Solio, whose motto is "Plug into the sun," sells several solar chargers for on-the-go gadget toters. The Solio Universal Hybrid Charger, which comes in many colors, including pink, can work from the wall socket or by soaking up the sun. One hour of sun time gives you one hour of play time on a digital music player. As a bonus to the green buyer, the $99.95 charger is 100 percent carbon-neutral, as the company offsets its energy use by planting trees in protected biodiverse forests.
