Battery radios were made clear into the 1950s or so for use on farms
where there was no commercial AC power. *Also there were portable tube
radios that ran on batteries.

Take a Windmill or Water Wheel plus
an old Car/Truck 6 VDC Generator and
Regulator and a 6 Volt Battery.

Lot of 'far out' rural and country places
still had old 12 Volt Lights for use for a
few hours at night.
