Solar Paper
YOLK
Solar Paper is the thinnest and the lightest ultra-high-efficiency photovoltaic charger in the world. It can charge all types of devices that can be charged by USB cables, such as smartphones, tablet PCs, walkie-talkies, flash lights, portable gaming devices, cameras and batteries. On a sunny day, a smartphone can be fully charged in two hours and 30 minutes, which is more or less the same time it takes to charge the phone by tethering it to a wall outlet. The product is modularized, so users can increase or decrease the panels to adjust the power, and each panel is magnetically connected for easy adjustment.
