This mini solar panel by Brunton collects and stores power, then transfers it to electronic devices as needed. It is ideal for small electronic devices such as phones, GPS, satellite radio or iPod/MP3.
The solar panel can be charged from the sun, electrical outlet, computer USB, or from included DC adapter. 20 hours of sun = full charge - and it KEEPS a charge over months. In our own tests, when used as instructed, the solar panel charged a cell phone 3-4 times before empty.
