Unofficial iDevice chargers have taken the form of everything from the hand crank to to the camp stove, and now it seems that Apple is getting in on the act too by taking out a patent for portable solar panel chargers. The patent application — filed with the US Patents & Trademark Office — details a power management system incorporating a solar panel accessory, compatible with both Macs and iDevices, and potentially attached by way of a USB connection. By turning solar energy into electricity, this could then be used to charge future iPhones or MacBooks without the need for a mains power charger.
