I had bought a power bank of mi 10000 mah last year through the mi india app.I few days it had worked but after that even not charging. In the charging process my MI max 2 charger got spoiled badly.
So, I have bought a new mobile charger and C port cable from mi also. now I cant recommend this one. I would say to you do not buy it. If you will buy one day you can face same problems.
