An adapter or adaptor^[1] is a device that converts attributes of one electrical device or system to those of an otherwise incompatible device or system. Some modify power or signal attributes, while others merely adapt the physical form of one connector to another.

The adapter gets power through this port. For the most stable connection, use a USB charging port that's directly connected to a wall outlet and provides at least 5W (5V/1A) of power. The adapter can only connect to one display at a time. Before connecting to the adapter, connect your device to Wi-Fi. Adapter is freeware (100% free software). Unlike other free apps, Adapter is lightweight and comes with a completely spam free installer that doesn’t install toolbars or gunk up your computer. Adapter won’t add obnoxious watermarks to your output. There are no limits or restrictions on Adapter.

Travel adapters[edit]

Many countries with ties to Europe use 230-volt, 50 Hz AC mains electricity, using a variety of power plugs and sockets. Difficulty arises when moving an electrical device between countries that use different sockets. A passive electric power adapter, sometimes called a travel plug or travel adapter, allows using a plug from one region with a foreign socket. 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.

This AC1200 USB 3.0 adapter, with high-gain antennas, can make even your older Windows ®-based laptops and desktops connect at the speed of 802.11ac. And with USB 3.0, you can connect 3x faster than USB 2.0. Noun a person or thing that adapts. A connector for joining parts or devices having different sizes, designs, etc., enabling them to be fitted or to work together. Also called plug adapter, adapter plug. A device that connects an electrical plug to an outlet that has a different plug shape: Last time I traveled, I brought the wrong adapter.

AC-to-DC adapters[edit]

An 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. Small, detached power supplies for consumer electronics are called AC adapters, or variously power bricks, wall warts, or chargers.

Computer adapters[edit]

A host controller connects a computer to a peripheral device, such as a storage device, network, or human interface device. As a host controller can also be viewed as bridging the protocols used on the buses between peripheral and computer, and internally to the computer, it is also called a host bus adapter. Likewise, specific types may be called adapters: a network interface controller may be called a network adapter, and a graphics card a display adapter.

Adapters for external ports[edit]

Adapters (sometimes called dongles) allow connecting a peripheral device with one plug to a different jack on the computer. They are often used to connect modern devices to a legacy port on an old system, or legacy devices to a modern port. Such adapters may be entirely passive, or contain active circuitry.

A common type is a USB adapter.

One kind of serial port adapter enables connections between 25-contact and nine-contact connectors,^[2] but does not affect electrical power- and signalling-related attributes.
