The OtterBox name is synonymous with ruggedized iPhone cases, but not with battery cases — something the company worked to change with the iPhone 4/4S Defender iON Series, and the iPhone 5/5s Resurgence Power Case. iON aimed to thoroughly protect an iPhone while automating the recharge process, while Resurgence reduced the automation and protection to make daily use easier. At CES this month, OtterBox launched a new version called the Resurgence Power Case for iPhone 6 ($100), and it’s been redesigned with a collection of small but welcome tweaks.
Whether you’ll prefer Resurgence to Incipio’s excellent offGRID Express (review) depends on what you’re looking for — ruggedization or raw power for the dollar. Like many companies, OtterBox is promising to double the iPhone 6’s battery, but it also has some currently unique benefits to offer. Read on for what makes OtterBox’s latest battery case special.
