This weather-resistant suitcase-style solar battery charger can take a little shower, and will charge four AAA or AA batteries in 1-2 days of sun.
Higher capacity batteries (newer C and D cells) will take a lot longer in this charger - roughly 6 hours of charging for every 1000 mAh of battery capacity.
Charges NiMH or NiCd AAA, AA, C or D rechargeable batteries, four batteries at a time. Also features a 7V DC multi-plug output to charge 6V devices.
Charges at 160 mA charge rate, measures 7" X 7" X 2".
Note: We do not really suggest using this solar charger if you are using C batteries or D batteries as their high capacity results in a very slow charge.
