The Solio Bolt is one of the most unusually shaped mobile solar chargers you can find. IT comes with two panels that rotate to be best pitched toward the sun. It comes with a 3.7 volt/2000 mAh lithium-polymer battery. Bolt weighs 5 ounces, and it measures 4.7 inches by 1.3 inches by 2.5 inches. It takes up to 9 hours to full charge; once charged it can juice up your GPS receiver, flip-phone or digital camera up to three times. It can charge an e-reader or smartphone twice. The Bolt carries a list price of $70.
Logitech went solar with it wireless keyboards this year, offering models for both Macintosh and Windows systems. The Logitech Wireless Solar Keyboard uses either sunlight or ambient lighting to keep charged up, working for up to three months on a full charge. (That's pretty accurate; I got mine in August in only recently had to make sure to leave the keyboard out so it could charge up again.) The keyboard currently carries a list price of around $71.99. It needs a unifying receiver to connect to your computer.
