Chicago-based electronics company YOLK has launched a Kickstarter campaign for Solar Paper, the world’s thinnest and lightest solar charger that can charge your smartphone within 2.5 hours. Designed for easy use, the ultra light weight solar charger automatically resets itself to continue charging your device even if a cloud passes overhead and the voltage drops. If it’s not too bright out, or you need additional power, extra panels can be attached via magnets upgrading the device from a 5w to a 10w charger.

Devices are connected via USB cables, so it’s virtually compatible with any Apple and Android product, GoPro cameras, speakers, Bluetooth devices, and more. Keep up with the Kickstarter campaign here.
