Solar panels keep getting lighter and tinier—good news for rugged on-the-go types who can charge their devices on the trail with sun-fueled chargers. And this particular solar charger on Kickstarter is so thin, you can slip it in your Lonely Planet while it feeds your phone battery.
It’s called Solar Paper: 7.5 inches long, 3.5 wide, and .15 thin. There’s a .45-inch thick USB charging port at the top, which sticks out of your book like a bookmark that sucks in that precious sunlight.
One of these panels weights 4.5 ounces and equals 2.5 watts, and you can connect more panels with magnets for more power. In good weather, two connected panels can fully juice an iPhone 6 in about two-and-a-half hours. You can connect up to four foldable units for a total of 10 watts, capable of charging an iPad Air 2 to 100% in four hours.
A nifty feature is Solar Panel’s auto restart. With similar gadgets, a passing cloud or sudden shadow shuts the charger down, forcing manual reboot. But Solar Panel resets that automatically. You can use it to charge anything that connects with USB: GoPro, external batteries, Bluetooth speakers, digital cameras, and so on.
Developed by solar company Yolk, the project’s raked in over $320,000, way past its modest $50K goal. A month left of funding still remains. The team hopes to have the first batch deliverable by September.
The past couple years have welcomed a whole rucksack’s full of portable, solar-powered gear built for the outdoors: like flashlights, watches, and bikes. May as well put the giant star to good use.
