Green technology is expanding and becoming more efficient than ever. Yolk introduces a green way to keep your smartphone charged. Solar Paper’s name describes it all, a thin and light solar panel that charges your phone on a sunny day. The reason Solar Paper dominates the solar charger market is due to the capability to automatically adjust based on the natural light provided. In about 2.5 hours, you can charge your iPhone or other smartphone. While this may seem like a long time, it is ahead of the curve in terms of efficiency and size. To improve the charge time, simply add panels by the magnets on the panel’s outer edge. This is especially useful if you want to charge an iPad pro or something of its kind.
