The several types of flameless cigarette lighters include car lighters, wall-mounted lighters and portable lighters. The user manually activates an electronic push-button power source and must wait several seconds for the heating element to become fully warm.
All flameless lighters need an electronic power source. Car lighters receive a 12-volt charge of power from the car battery when pressed in, and other flameless lighters work much the same as a car lighter, heating up at the touch of a button. Stationary flameless lighters are available in wall-mounted battery- or socket-powered versions; portable flameless lighters use a battery.
Flameless lighters contain a metal element that heats up when touched to the power source. NiChrome --- typically the material used for the heating element, chosen for its high melting temperature --- is wrapped into wire coils on the inside of the lighter.
When a flameless lighter heats to the proper temperature, it will push itself away from the heat source. This motion, caused by a thermostatic action where the internal parts of the lighter expand when heated, prevents the lighter from continuing to heat.
