Was ist eine Zigarettenanzünder-Buchse?

The cigarette lighter receptacle in an automobile, ursprünglich für den Betrieb eines elektrisch beheizten Zigarettenanzünders konzipiert, wurde zum De-facto-Standard-Gleichstromanschluss für die Stromversorgung tragbarer Zubehörteile, die in oder in der Nähe eines Automobils verwendet werden. While the cigarette lighter receptacle is a common feature of automobiles, as a DC power connector it has the disadvantage of relatively low current rating and poor contact stability.
Examples of devices that can be operated from a cigarette lighter receptacle include lights, fans, beverage heating devices, and small motorized tools such as gas compressors for inflating tires. Many portable electronic devices such as music players or mobile telephones use a cigarette lighter receptacle to recharge their internal batteries or to directly operate from the vehicle electrical system. Adapters for electronic devices may change voltage to be compatible with the supplied device. Devices that require alternating-current mains electricity can be operated with a plug-in inverter.
