Charge Your Mobile Phone With Your Backpack

Along the lines of the Solio H1000, we have backpacks where the solar panels are built-in. The Voltaic Backpack has 3 sets of solar panels, which can capture up to 4 watts of power. That's enough to charge a cell phone and many other portable electronic devices.
The Voltaic Backpack includes a massive 4400 mAh battery to store all that sun juice, 11 different adapters so your gadget can take a sip, and 1850 cubic feet of storage space. Given my experience with the Solio H1000, however, I wonder how practical this ends up being. On the plus side, you can charge the battery in the backpack from the car or an AC plug. Even if you live in the Pacific Northwest like I do, this backpack can still be useful.
It's a bit pricey at $229, but if you want to always be able to charge your mobile devices, this backpack is for you.
