Specifically designed for emergency & disaster preparedness, the KA350 Voyager Trek offers different methods to power itself. Those methods include AC/DC adapter (optional), three AAA batteries (not included) and the built-in rechargeable Ni-MH battery which can be charged from the AC adapter, by hand cranking, by solar panel or even by a PC. The solar panel not only can keep the built-in battery fully charged but also provides power for the radio even when no battery is installed.
