geekvape ecosystem. Where other brands fragment their coil platforms across every new product, Geekvape kept the B Series as a constant. That decision means vapers who own multiple Geekvape devices only need to stock one coil type.

Stock Up and Save

Five coils sounds like plenty until you are three weeks in and down to your last one. With daily use, each coil lasts roughly one to two weeks depending on your liquid and wattage. Grab a couple of packs and rotate through them.

Every order from Pirate Vapes is packed carefully and dispatched the same day if you order before 4 pm. TPD-compliant stock only, age-verified checkout, over-18s only. Free Pirate Post applies on orders over £25, so adding a second pack to the basket gets you there.

Conclusion

The Geekvape B Series coils work across more devices than almost any other coil system in the UK market right now. Five resistances cover MTL through DTL, the KA1 mesh delivers consistent flavour, and the Upgrade Boost version nearly doubles coil life over the Classic.

If you own anything in the Aegis Boost, Hero, or Zeus Nano range, the B Series is almost certainly your coil. Browse more Geekvape Coils and vape accessories at Pirate Vapes.

FAQs

What devices are compatible with the B Series Coil?

The Aegis Boost family (original, Plus, B60), the Aegis Hero range (H45, H45 RTE, H45 Classic, Hero 5), the Zeus Nano and Nano 2 tanks, the Z50 Kit, and the Aegis Force pod cartridge. That covers most of Geekvape's pod and MTL lineup.

How long does each B Series coil last?

One to two weeks with regular daily use. The Upgrade Boost version is rated for 40ml of liquid compared to 20ml for the Classic, so roughly double the lifespan if you pick the newer version.

Which B Series resistance is best for nic salts?

The B0.6ohm and B1.2ohm are your options. The 1.2ohm gives the tightest draw and works well with 50/50 nic salts at 10-20mg. The 0.6ohm is slightly looser and can handle nic salts up to about 30mg.

What is the difference between Classic and Boost versions?

Classic coils are the original design, compatible with older Aegis Boost devices. The Upgrade Boost version has redesigned wicking and heating for longer coil life and is designed for newer devices like the B60 and Hero 5. Both share the same press-fit base.

Can I use high VG liquid with the B Series?

For the lower-resistance DTL coils (0.2, 0.3, 0.4ohm), yes. They handle 70/30 and higher VG ratios well. The MTL coils (0.6 and 1.2ohm) work best with 50/50 blends. Thick liquid in a high-resistance MTL coil will wick slowly and may cause dry hits.

Do I need to prime the B Series coils before use?

Yes. Always. Drop liquid onto the cotton ports before fitting the coil, fill the pod or tank, and wait a few minutes before vaping. Skipping this step will burn the cotton on the first draw.
