These new Voltaic Solar backpacks, in multiple styles, as we see above, will power your gear using the healing rays of the sun. What you see is the Pouch, the Messenger, and the Daypack. All of them feature a 3-cell solar array and can pump out 4 watts of power to charge phones, PDAs, rail guns, and digicams. No laptop powering, apparently, which would be really the best.
