cool, liek a backup battery meets a wifi hdd/ssd. I have a patriot gauntlet node with 256 gig ssd and ravpower 10,000 mah battery which is great when needed but they are pretty big so i can't always bring them everywhere. given the dimentions this might do for a pocketsized replacement... nto as much functionality but as somethign to slip in a pocket with a cellphone its cool tech i approve
