While one may assume that the above device is simply a USB flash drive in disguise, it's actually quite a bit more useful
than that. You see, this rechargeable USB battery (á la the USBCELL) actually fits into any device that readily accepts AA cells, making it quite possibly the most 1337 (not to mention affordable) rechargeable cell
we've ever seen. Reportedly, it takes around four hours to juice one up, and while we've no idea how many channels you can flip through on a set of these bad boys, at least they're sold in pairs. Pick up a pack (or two, or three) now for $7.51/set.
