![]() ![]() ![]() Small, detached power supplies for consumer electronics are called AC adapters, or variously power bricks, wall warts, or chargers.Ī host controller connects a computer to a peripheral device, such as a storage device, network, or human interface device. As other countries supply 120-volt, 60 Hz AC, using a travel adapter in a country with a different supply poses a safety hazard if the connected device does not support both input voltages.ĪC-to-DC adapters A "power cube"-type AC adapterĪn AC-to-DC power supply adapts electricity from household mains voltage (either 120 or 230 volts AC) to low-voltage DC suitable for powering consumer electronics. A passive electric power adapter, sometimes called a travel plug or travel adapter, allows using a plug from one region with a foreign socket. ![]() Difficulty arises when moving an electrical device between countries that use different sockets. Many countries with ties to Europe use 230-volt, 50 Hz AC mains electricity, using a variety of power plugs and sockets. Some modify power or signal attributes, while others merely adapt the physical form of one connector to another. This mains power plug travel adapter allows British plugs to be connected to American or Australian sockets.Īn adapter or adaptor is a device that converts attributes of one electrical device or system to those of an otherwise incompatible device or system.
