xs_Solar-Powered iPod Charger

This solar-powered iPod charger is portable and perfect for those times when you need to charge your iPod but are not near a power source. It works with the iPod mini, 4th Gen iPod, iPod Photo, U2 iPod, 5th Gen iPod Video, iPod nano (all generations), iPod touch, iPod classic and the 1st Gen iPhone.
This solar power charger is not appropriate for the 1st/2nd Generation (the earliest models produced in 2001-2002), the 3rd Generation iPod or the iPhone 3G models.

Simply open the case and allow the two halves to soak up the rays. After a few hours, a powerful 1200 mAh lithium-ion battery inside the charger will be fully juiced up. Connect the solar-powered charger to your iPod and you are ready to roll!

Perfect for the outdoors. Includes LED power indicator.
