The new version of the Innokin Prism Coil is designed to fit the Endura T22E and Endura T18E vape tanks. Another model is available to fit the T22 and T18 Tanks. Registering at 1.5 Ohm resistance, the T18E Coil is intended for low-wattage mouth-to-lung vaping, making it ideal for all vapers. Like most other Innokin Coils, the Prism T18E Coil leverages the ‘no spill coil swap’ system. You are recommended to use this kit with e-liquid up to 60%VG. The t18e coils are only compatible with the "E" version T18E or T22E 2ml tank or "E" version kits.
