battery-powered
Needs no outlet
Battery-powered describes devices that run on batteries rather than being plugged into an electrical outlet or powered by other means: a battery-powered flashlight, battery-powered toys.
The term emphasizes portability—something battery-powered can operate without a cord or external power source.
