Review on IPhone X XS 10 Battery Case - Slim Protective Charger With 4100MAh Rechargeable Power For Improved Phone Longevity And Performance, Compatible With 5.8 Inch Screen Size, In Black (New Version) by Jonah Riggle

This portable charging case is really good! It came in with very easy instructions on how to use it. The case itself is very smooth and not too bulky. What I like the most is that you can use your iPhone charger to charge the case, so there's no need for extra cables! I use it on my iPhone X and it fits very well! If you charge your phone up to 95% and put that charging case on and turn it on, it will keep your phone battery charged up until the case batter runs out, which is useful if you're constantly on your phone. Overall, very good!
