YISHDA Galaxy S9 Charging Case 4700mAh Rechargeable External Battery Charger Case for Samsung Galaxy S9 Slim Extended Backup Power Bank Case | Samsung Galaxy S9 Portable Battery Case - [5.8inch] Black

This is very handy for everyday use as it, yes it's a bit big and bulky but it fits perfectly in your pocket and in your hand. I would definitely recommend this to anyone who is always on the go and isn't able to get to a charger.

Works well and fits flush. Charges S9 quickly from complete dead.

I used it for two days and it was not working as it was suppose to. The charge indicator was not indicating properly. AFter charging for less then 10 minutes, the LED would turn form 'white' (it was more like baby blue or a maya blue) to green. Then, another 10 minutes later, it would turn into blue and it stayed there for a while. It managed to charge my S9 one time and about 9% more after, however I did use it for about 30 mins while it was charging before the battery case died. I have used phone with 4500mAh battery and it lasted a whole lot longer than my S9 with this battery case.This is the first time using a prodict form YISHDA brand and the experience was not good. The built quality and the material used was good and it felt good to hold even though it was very chunky but it is normal for battery cases like this.In conclusion, I would not recommend it. Also, if you read some of the other reviews it is clear not for this product and it was written for different but similar product. Doing this will make their product look like they got good rating even though it is bad.

Just had it to day and it's broken put my phone in and it's not working it went in the bin within 10mines
