MiLi Power (http://www.MiLiPower.com) has unveiled the MiFlip, an US$49.99, foldable smartphone charger. It’s compatible with the iPhone, iPod touch and Blackberry.

The MiFlip has multiple functions filling the need for a charger, battery back-up, and mobile device stand. Its flip design keeps it slim and sleek, not adding unneeded bulk or weight, says MiLi Power Executive Vice President Robert Grossman. The design also provides a built-in kickstand for widescreen movie viewing.

The MiFlip provides up to eight hours of talk, 15 hours of video or 80 hours of music. It uses a mini-USB connector and lets you sync all your data between your computer’s iTunes library and smartphone.
