Slip this water-resistant solar panel into your pack and be capable of charging anything under the sun. It's about the size and thickness of a lunch tray, ready to deliver up to 100 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 helps you easily align directly with the sun no matter where you've got it set up. Grab a BioLite BaseCharge and you have a full solar generator for keeping some juice in reserve.
