4000mAh Battery Charger Snap Case

Honestly, this is very good quality product. I never expect this has good shape with quality product with this price. Good stuff to have if your iPhone is easy to run out of battery.

This power bank charge high speed ,and easy carry ,like it

Fully integrated with my 6S, you can 100% fill your phone's battery, no need to carry a charger when you go out, it suits me!

Arrived faster than expected. Product as described.

I like this case ,it charges your phone from 20% to 100% one time，you can charge the case separately or charge it along with your phone it is made of rubber which makes the case feel smooth，there are negatives reviews but that happens with every product，you cant avoid the fact that some products come damaged sometimes but in my case the product worked and is still working，I feel I want to write this review because this battery case is cheaper than the version apple sells and does the same and it also has more positive reviews than apple‘s version，I dont want others to waste their money on more expensive smart battery cases when this delivers what you want
