It looks like Mophie may have some competition with its well-received Juice Pack Air for the iPhone 4 as rival Dexim as released a very competitive offering in the form of the Super-Juice Power Case. As its name implies, Dexim’s Super-Juice Power Case offers a hard case shell protection for the iPhone 4 and integrated battery that measures in at 2200 mAh, giving you an additional 6 hours of talk time on your iPhone 4 beyond your Apple smartphone’s battery. Moreover, where it bests Mophie is that it offers an integrated kickstand, and why not? With that much juice available for the iPhone to sip, why not watch a few extra movies on the thing or angle the phone better for FaceTime chatting? While Dexim still hasn’t announced availability nor MSRP for the Super-Juice Power Case yet, they did show it off at a CTIA show and I got a chance to play with it. It does feel solid and looks good on the iPhone 4, though Mophie’s iteration more closely resembles Apple’s design aesthetics.
