Battery Case for iPhone 11 Pro Max,Upgraded 10000mAh High Capacity Rechargeable Portable Protective Extended Charger Case Compatible with iPhone 11 Pro Max (6.5 inch) Charging Case & Carplay (Black)

Quality and price as well as performance is great! Highly recommended.

My husband is using this for his older iphone that is not staying charged anymore. Once the main battery is down low he presses the product button and it recharges his phone quickly. For the price he thinks it is great. I would recommend. He has only had it for a couple months, so only time will tell.

The headline says it all. The major clue is that it's a fraction of the weight compared to the other 10000mAh battery cases.Why three stars? Unlike the other Chinese battery cases, this one has yet to burst into flames, melt, or stop working. Then again, I've only had it for two days.Case is a bit slippery too. But it is easier to hold (being significantly lighter than a *real* 10000mAh battery case).

Worked a couple times and then I could not get it to charge my iPhone 11 Pro Max. Case charges but no matter how many times I try it will not charge my phone. Tried other phones to see if it was my phone and it failed to charge them too.

Stopped taking a charge after 4 weeks . Looks pretty cool

Just today this item stopped charging my phone… the device is still charged but it no longer passes the charge to the phone….. not sure why? I wanted to return it however as it goes a day late and 40$ short

I had a different case that more than doubled the life of my battery. This one adds absolutely no additional lifespan. Do t know if it’s broken or just poorly made, but it does not work.

First one lasted about 6months. Second one didn’t work after two weeks. Don’t waste your money
