I like this, it’s a really nice add on to the iPhone, and it should be made for other devices as well. It’s a battery extender for the iPhone, that only increases the form factor of the iPhone, slightly, offers a power up that is intelligent, and some added protection. The battery extender, powers down before the phone, and offers

250 hours of standby time, 8 hours of talk time, 6 hours of internet use, 7 hours of video playback or 24 hours of audio playback. The juice pack itself can be charged using your iPhone’s charger. The intelligent power distribution ensures that the iPhone drains out the juice pack first. When you’re done with it, you still have a fully charged iPhone.

It would be great to see a wider range of these, supporting other devices. Power supply supplementation devices that are stand alone, are needed accessories that supercede extended batteries, which really make your device FAT.
