Fewer and fewer devices in our life rely on batteries, but they are still prominent enough to insure that every now and then, you’ll fumble through your things looking for that final set of AA’s you are sure you had, and juggling between the ones in the Xbox controller and the TV controller as needed.

Rechargable batteries have been around for years to prevent scenarios just like those, and while they’re impressive technology in their own right, the classic rechargeable set up doesn’t quite feel up to speed with the modern tech world, and looks out of place in any home, not to mention the inconvenience it puts on travelers.

There is a design out there for a AA battery that looks to alleviate the modern issues with rechargeable batteries, by outfitting a standard AA battery with a USB plug-in. The set up would allow you to plug the battery into any USB port, and recharge it without any additional equipment required. Even better, the battery itself doubles as a 4GB USB flash drive for additional file storage.

Perfectly built for traveling, or really any use, this is not an idea without precedent, but it’s never looked more effective than it does with this design. Unfortunately it is just a design at the moment, and any plans past that concept are just that.

The inventor, Wonchul Hwang, sounds committed to making this concept work though, which is perfect, as so long as this device’s price doesn’t break the bank, everyone is going to want a couple of these around.
