Plug in AC-DC adapters are also known as AC Adaptors or AC-DC converters and are a type of external power supply. Some electrical appliances require power but lack the internal components to derive the required voltage and power from mains power. This is where an AC adapter is used to convert the AC current into DC voltage.
