Review on 4100MAh Slim Rechargeable Battery Case For IPhone X XS 10 - Black, Protective Charger Case Compatible With 5.8 Inch IPhone X XS [New Version] by Serguei Mracek

I was shocked when i received this one in the mail. I was amazed that it used NFC to charge, rather than using the lighting port. While i like this one more than the previous model. It is lighter and leaves open the lighting port for other accessories, the battery only fully charged my iPhone once. I carried it around for a week and i will say this, while it is lighter it was heavier than my normal everyday case so that took some getting use to, but for a case that i need when i can't charge my phone in the wall, this is the case i will be using!
