Slip this solar panel into your pack and be capable of charging anything under the sun. It's about the size and thickness of a tablet, with a 3200mAh onboard battery that stores and delivers up to 5 watts of USB power to your phone, tablet, or other BioLite gear. The integrated sundial tells you where to angle it to catch the most rays, and the 360° kickstand with Optimal Sun System to help you easily align directly with the sun no matter where you've got it set up.
