The unit uses a rechargeable Ni-Cad battery: a rechargeable battery that has the ability of recharging over 500 times. This remarkable radio and light recharges these batteries using either the hand crank and/or solar panel to charge them. You can simply charge the battery in the sun, charge it in artificial light, or charge it using the hand crank. After the battery has been fully charged and discharged, one minute of hand cranking produces 10 minutes of play. The radio is compact with dimensions of 7-1/2 inches in width, 5-1/2 inches in height, and 2-1/2 inches in depth. To charge in car, 4.5 volt DC auto lighter can be purchased separately.
