The PolarPro PowerPack is a portable battery pack designed for the OtterBox uniVERSE Case (sold separately). It features a rechargeable 2100mAh battery that will charge an iPhone 6/6 Plus up to 100%, or an iPhone 6s/6s Plus up to 75%. Four LED lights indicate the pack's power level, and a simple On/Off sliding power switch indicates if your unit is on or off. When it's time to recharge the PowerPack, just plug it into any USB port using the included charge cable. The PowerPack is less than a quarter inch thick, so it fits comfortably in the palm of your hand, and can be conveniently stowed away in your pocket or weekend duffle. At just 2.5 ounces, the PowerPack is lighter than your iPhone 6, so you'll hardly feel it's there.
