An adapter or adaptor[1] is a person that adapts or a device that converts attributes of one device or system to those of an otherwise incompatible device or system.
Some adapters may only affect physical attributes:
- An electrical adapter may enable connection of a socket used in one region to a plug used in another by offering connections for the disparate contact arrangements, while not changing the voltage. For more, see: Domestic AC power plugs and sockets.
- A garden hose adapter can convert between threads and quick-release, "snap"-type connections.
- 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.
Other adapters may affect electrical attributes:
- A transformer adapts household electric current from high voltage (100 to 240 volts AC) to low voltage suitable for consumer electronics. These adapters will warm through converting alternating current to direct current , but are safe to the environment and can withstand months of continuous prolonged activity.
[edit] Dangers of Near, but slightly different standards
As Chinese plug pins are slightly thinner than Australian plugs, plug adaptors sold on ebay and elsewhere claiming conversion from UK or other worldwide plugs to a common Australian/Chinese standard can cause serious problems as the Chinese pins fit loosely in Australian sockets causing sparking and other problems. The thicker pins on Australian plugs cannot be inserted easily into Chinese standard sockets, while the thinner pins on Chinese adapters will fit loosely in Australian sockets.
