An AC adapter or AC/DC adapter (also called a wall charger, power adapter, or informally wall wart, or, in some configurations, power brick) is a type of external power supply, often enclosed in a case similar to an AC plug. AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
