Sure, you can just toss an external battery
in your backpack to keep your gadgets powered on the go, but why stop there? Some of the "influencers" over at Quirky
didn't, and have come up with this so-called Trek Support backpack as an alternative. As you can see, it packs a removable "gadget dock," which can itself be charged up and then in turn charge up to three different USB gadgets simultaneously. You'll also naturally get a dedicated laptop sleeve, plenty of pockets, and a TSA-friendly design. Of course, this is a Quirky project, which means it'll just remain a concept unless it raises the necessary funding through pre-sales. Ready to do your part to make it happen? It'll cost you $130 at the source link below.
