The Geekvape B Series Replacement Coils are the genuine, official replacement coils for one of the most versatile and widely used coil platforms in the UK vaping market — covering the Aegis Boost, Aegis Boost Plus, Aegis Boost 3, Aegis Hero, Aegis Hero 2, Aegis Hero 5, H45, Z50, M100, Mero, Obelisk 65 FC, Zeus Nano, and Zeus Nano 2 devices in a single, unified coil family.

Originally launched as the Aegis Boost replacement coils, the B Series name now covers the full range across all compatible Geekvape platforms, and the packaging has been updated to reflect this. However, the coils themselves remain unchanged in construction, performance, and compatibility. Every pack contains five coils, and the full B Series range spans resistances from 0.2Ω right up to 1.2Ω — covering everything from tight MTL nic salt vaping at low wattage right through to warm RDL and full DTL cloud chasing at higher wattages, all from the same push-fit coil platform that takes seconds to install without any tools.

Whether you're running an Aegis Boost on 20mg nic salts with a 1.2Ω coil or pushing an Aegis Hero 5 at 50W with a 0.2Ω mesh for maximum cloud production — the B Series has exactly the right coil for your setup, and at QSS Vape you'll always find 100% genuine Geekvape stock.


KA1 Mesh Construction — Better Flavour, Longer Life

Every coil in the Geekvape B Series uses KA1 mesh construction throughout—and mesh is key to why these coils consistently outperform older round-wire coil designs in both flavour accuracy and coil longevity. The mesh surface heats e-liquid evenly across a far wider area than a conventional wound coil of the same resistance, eliminating the hot spots that cause uneven flavour and premature cotton degradation. The result is a cleaner, more consistent flavour profile from the very first puff right through to the end of each coil's life — with noticeably less of the gradual flavour drop-off that vapers using round-wire coils often experience over time.

The Boost versions of the B Series coils — covering the 0.2Ω through 0.6Ω options — are the newer generation of the range, featuring advanced materials and improved heat-load engineering that extend coil lifespan by up to 100% compared to the older B coil generation. Each Boost coil is rated for approximately 50–60ml of e-liquid before needing replacement — an exceptional lifespan for a push-fit Pod coil that makes the B Series one of the most cost-effective coil ranges in the UK right now.


Push-Fit Installation — No Tools, No Threading, No Mess

Every Geekvape B Series coil uses Geekvape's simple push-fit installation system — arguably the most convenient coil-change system available from any brand in the UK vape market. There's no threading, no screwing, and no risk of cross-threading. Pull the old coil out of the Pod or tank, prime the fresh coil, push it into the coil seat until it clicks firmly into place, and vape. The whole process takes less than thirty seconds from start to finish and requires no tools. It's a brilliantly practical system that makes the Geekvape B Series platform one of the easiest coil-based setups to use every day.


The Full B Series Coil Range — Choosing the Right Resistance

The Geekvape B Series covers a wide wattage range from 8W to 58W across five resistance options, each delivering a distinct vaping experience:

0.2Ω B Series Mesh Coil (Boost) — 50W–58W
The most powerful coil in the B Series range and a full DTL option for vapers who want maximum cloud production and bold, intense flavour. The 0.2Ω operates at 50–58W and requires a high-VG e-liquid of 60% VG or above for consistent wicking and performance. Not suitable for nicotine salts at high strength — the vapour production at this wattage makes anything above 6mg uncomfortably harsh. A brilliant choice for experienced sub-ohm vapers running the Aegis Hero 5 or M100 and wanting the absolute ceiling of B Series performance.

0.3Ω B Series Mesh Coil (Boost) — 30W–38W
A warm, open restricted DTL coil that sits just below the 0.2Ω in intensity — producing dense, satisfying clouds and rich flavour at a slightly more moderate wattage that suits a wider range of devices comfortably. Best with high-VG e-liquids of 60% VG or above at 3mg–6mg strength. A solid all-round choice for vapers who want strong DTL performance without pushing to 50W+.

0.4Ω B Series Mesh Coil (Boost) — 25W–33W
The versatile mid-point of the B Series range — a balanced RDL coil that delivers a warmer, more vapour-forward draw than the higher-resistance MTL options without committing to the full open DTL experience of the 0.2Ω or 0.3Ω. The 0.4Ω produces excellent flavour and satisfying vapour at a comfortable wattage that most Geekvape devices handle easily. Works well with 50/50 freebase e-liquids at lower nicotine strengths and high-VG e-liquids alike — a genuinely versatile coil that works brilliantly as an all-day setup for vapers who want more than MTL without going full DTL.

0.6Ω B Series Mesh Coil (Boost) — 15W–25W
The lightest touch of the DTL/RDL B Series options — a warm, slightly restricted draw that sits right on the boundary between a loose MTL and a light RDL. The 0.6Ω is one of the most popular options in the entire B Series range because it hits a sweet spot that works across a very wide range of vapers — warm enough to deliver real flavour and satisfying vapour, but cool and accessible enough that it doesn't require high-VG e-liquids or high wattages to perform at its best. Pairs well with both 50/50 freebase e-liquids at 3mg–6mg and higher-VG shortfills, making it a genuinely flexible everyday coil for the Aegis Boost and Hero platforms. For best results, use 50/50 PG or higher e-liquids.

1.2Ω B Series MTL Coil — 8W–12W (also compatible: 0.8Ω at 12W–16W)
The MTL specialist of the B Series range — a tight, cool, cigarette-style mouth-to-lung coil that operates at just 8–12W and delivers everything a vaper switching from cigarettes or running high-strength nic salts could need. The draw is noticeably more restricted than any of the RDL/DTL options above — cool, smooth, and satisfying with a throat hit that feels completely natural and familiar — and the low wattage means it works perfectly with nicotine salts at 10mg or 20mg strength and 50/50 freebase e-liquids. If you're running an Aegis Boost or Zeus Nano primarily for nic salt vaping, the 1.2Ω is the coil to reach for. Best with 20mg and 10mg nicotine salt e-liquids and 50/50 freebase e-liquids.

How to Install and Prime Your B Series Coil

Installing a fresh Geekvape B Series coil is one of the most straightforward coil-change processes available — no tools, no threading, just push-fit simplicity. Remove the Pod or tank from your device and locate the coil seat. Pull the old coil out by gripping it firmly and pulling upward — it releases cleanly without twisting. Before fitting the fresh coil, prime it by applying three to five drops of e-liquid directly onto the exposed cotton wicking ports at the top and sides of the coil, then allow it to soak for three to five minutes. Push the primed coil firmly into the coil seat until it clicks securely into place. Reattach the Pod or tank to your device, fill with e-liquid, and start vaping at the lower end of the recommended wattage range — working upwards gradually over your first few puffs to bed the coil in gently. Never skip the priming step — it's the single most important thing you can do to maximise coil life and flavour quality.


When to Change Your B Series Coil

The Boost versions of the B Series (0.2Ω through 0.6Ω) are rated for approximately 50–60ml of e-liquid per coil — delivering roughly one to two weeks of regular daily vaping depending on frequency and chosen wattage. The MTL options (0.8Ω and 1.2Ω) typically last one to two weeks of moderate daily use. Sweeter e-liquids and higher wattages will shorten coil life, while cleaner profiles and moderate wattages extend it. The clearest sign a coil needs replacing is a change in flavour — a muted, flat, or slightly burnt taste means the cotton is spent. Reduced vapour production or a gurgling sound are secondary indicators. When any of these appear, swap in a fresh coil from your pack of five.


E-Liquid Compatibility

Coil Best E-Liquid
0.2Ω High-VG 60VG+ shortfills — 3mg–6mg freebase
0.3Ω High-VG 60VG+ shortfills — 3mg–6mg freebase
0.4Ω 50/50 freebase or high-VG — 3mg–6mg
0.6Ω 50/50 PG or higher — 3mg–10mg freebase
1.2Ω 50/50 VG/PG and nicotine salts — 10mg & 20mg

All 10ml nicotine salt e-liquids at QSS Vape — including the Elux Salt, Crystal Salt, Just Juice Bar, Pixl, and Riot X nic salt ranges — are perfectly suited to the 1.2Ω B Series MTL coil. The full range of 100ml 70VG/30PG shortfills at QSS Vape pairs brilliantly with the 0.2Ω and 0.3Ω Boost coils for maximum DTL performance.
