It is a worst quality power bank. That is like a simple power bank in this high reang. I am useing this power bank for only 2 months.yet I am see many problems in this power bank. Though it have 10000 mAh bettry but this power bank not supply 10000 mAh charge. You can buy other 10000 mAh power bank in this reang. The cost of power bank 3500₹. It is maked with black cooler.
