    IEC Technical Specification 62700: DC Power supply for notebook computer is an IEC specification of a common standard for external laptop computer AC adapters.Laptops and AC adapters following this standard will have interchangeable power supplies, which will enable easy reuse of used power supplies (thereby reducing electronic waste) and make buying a new compatible power supply for a laptop ...

  3. AC adapter - Wikipedia

    en.wikipedia.org/wiki/AC_adapter

    An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.

  4. Power supply unit (computer) - Wikipedia

    en.wikipedia.org/wiki/Power_supply_unit_(computer)

    The desktop computer power supply converts the alternating current (AC) from a wall socket of mains electricity to a low-voltage direct current (DC) to operate the motherboard, processor and peripheral devices. Several direct-current voltages are required, and they must be regulated with some accuracy to provide stable operation of the computer.

  5. Power supply - Wikipedia

    en.wikipedia.org/wiki/Power_supply

    An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics because of their safety; the hazardous 120 or 240 volt main current is transformed down to a ...
