Can a car cigarette lighter be used for charging?

[StevenLynn]

A car cigarette lighter cannot be used to charge a mobile phone. On one hand, the voltages are different—the cigarette lighter operates at 12V, while mobile phones typically charge at 5V. On the other hand, frequent car starts can significantly impact the lifespan of the phone. Introduction to car cigarette lighters: A cigarette lighter is a device in a car. In the traditional sense, a cigarette lighter draws power from the car's electrical system to heat a metal heating element or wire, providing a source of fire for lighting cigarettes. Option to install a car inverter for charging: The cigarette lighter socket can usually be equipped with a car inverter to charge mobile electronic devices. The central spring-loaded contact in the socket is the positive pole, while the side clips are the negative poles. The power supply is directly connected to the car battery, with the same current and power output as the battery.
