Mivi power bank 10000 mAh is not a good quality power bank. But this power bank is very beautiful. I am useing this power bank for 3 months. I know everything on this power bank. This power bank have many bad side. Those is slow charging of any phone, slow recharge, big size. It’s capacity is 10000 mAh but the power bank not supply 10000 mAh charge. This power bank waight is 350gm. So you not carry this power bank in your small bag. I suggest that you not buy this power bank because you not get a better bettry life. It cost only 800₹.
