Cellphone-shaped solar charger

ultimate solar charger

We have no idea why one would want to build a solar-powered cellphone charger that is shaped like a cellphone (making you stand around holding two devices tethered to one another, a la the Nintendo Revolution controller), but when insipiration struck Roland Kleinfeld on a visit to China, he simply had to bring the Ultimate Solar Charger to life. Compatible with about 70 models from major cellphone manufacturers, Kleinfeld's charger has drawn criticism concerning its ability to prevent battery leakage and overheating when exposed to direct sunlight. Even so, once the wheels of industry start cranking, it's hard to slow them down, and so the $25 Ultimate Solar Charger is available for purchase immediately.
