ISO 4165

Comparison of (L to R) two Powerlet plugs, one combination plug, and one Cigar Lighter Plug

ISO 4165is a standard adopted by theInternational Organization for Standardization(ISO) that describes a double-poleDCconnector to supply between 12 and 24 V DC at up to 12ampsto appliances in vehicles. Although roughly similar in design to anautomotive accessory receptacle,the ISO 4165 connector is shorter and smaller in diameter. It was originally a standard fitting on all the German military vehicles duringWorld War II.

The body (which remains outside the receptacle) is 20 mm in diameter. The resilient neck must mate with a 12 mm diameter hole. The center pin is 5 mm in diameter.

The ISO 4165:2001DC connector is also known as theBMWAccessory plug, as it is used onBMW motorcycles;as the Powerlet connector, named after a firm that produces them; and, in Australia (where they are popular in mobile power applications, including 4WD and Caravaning), as the Hella plug, or Merit plug.

At least one manufacturer sells a plug that combines a cigarette lighter plug and a powerlet, in much the same way that combination auto/airplane notebook computer power adapters combine a cigarette lighter plug and an ARINC 628/EmPowerplug.
