The Innokin T18e battery really needs no introduction; the familiar power-source for one of the most successful mouth-to-lung vape kits available on the market today, the T18e is a simple, neat and user-friendly battery.
Eschewing gimmicks such as variable wattage and temperature control, the T18e features a single button, used for both switching it on/off and firing the tank sat above. Coloured LEDs give an accurate indication as to the battery's charge, and you don't have to worry about it giving out when you most need it; the T18e has a 1000mAh capacity, more than enough to see a mouth-to-lung tank through the day. The unit also puts out a consistent 14w of power, which is a perfect punch to give you a satisfying lungful of vapour without running the battery down too quickly.
Any number of tanks can sit neatly atop the T18e, such as the Innokin T20-S, thanks to it's widely utilised 510 connection, and the unit is available in a selection of bright, eye-catching colours, so even with such a simple battery you can still give it your own degree of character.
