If you’re highly mobile, if you travel to trade shows or just walk around campus all day, or perhaps if you take long plane flights, you already know that for all the great features of the Apple iPhone, extended battery life ain’t one of them.
Indeed, when we recently attended the 2009 Consumer Electronics Show it was by the end of the first day when it became apparent that the iPhone just didn’t have the battery longevity we needed.
That’s why we decided to test out extended iPhone compatible batteries at the show, seeking out vendors and asking them for samples and demo units. Most of them were not very good and I’ll note that when I tried one that was powered by a pair of AA batteries it died before even completing a single charge. Useless.
Fortunately, I did find one that I was very impressed with, the Power Air Zpowerpac13 and have subsequently been sent a second that’s also very good, the morphie juice pack.
