battery-operated
Needs portable power
Battery-operated describes devices that run on batteries rather than being plugged into an electrical outlet: a battery-operated toy, battery-operated smoke detectors.
The term often implies portability or convenience, since the device doesn't require a cord.
In suggestive contexts, it's a euphemism for vibrators and similar devices: her battery-operated boyfriend.
