AC Power Adapter | Routers | All

An AC adapter, AC/DC adapter, or AC/DC converter is a type of external power supply, often enclosed in a case similar to an AC plug. Other common names include plug pack, plug-in adapter, adapter block, domestic mains adapter, line power adapter, wall wart, power brick, and power adapter.

Adapters for battery-powered equipment may be described as chargers or rechargers (see also battery charger). AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power.

The internal circuitry of an external power supply is very similar to the design that would be used for a built-in or internal supply.

External power supplies are used both with equipment with no other source of power and with battery-powered equipment, where the supply, when plugged in, can sometimes charge the battery in addition to powering the equipment.

Alternatively known as an AC/DC adapter, AC converter or charger, an AC adapter is an external power supply used with devices that run on batteries or have no other power source. AC adapters help reduce the size of a laptop computer by alleviating the need for a standard sized power supply. As shown in the image, an AC adapter is made up of a central unit which draws power from an AC outlet. It then converts the power to DC that is used by the computer, and a second cord that plugs into the computer.

Each AC adapter has a specific power rating, measured in volts or watts that it can handle and output to an electronic device. Because of the power rating and the type of plug on the end, an AC adapter is not universal and can only be used with devices with the same requirements and connector.

If necessary, a universal AC adapter can be used, which is designed to work with many devices, having multiple types and sizes of plugs for connectivity to those devices. A universal AC adapter may also have a voltage or wattage range that it can output, like 100 volts to 240 volts or 70 watts to 125 watts, providing for a greater range of compatible devices.
