Sun backs up battery
What it is: A rugged, water-resistant lithium battery with a built-in solar panel for power on the go. It has a micro-USB input that allows you to charge it before hitting the road. The 2.1A USB output is powerful enough to charge a tablet. When you're out and about, the 6-inch square solar panel allows the sun to give the battery a boost. A fully charged BoostSolar can recharge most smartphones twice and boost the power of a tablet. LED lights indicate both when the battery is charging and how much of a charge is left.
