    It is bigger and clumsier than I had anticipated (not sure how, but it looked smaller in the store - it’s the size of an old-skool car-fone). It is extremely heavy for being so thin. I was told that it holds 8 full iPhone charges. That’s being exceedingly generous. It holds maybe 6, at most. But, for a guy on the go, an aux battery with multiple charges is a life-saver. Plus, I was told that I can leave it in my bag for weeks at a time without needing a recharge and it will hold the juice. Jury’s still out on that one.
