BioLite SolarPanel 10+ Foldable 10W Solar Panel with Integrated Battery

The SolarPanel 10+ Foldable 10W Solar Panel with Integrated Battery from BioLite lets you harvest energy from the sun and use it to directly power a phone or device or store the power in its built-in battery for later use. A sundial and kickstand help you position the panel for maximum sunlight, but the battery can also accept a charge via micro-USB when the weather doesn't cooperate. Phones and other small gear can plug directly into the panel's USB-A port for direct charging. The compact folding panel weighs just over a pound and is rated IPX4 splashproof.
