Solio Bolt

We know $70 can buy you a lot, but wouldn’t you rather pick up a device that can harness the power of the sun to charge your power hungry devices? Weighing a mere 5.3 ounces, the Solio Bolt  ($70) features two high-efficiency solar panels, an on-board battery that can hold enough charge for two smartphones up to a year, and an included pencil to prop the Bolt up and for… um, writing stuff down. Simply connect your drained device to the Bolt using your device’s USB cable to charge. When the Bolt needs recharging, lay out facing the sun, of course, or plug it in to an outlet or a USB port.
