PowerFilm USB AA

The perfect portable solar charger for everyday device charging!

Need a charger that can charge your cell phone? Your portable gaming device? Your iPod™? PowerFilm has created a solar charger that handles direct charging of most everyday portable electronic devices…and it charges batteries, too.

The USB+AA Foldable Solar Charger will charge 2 AA batteries from fully spent to full charge in 4 hours (in full sun). In addition to battery charging, utilizing the universal USB port and working with 2 rechargeable batteries (included) allows for direct charging of most micro USB devices, like cell phones, smart phones, and iPods.

Built with the same standards as PowerFilm's full line of solar chargers, the versatile, lightweight USB+AA Foldable Solar Charger offers several benefits:

• "Turns on" sooner and "turns off" later
• Resists point damage
• Powers even in 100% darkness through the USB port because the 2 included rechargeable batteries act as storage devices for the energy absorbed by the solar panels during the day
