| has gloss | eng: The AC adapter is a type of power supply - typically those that are embedded in an over-sized AC plug. Other names include plug pack, plug-in adapter, adapter block, domestic mains adapter, or power adapter. Informal terms include wall wart, wall cube and power brick. These are typically packaged with electrical devices that do not contain their own power supply. This can be for reasons of size of the device, keeping a source of heat remote from the device, electrical noise isolation, making one device for international sale with a variety of power sources; and due to the economics of getting devices including an internal power supply certified by government regulatory bodies, such as the FCC in the United States. |
