The atomizer is the engine or heating element of the electronic cigarette. Vapor is created when e-liquid comes into contact with the atomizer, which is heated by the battery. Atomizers have a significantly shorter life-span than batteries. The life of an atomizer is dependent on variables such as: frequency of use, type of e-liquid used, applied voltage, etc. It's a good idea to have extra atomizers on hand.
