Solar Paper, a 2017 CES Innovation Award-recipient, caught our attention this year. Created by YOLK, the Solar Paper is a modular array of ultra-light mini solar panels that can be linked together to create a portable solar array to charge up your small electronics via USB.
The Solar Paper panels snap together with magnets, letting you easily scale the array to your charging needs. Panels also include small holes, allowing you to quickly clip it onto a backpack and charge up while you hike. A two-panel unit is only 9 x 19 x 1.1 cm when folded, and each panel weighs only 2.5 oz. According to YOLK, the Solar Paper is 70 percent smaller and lighter than their closest competitor when comparing it watt-for-watt.
Depending how many panels you link together, the Solar Paper’s output can range from 5 watts to 15 watts. YOLK claims that the basic two panel, 5 watt unit will fully charge a smartphone with roughly 2.5 hours of direct sunshine. The Solar Paper doesn’t have a built-in battery, but you are able to juice up a portable battery bank using its USB port.
