Cameras—as well as GPS devices, e-readers, smartphones, and all pocketable Apple products—need to be recharged all the time. Unfortunately, you aren't near an electrical outlet all the time. Thankfully, Solio has a line of durable, portable chargers that let you plug into the power of the sun. One of the coolest: The Solio Mono, which is small enough to toss into your camera bag but can hold enough juice for a Canon PowerShot to grab 215 photos. The Mono can be fully charged by the sun in 17 hours or via a USB connector or optional wall charger.
