This rechargeable USB AA battery concept by Wonchul Hwang comes with a built-in USB jack that can be plugged into any USB power source, either from a computer, laptop or from a USB power adaptor. When it is fully charged, it can be used just like any ordinary AA battery either for day to day use or simply as a form of backup power source.

Apart from its capability as a rechargeable battery, it also comes with memory storage. With a built-in USB jack, all that is needed is for it to be plugged into a compatible device and it can be used for memory storage. The only drawback to this design is that you won’t be able to use both of its function at the same time.

An interesting design for a portable rechargeable battery that comes with built-in memory storage.
