Otterbox has a resurgence Power Case for the Iphone. Anything similar for S5 Active?
I surfed and found many variations and different names for this concept. My phone and otterbox are great, but I struggle with low battery. By the afternoon I need to use an external power supply which is a huge inconvenience. Any solution that would give me extra power and give the same "otterbox" protection?

I just carry a 7,500mAh power bank with me if I think I'll need more power on the go. Fits in a jeans pocket. No Otterbox case like that for my phone either.
