Review on 5000MAh Battery Case For IPhone 11 Pro Max - Ultra Slim Portable Protective Charging Case Extended Rechargeable (6.5 Inch) Black by Pradeep Dhimal

【Advanced Sync Technology】This iPhone 11 pro max charging case and your iPhone 11 Pro max can be charged at same time when you use your original charging cable.Bought this case for a friend because he travels a lot and hates carrying multiple chargers/cords with him. I bought this case specifically because the description states the case and the phone can be charged at the SAME time. Maybe I received a defective one, but i tried working it out with the seller who confirmed they would send a replacement case, and didn't. I contacted them 2x via email, with no reply.Both the case and the phone can be charged if there is still life on the CASE, but once the case is completely DEAD, 0% battery life, the phone will not charge when it is plugged into your lighting cable.
