• AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
• The internal circuitry of an external power supply is often very similar to the design that would be used for a built-in or internal supply.
• When used with battery-powered equipment, adapters typically charge the battery as well as powering the equipment.
