The US$69.99 Super-Juice Power case (http://macte.ch/Tox5P) by Dexim is an external iPhone 4 case combined with a 2000 mAh battery. Unlike other cases I’ve seen in this style, Dexim has thought of everything and this is the battery case I’d recommend above all others currently on the market for the iPhone 4.
The battery power is similar to that of the Mophie Juice Pack Plus and claims to supply an extra 2000 mAh to your device to allow for six hours of talk time, 10 hours of video, or 40 hours of music. It uses a micro-USB cable to charge itself and to provide pass-through charging to the iPhone. Three blue LED’s in the back indicate the level of charge the device is providing and a small button in the back can turn off the battery boost when not in use.
The Super-Juice’s strength is in its design particulars. Unlike most other cases I’ve seen in this category, the iPhone 4 is easily removed from the Super-Juice. Release the top hood and the iPhone slides out.
However, the hood stays attached to the case so you can’t lose it. Why other manufactures haven’t taken this step really surprises me. More than one external battery case I’ve had in the past was rendered useless by losing a critical part.
The back of the Super-Juice has a little “kickstand” that can keep the iPhone in landscape mode on a table or another flat surface. This is perfect for watching video on a plane and is a simple little extra that makes all the difference.
My only major complaint is the fact that the plastic of the case has a glossy finish that can become slippery in sweaty hands. I intend to attach a few grip slips to prevent the case from slipping. Since it comes only in white, I might use the grip strips to jazz the color up a bit.
Overall, the Super-Juice Power Case by Dexim is a high capacity external battery and case that keeps you going all day with your iPhone 4 and has subtle design features and extras that make it best of class.
Pros: 2000vmAh battery, kickstand, integrated design so nothing gets lost
Cons: Only comes in white, glossy finish to the plastic.
