If you are out in the woods or out camping and you need to charge a camera, cell phone, or any personal electronic devise, you may want to check out this Brunton Freedom Portable Solar Panel 2200 mAh Battery. This thing is great, I was out in the boat for fishing opener this weekend and need to charge my GPS so I busted out my new portable solar panel and it charged it right up. It doesnt take up much space in a bag and real simple to set up.
