With a Voltaic solar panel backpack, you can charge your mobile devices (except your laptop) as you cart them – and your other necessities – around town or across the globe.

Embedded in the outside of the bags are three lightweight, tough, waterproof solar panels which generate up to 4 watts of power – which means quicker charge times and tons of convenience. And each bag comes with a set of 11 standard adaptors for common cell phones and other devices, and a Li Ion battery pack that stores surplus power – so you can charge all your devices when you need to (not just when the sun is up). And if it’s cloudy and rainy outside, you can even charge your bag using an AC travel charger or car charger (both included) – making these bags just as useful on the grid as off.
