Our newest purchase is a small solar panel to power phones and tablets. It folds up for storage, weighs just over 2 lbs and you plug your phone into it with a USB cable. We bought it on Amazon for $120. So far, I have used it three times and it works really well for both Jay’s Blackberry and my Samsung. I have even used it on a day that was overcast and, although it took longer to charge, it still brought my phone and tablet up to 100% power.
