Sunlight = free, electricity = not free, so doesn’t it seem like a no-brainer to charge up your gadgets and small electronics using a solar charging device? That’s exactly the thinking behind the Ray, which uses the sun’s rays to juice up iPhones, iPads, iPods, most cameras, and a plethora of non-Apple cell phones. The popular item has not even technically been released yet (it’s available for presale) but in just 1.5 days, it has already amassed 400 pre-orders. The ray operates via a standard USB cable and can easily be used while hiking, camping, hunting, fishing, on a plane, or just in the car as a cell phone battery backup.
