What is a Cigarette Lighter?
1 Answers
A cigarette lighter is a tool used for lighting cigarettes. It is a component found in all vehicles, designed to provide a convenient ignition source for drivers who smoke. The power supply is typically 12 volts DC (may vary depending on the vehicle model), with the central spring-loaded contact as the positive terminal and the side clips as the negative terminals. The cigarette lighter is directly connected to the vehicle's battery, sharing the same current and power specifications. Beyond its primary function of lighting cigarettes, the cigarette lighter can also be equipped with a car power inverter, which converts the vehicle's 12V, 24V, or 48V DC power into 220V 50Hz AC power, suitable for powering common electrical appliances. The cigarette lighter socket functions similarly to a household multi-outlet power strip, connecting to the vehicle's power supply via a plug and providing multiple cigarette lighter ports for electronic devices.
