Worrying about an uncharged phone shouldn't be an issue when you're out connecting with the great outdoors, but the truth of the matter is that a functioning smartphone can be an essential tool in emergency situations. Solar Paper—a sun-fueled phone charger that looks better than most of the options out there—is thin enough to fit among the pages of a notebook, but comes with enough power to fully charge an iPhone 6 with 2.5 hours of sunlight.
The charger also works with GoPros, external batteries, portable speakers, flashlights, digital cameras, and tablets—basically anything with a power cord. Additional panels—which are attached via magnet connectors—can be added for devices requiring more power. The best feature may be the gadget's ability to automatically reset itself when light is temporarily lost. Most solar chargers need to be manually reset as clouds pass and block sunlight.
