An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
The Type-A plug. This plug has an elongated rectangular cross-section, inserts into a Type-A receptacle on a downstream port on a USB host or hub, and carries both power and data. Captive cables on USB devices such as keyboards or mice terminate with a Type-A plug. The Type-B plug: This plug has a near square cross-section with the top exterior ...
Generic plugs are often named for the pin diameter they are designed to take. Many non-proprietary co-axial power plugs are 5.5 mm (0.22 in) in outside diameter (OD) and 9.5 mm (0.37 in) in length. Two pin sizes are standard in the jacks for this size plug body, 2.1 mm (0.083 in) and 2.5 mm (0.098 in), and the plugs should match.
AC power plugs are also commonly circular, for example, Schuko plugs and IEC 60309. NMEA 2000 cabling using M12 connectors The M12 connector , specified in IEC 61076-2-101, is a circular electrical plug/receptacle pair with 12mm OD mating threads, used in NMEA 2000 , DeviceNet , IO-Link , some kinds of Industrial Ethernet , etc. [ 16 ] [ 17 ]

External power supply could send data about itself (power, current and voltage ratings) to the computer. For example, genuine Dell power source uses 1-Wire protocol to send data by third wire to the laptop. The laptop then refuses a non-matching adapter. [36] Some computers use a single-voltage 12 V power supply.
