The Yeti 150 charger box by Goal Zero is an electrical charger which includes AC, 12V, and USB ports. The only downside to it is that it weighs about 12 pounds. But it will be able to cover just about any gadget you have.

The 150 watt hour battery can be juiced up in just 15 hours of sun exposure using in attachable solar panel. The kind of stuff you'll want to have when you're in the great outdoors! [Goal Zero]
