A modern clockwork radio with crank in winding position
A batteryless radio is a radio receiver which does not require the use of a battery to provide it with electrical power.
Originally this referred to units which could be used directly by AC mains supply (mains radio); it can also refer to units which do not require a power source at all, except for the power that they receive from an ambient radio source, such as radio waves.
