Solio Magnesium Solar Charger

This pocket-size solar charger unfolds like a flower to reveal panels that suck sunlight and turn it into electricity. Throw-away batteries can be a thing of the past on wilderness trips: With the right adapter, a Solio sitting in the sun can repower virtually any electronic device — from an iPod to a camera to a GPS device.

The unit comes in a draw-string hemp pouch and is made with a shell of tough magnesium alloy marketed to stand up to abuse where another case could crack. The Solio Magnesium Edition solar charger costs $169.95. www.solio.com
