OtterBox Resurgence Power Case for iPhone 5S has massive battery built in

One of the worst things about smartphones is how quickly their batteries die. An entire industry has popped up to solve the problem and it seems that there’s a new external battery pack and charging phone case released every day. Now, OtterBox is joining other case makers with its streamlined Resurgence Power Case for the iPhone 5 and 5S. 

The Power Case comes with a 2,000mAh battery built into the back, which provides 2x battery power and one extra charge for your iPhone. The case also features a front-facing LED at the bottom right of the case to let you know how much your iPhone’s battery has charged. The indicator light is divided into four 25 percent increments, so you can see when your iPhone is 25, 50, 75, or 100 percent charged. As soon as your iPhone reaches full battery, the case turns off to preserve its own internal battery for the next time you need a charge.

In keeping with OtterBox’s reputation for making some of the most high-quality protective cases, the Resurgence Power Case is built to withstand a lot of drops and crashes. Even though the Power Case doesn’t look as impenetrable as the Defender case, OtterBox says the polycarbonate the case is military rated and survived rigorous testing. The case is designed to absorb energy and reduce the force of impact dramatically. Considering the fact that it has a large battery inside, the Power Case is relatively light at 3.05 oz and measures 5.65 x 2.55 x 0.69 inches.


The case is made up of two parts: the colorful back where the battery is located and a front part that snaps on to keep the iPhone secure. The back of the case comes in black, glacier, teal shimmer, or satin rose. The front part is either black or white, depending on which back you choose. Teal shimmer and glacier come with the white front, while black and satin rose come with the black front. OtterBox’s new case is now available on the company’s website and at a few retail locations for $100.

Correction on 06-27-2014: This article initially stated that the Resurgence case offers 2 extra charges for your iPhone. It has been updated to reflect that the case holds just one extra charge, but offers 2x battery power to the iPhone 5S.
