PowerFilm USB+AA Portable Solar Charger
Solar Panel Review takes a gander at the PowerFilm USB+AA Portable Solar Charger. Here is a review from Amazon….The PowerFilm USB + AA charger is probably the best product and design I have seen in terms of AA solar chargers, especially for backpackers. Stores like REI and EMS need to carry this charger. Basically, this is 2 devices in 1. It is a solar charger for NiMH batteries (2 NiMH Sanyo 2000mAh batteries come with the product). It is also a voltage transformer that takes the 2.4v of the NiMH batteries and ramps it up to 5v allowing you to charge a USB device (like a cell phone or iPod) using the charged batteries, even when it is NOT in the sun. This means that you can lash the unit onto your backpack or car dash without having to tether your phone to it all day, and then draw from the stored energy in the batteries at night. I charged two batteries in the sun with no problem and then charged an iPod Nano 2G while the solar panel was folded up, and it work perfectly.

1. Folds up compactly to fit into a pocket.
