Brighten Up and Get Outside With Our May Must Haves

If you prefer using the GPS in your iPhone to track your long runs or rides but hate that it completely drains your battery, you're going to love this sleek Otterbox Resurgence Power Case ($100) as much as I do. It more than doubles your battery capacity! All you need to do is plug in the USB cable, and it'll charge your phone first and then the case's battery. If you want to know how much battery life you have left, just tap the button on the back and each light section represents 25 percent of case power. And because it's an Otterbox, your phone is protected against bumps and drops.
