iPhone 7 Plus / 8 Plus Battery Case, XchuangX 3600mAh Rechargeable Protective Charging Case Slim for Apple iPhone 7 Plus / 8 Plus (5.5 inch) Built-in 3.5 mm Headphone Jack, Support Sync-through (Black

This case has a good battery and aux port, but had HORRIBLE protection. I was happy with it until my phone fell out of my pocket when getting out of my car. The case cover poped right off on impact and my phone is now damaged.

Before I even bought my iphone 7plus I knew I wanted to get a battery case, and after looking online I couldn't find a case that had a battery and also the headphone jack but now since I've found this product and have used it for over a month I'm very satisfied with the build quality and compared to other battery cases, how slim it is.

Great product! The only drawback is that the lightning port only enables you to charge the phone, but not listening to music. Anyway, you still have the 3.5 jack which is why it's worth it! :D

Not a perfect fitAnd charger didn’t work

Meh. No phone on headphone jack and the case charging mode defaults to off vs on. Mophie is the only company I’ve found who has a battery case that defaults to on.

Terrible

Face frame cracks easily making case useless.

good
