Kotech iPhone 6 6s Battery Case Ultra Slim Extended Charging Case External Battery Case Portable Charger for iPhone 6 6S 4.7 inch with 2400mAh(Rose Gold)

This case works great. I've bought several other charging cases and all of the previous ones stopped charging quickly. So far this case is doing a great job st charging my phone. I like that it's almost as slim as a normal case. And that I can plug my lightning charger directly into it - no new cords. The only complaint I have is I wish the sides came up a bit higher to creat a bit of a bumper to protect the screen, but I'm overall very satisfied.

I've bought two of these. The one for my phone works great and has for a year, the new one I bought a couple weeks ago for my wife's phone runs so hot it makes the iPhone 6 shut off. Worse, it only does it on occasion, not consistently. Returning that one, will update review if the problem goes away.EDIT: Problem went away with second battery case.

Great case just wish the battery lasted a lil more gets me through the day
