With the many features on modern cell phones nowadays such as web browsing, instant messaging, GPS navigation, it’s not too surprising to find that our devices are often out of juice. We’ve already seen plenty of battery packs for Apple’s iPhone, and now a German newsletter spills the beans on an upcoming Samsung Power Pack EBB-U10 which is designed for the Galaxy S. The battery/case should be available in the near future and will offer users an additional talk time of 8.5 hours or an additional 500 hours of standby time. Pricing and availability of this power pack wasn’t mentioned, but it seems like a useful accessory for the Galaxy S.
