What Geekvape kits use B Series coils?

The Aegis Boost (all versions including Boost 2, 3, and Plus), Aegis Hero (including Hero Q and Hero 5), and the H45 kit. B Series coils also fit Z Nano tanks and the Force Cartridge. One coil type covers the lot.

What's the difference between Geekvape B Series coil resistances?

The 0.15-0.3Ω coils are DTL for big clouds at 30-75W with high VG liquids. The 0.4-0.6Ω coils sit in the RDL range at 15-35W. The 0.8Ω and 1.2Ω are MTL coils for nic salts at 8-16W. Lower resistance means more power, more vapour, and more e-liquid used.

Do Geekvape B Series coils fit the H45?

Yes. The H45 uses B Series coils the same way the Aegis Boost and Hero kits do. All seven resistances work with it. Push-fit installation is the same across all compatible kits.

What wattage should I use for Geekvape B Series coils?

It depends on the resistance. The 1.2Ω runs at 8-12W, the 0.6Ω at 15-25W, and the 0.15Ω goes up to 75W. Each coil has a recommended range printed on the side. Stay within that range for the best coil life.

Are Geekvape B Series Boost coils different from standard B coils?

The Boost versions (0.15Ω through 0.6Ω) last roughly twice as long as the older B coils, around 50-60ml of e-liquid per coil. The 0.8Ω and 1.2Ω MTL coils don't have Boost versions and use standard construction.

Geekvape B Series Replacement Coils

Geekvape B Series Coils

The Geekvape B Series coils are the replacement coils for the Aegis Boost range, Aegis Hero kits, the H45, and all Z Nano tanks. Seven resistances from 0.15Ω up to 1.2Ω cover everything from tight MTL through to full DTL. All of them use KA1 mesh and push straight in with no threading.

Five of the seven (0.15Ω to 0.6Ω) are the newer Boost versions that last roughly twice as long as the older B coils. The two MTL options (0.8Ω and 1.2Ω) use standard construction. Each pack has five coils. Nic salts, 50/50 freebase, and high VG shortfills all work depending on which resistance you pick.

B Series Coil Resistances

DTL Coils

Coil	Wattage	E-Liquid	Notes
0.15Ω Boost	60–75W	Max VG, high VG shortfills	Most vapour, highest wattage
0.2Ω Boost	50–58W	High VG, shortfills	Large clouds, slightly less power
0.3Ω Boost	30–38W	High VG 70/30, shortfills	Mid-range DTL

These three are for open lung vaping with high VG or max VG e-liquids. The 0.15Ω pulls the most power and puts out the most vapour. The 0.3Ω sits at a lower wattage and works well if you want DTL without burning through battery and liquid as fast.

RDL Coils

Coil	Wattage	E-Liquid	Notes
0.4Ω Boost	25–35W	50/50, high VG	Restricted DTL draw
0.6Ω Boost	15–25W	Nic salts, 50/50, high VG	Loose MTL or tight RDL

The 0.4Ω and 0.6Ω sit between MTL and DTL. The 0.6Ω is the most flexible coil in the B Series range because it handles nic salts, 50/50, and high VG without issues. Good starting point if you're not sure which resistance to go for.

MTL Coils

Coil	Wattage	E-Liquid	Notes
0.8Ω	12–16W	Nic salts, 50/50	Tight MTL draw
1.2Ω	8–12W	Nic salts, 50/50	Tightest draw, lowest wattage

Both MTL coils work best with nic salts at 10mg or 20mg. The 1.2Ω is the tightest pull in the range and uses the least battery. These two use standard construction rather than the Boost version, so coil life is shorter than the lower resistances.

Aegis Boost Coil Compatibility

The B Series coils work across a long list of Geekvape kits and tanks. If your kit is on this list, B Series coils are what you need.

Aegis Boost Kits

Aegis Boost
Aegis Boost 2 (B60)
Aegis Boost 3
Aegis Boost Plus
Aegis Boost Luxury Edition

Aegis Hero Kits

Aegis Hero
Aegis Hero Q
Aegis Hero 5

Other Compatible Hardware

H45 Kit
Z Nano Tank
Z Nano 2 Tank
Z Nano 3 Tank
Z Nano MTL Tank
Aegis Hero Cartridge
Boost Cartridge
Force Cartridge

The H45 kit uses B Series coils even though it's not part of the Aegis Boost or Hero range. Same goes for all four Z Nano tank versions. If you're searching for "H45 coils" or "Z Nano coils," B Series is the one you want.

Push-Fit Installation

B Series coils push straight into the pod base. Pull the base off, press the coil in until it clicks, and put the base back on. No threading or twisting needed.

Prime every new coil before you vape on it. Drop e-liquid onto the exposed cotton through the top and side ports, then leave it for three to five minutes. This stops the cotton burning on the first few draws.
