You're using the power of the sun to charge your gadgets. That's kind of awesome. Why keep it to yourself? A new solar charging system from German startup Changers makes your eco-consciousness just as obvious as driving around in a Prius.
The actual charger ventures into familiar territory with a solar module and a battery. It can generate up to 4 watts per hour, enough to fill up the battery in four hours. It is designed to charge smartphones, tablets, and other small electronics.
Normally, a solar charging system would sit quietly by, laboring in silence. Not this one. It hooks up to your PC or Mac by USB, tracks your CO2 savings, and tells all your friends about it over Facebook and Twitter.
The device also tracks your energy production on Changers.com and dishes out credits that can be spent with the company's retail partners. There's no word yet on who those partners are.
The $149 Changers Starter Kit is currently available for preorder, with deliveries starting up within a few weeks. Don't worry, the sun will still be waiting for you.
