We're not sure if Brando's version of the external iPhone battery pack bests the others we've seen in performance, but it's definitely the cheapest by far. At $25, it's a whole $18 cheaper than the iPhoneck, and half as costly as Macally's PowerLink. Is it any good? No clue yet. But it's cheap, which is all some people care about.
