9v 1amp Power Adapter For Arduino Power Supply

AnAC adapter,AC/DC adapter, orAC/DC converter[1]is a type of externalpower supply, often enclosed in a case similar to anAC plug. Other common names includeplug pack,plug-in adapter,adapter block,domestic mains adapter,line power adapter,wall wart,power brick, andpower adapter. Adapters for battery-powered equipment may be described aschargersorrechargers(see alsobattery charger). AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power frommains 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 withbattery-powered equipment, where the supply, when plugged in, can sometimes charge the battery in addition to powering the equipment.
