To be completely blunt, I've been skeptical of "battery cases" in the past. I haven't exactly had a clean run with this particularly breed of case, and I was extremely worried that the one I'm writing about here was going to have the same issues. If I've said it once, I've said it a thousand times - I was wrong.
Design and build quality
The first thing I was wrong about was the quality of the actual case. When I learned that the case actually housed a battery powerful enough to give your iPhone a full recharge, I was expecting one of two things - a ridiculously thick case, or a hugely extended iPhone. The case designers went for both, but in very subtle ways - the phone is slightly extended, and slightly thicker, but nothing serious. The added length is due to the "dock" attachment at the bottom, and the thickness is because of the battery that is spread across the back of the case.
Protection is minimal, but it will stop the basic bumps and bruises faced by your iPhone, but not anything serious. The design of the case leaves your screen completely exposed to the outside world and all its hazards, while the back of the case is thick enough to protect the phone from smashing.
