Solar battery chargers are a great way to save time and money by making it possible to charge a large variety of devices from anywhere as long as the charger is all juiced up.
The convenience is amazing: you can load the charger either from the sun, from a wall outlet or from a USB port on your computer. Since the charge stays for as long as one year, you can take the charger with you and juice up your phone, MP3 player, e-reader, tablet, GPS, or camera no matter where you are.
Solar charges are fast, too. Charging at a similar rate as a standard battery charger, users can expect a typical smartphone to go from zero charge to full in just about three hours.
There are also solar chargers for large 12V batteries, like the kind used in cars, lawnmowers, tractors and boats, as well as solar powered chargers for Ni-Cd and Ni-MH rechargeable batteries.
