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 ...
Like the IEC 62735, this connector was designed to replace the IEC connector used in computer power supplies so that they can be operated from 380–400 VDC instead. Introduced in January 2009, [ 22 ] it arrived before the competing IEC standard, however despite this it has not seen widespread use.
