It will only work on a battery capable of firing a coil of 0.5ohm or lower. You must be sure that your mod AND batteries can handle SUB OHM coils. If you're using a regulated mod, make sure it can handle the amps. For mechanical mod users, please use 20 Amp batteries or higher. Use the OHMS LAW CALCULATOR, CHECK YOUR AMPS, and be safe!Tip for new users: We strongly suggest 6mg eLiquid or lower with this atomizer. Sub-ohm atomizers produce higher throat hit than low and standard resistance coils. Using this tank with a nicotine level above 6mg will usually taste burnt or harsh.Note - Vape Crew only stock genuine SMOK products!
