Electronic Cigarette is a battery-powered device which simulates tobacco smoking. It generally uses a heating element that vaporizes a liquid solution. Many are designed to simulate smoking implements, such as cigarettes or cigars, in their use and/or appearance, while others are considerably different in appearance.
Along with the battery, the atomizer is the central component of every personal vaporizer. Although many kinds of atomizers are in use, they generally consist of a small heating element responsible for vaporizing liquid, as well as a wicking material that draws liquid in.
