I’ll admit that I have lusted after Mophie’s Juice Pack Air, especially considering I can somehow go through my battery power on my iPhone 3GS in a matter of a half a day or so. The only problem I’ve had is the bulk: it ads about 3 ounces of weight, and another half inch or so of bulk, bringing it up to a somewhat chunky 3/4″ in height.
Enter Mili and its recently released Power Skin. While its power ratings (at least advertised) are slightly less than the Mophie, the case measures in at 18 millimeters, a hair smaller than its competitor at about .7 inches. Like its competitor, the skin comes in different color combinations: black or white on the outside, and either white, silver, black, orange, blue, or green on the inside.
Mili says it has gotten the product Apple certified to work with either the 3G or 3GS. At a price of $69.95, it’s also $10 cheaper than the Mophie.
Is such a small difference in bulk going to be noticeable? Until I get one in my hands, I won’t be able to say. But it is nice to see manufacturers attempting to deal with the greatest drawbacks of these cases.
