Despite my ill ease about battery life on my cell phones and iPod, I haven't bought a solar charger for my mobile devices yet because I don't want another heavy thing to carry around in my bag. But this Soldius 1 Universal Solar Charger for iPods and other mobile devices is so lightweight (just 4 ounces) and small (about 4x3 inches), it'll barely take up any space. It's not only compatible with all iPods, but can also be used with 250 cell phone models, including Nokia, Samsung, Sony-Ericsson, Siemens, and Motorola. It's a low maintenance, fully solar charger that requires no traditional battery and no charging up at home.

It sells for $89.99 (with mobile phone kit), $99.99 (with iPod kit) and $109.99 (with both kits) at mysoldius.com.
