This mains power plug travel adapter allows British plugs to be connected to American or Australian sockets.
An adapter or adaptor is a device that converts attributes of one device or system to those of an otherwise incompatible device or system. The term is often used to refer to AC adapters.
Some adapters may only affect physical attributes. An electrical adapter may enable connection of a plug used in one region to a socket used in another by offering connections for the disparate contact arrangements, while not changing the voltage. For more, see: AC power plugs and sockets. A garden hose adapter can convert between threads and quick-release, "snap"-type connections. For computers and related items, one kind of serial port adapter enables connections between 25-contact and nine-contact connectors, but does not affect electrical power- and signalling-related attributes.
^Both spellings are used in both British and American English.
