   The voltage of the power outlet is usually near 12 V DC, and may be elevated between 13.5 V to 15 V while the engine is running. On trucks, the voltage of the power outlet may be near 24 V DC. The 12 V power circuit is protected by a car fuse, often rated at 10 to 20 amperes, which provides 120 to 240 watts of power. Large appliances such as ...

   The polarity for 12 V DC sockets is center pin positive (+), outer collar negative (−). Reversed polarity will damage some electronic devices. Although the nominal voltage of a 12 V lead acid battery is 12 V DC, when the engine is running the car's battery charging system will bring the system voltage to 13.8 V DC or higher. [10]
