Galaxy S6 Battery Case by SQdeal Power Case

Galaxy S6 Battery Case, SQdeal 

I do not recommend this product at all.
Followed the instructions on charging.
When I first got it, seemed to work ok.
As long as my phone was in standby
mode it would charge,

If I was using the phone at all the
battery % would go down.
I bought it because the seller said "Yes, I will charge your phone while playing Pokemon Go."
By the 3rd time I tried to use it the power case
would not even charge the phone while it was
in stand-by mode. 
Won't even charge the phone when it's completely off.

I did get a 70% refund from SQdeal.
It took a while though to even get that.
