Solio Bolt Solar Charger
While the Solio Bolt is marketed toward a wide audience of users and gadgets, it is optimized for Apple devices. The Bolt comes in a small package, and designed to use a pencil or pen to angle the photovoltaic cells toward the sun. The Bolt doesn't pass the charge through the cells to the the devices, rather the solar power charges a battery that's used to charge devices through a USB port. In the event you're in a hurry, or want to make sure the Bolt has a charge to start with, it can also accept and charge through a conventional AC adapter. The bolt will charge anything that accepts a USB connection short of a desktop or a laptop, but it's also optimized for iDevices. A setting on the device allows it to charge at Apple's specifications and can recharge most of the battery on an iPhone 4 or 4S, as well as the newer 5, 5s and 5c.
