It's not often we end up stuck without a plug to charger our cell phone, but we do like the idea of the charge being "greener." Enter the SolCell Charger from Silicon Solar, who also produces the solar battery charger we linked to recently. We like the idea of replacing our usual charger with this one because of it's greener nature. At only $29.00 and 6 oz., this small item also comes with another great feature: it has its own battery back-up, so you can charge even when you're not around a light source (i.e. at night when you're sleeping). The SolCell connects to Nokia, Ericsson, Audiovox, Kyocera and Samsung cell phones.
