I bought this power bank from Amazon. It has 10000 mah Battery. It has 2 output one is 5 V and 2 A and second is 5 V and 1 A. And personally I am not satisfied with this Because I think both output will be higher. And also there is not any indicator which tell you that which is the 2A output and 1A. So I think this is not a good thing. Last but not least this power bank has not fast changing support and it takes to much time for the charging.
It has four light indicator which tell you that how much charging remaining in the power bank.
It also supports pass to charging. Which most of the power bank not support in this price segment. I think this a good feature.
I you can buy this this is a good product.
