If you're on campus or in airports often, this backpack has your name on it. We see plenty of "tech" backpacks and messenger laptop bags, but why do we think this might be one of the best backpacks in the market for laptop, smartphone, tech toting travelers? Well, first of all, the Powerbag has more padded pockets and compartments than a hunter's vest, so it's well equipped for carry-on duty. Then the backpack also open and folds flat into a "Checkpoint Friendly" mode for easier airport security screening. But the icing on the cake is the removable, rechargeable 6000mAh battery incorporated inside for quick USB cable charging with tablets, smartphones and other portable USB charging devices. It's a backpack that has your back...your charging back.
