This device is primarily a battery operated product designed to turn nicotine and other chemicals (including solvents and flavoring agents) into a vapor; an atomizer heats the e-liquid producing the vapor inhaled by the user. A rechargeable battery (w/wo LED indicator) of different sizes and output powers to the atomizer. Note that the battery output and the resistance of the heating coils in the atomizer determine the vaping capacity of the e-cigarette.
