The compact power, bright OLED display, long lasting battery capacity and easy to use menu system makes the Innokin CoolFire IV the ultimate compact vaporiser.
The CoolFire IV uses Vrms DC current and is very accurate with a power deviation of 0.1W. The full 40 watts is precisely maintained between resistances of 0.3 - 2.5 ohms. There is no wasted power and exact accuracy means you are always vaping the power level that you choose. Vrms provides superior precision in delivering the exact wattage required and stable power means better vapour.
