Despite its somewhat chunky size, the SolarPort 4.4 has good intentions. It can output 4.4 watts of juice (via USB) to keep as many as three of your favorite gadgets going when their battery has given up. It even comes with a separate charger that refreshes your AA/AAA batteries. Personally, I think it's a little too big (you might be better off just packing backup batteries), but for true tree huggers, the SolarPort will set you back $119. – Louis Ramirez
