AA USB concept battery features built-in USB storage and charging

We’ve seen AA batteries that could be juiced up by a USB port before, but what about a AA battery that features a USB flash drive inside it? This concept battery features a USB port at one end that can be retracted, adapting to the scenario you need it for. In case you’re left wondering if there is enough juice inside it or not, you could check the electricity indicator that is available on the side. Costs aside, we’d love such a concept battery to be turned into a reality, not least because we want more flash drives in our lives.
