The electronic cigarette gives the user the option of a manual or automatic battery. The manual battery contains a small pushbutton that will control when the unit turns on or off. The automatic battery works with a micro-sensor and will automatically turn the unit on whenever you inhale on the end. The manual battery offers the user a new level of control and flexibility, while the automatic battery offers the ease of use just like a real cigarette. The main benefit of the manual battery is the user can take a longer "drag" with no cut-off time.
