Solar Powered Battery Charger Charges 4 D, C, AA and AAA Batteries

This unit will charge four equivalent D C AA AAA sized batteries at any one time. It includes an adjustable stand to assist in positioning for the best angle toward the sun. Can also be used indoors when placed in direct sunlight through a south-facing window. Bright sunlight is not necessary for this unit to work properly, but it obviously works faster when available. Overcast days are fine but it increases the time necessary to recharge the batteries completely.
