Geekvape B-Series Replacement Coils (Pack of 5)

The Geekvape B-Series Replacement Coils are a versatile and widely used coil platform, designed to deliver dependable flavour output, stable vapour production, and broad compatibility across a large range of Geekvape pod kits and tanks. Formerly known as Aegis Boost coils, the B-Series continues the same proven design under updated naming and packaging, remaining fully compatible with the same devices.

Engineered to support both mouth-to-lung (MTL) and direct-to-lung (DTL) vaping styles, B-Series coils give users the flexibility to tailor power level, airflow and e-liquid choice without changing hardware. Whether you prefer a tighter draw with discreet vapour or a warmer, more open inhale, the B-Series offers a coil option to match.

Each pack contains five genuine Geekvape replacement coils.

B-Series Coil Platform Overview

Designed for Flexibility and Everyday Performance

The Geekvape B-Series was developed as a multi-purpose coil system for compact pod kits and tanks. Using a push-fit installation design, coils can be replaced quickly without threading, reducing downtime and simplifying maintenance.

By combining mesh heating elements with optimised airflow and wicking, the B-Series delivers consistent output across a wide wattage range, making it suitable for both newer vapers and experienced users.

Mesh Coil Construction and Materials

Even Heating and Reliable Wicking

All Geekvape B-Series coils are constructed using KA1 Kanthal mesh, chosen for its durability, heat stability and predictable resistance behaviour. The mesh structure increases the surface area in contact with the cotton wick, allowing e-liquid to heat evenly and efficiently.

This design provides:

• Faster heat ramp-up

• Consistent vapour density

• Clean, repeatable flavour

• Reduced dry hits when used within recommended wattages

The organic cotton wicking system is engineered to handle both thinner high-PG liquids and thicker high-VG blends, depending on the selected coil resistance.
