I bought this powerbank in 2018 and was happy that mi was providing such good specifications at this cheaper price.But after some time I really got to know that why this powerbank has less price than the others.This power bank comes with the metalic body which heats very much when I use it.The charging speed of this power bank is also very slow and it took upto 8-9 hours to fully charge on the other hand other power bank takes 5-6hours only.Mi powerbank is very scra5ch friendly it got scrathes very easily.However I didn’t use it too much but it got many scratches.Sometimes I even charge it full but then after 1 or 2 days without use it shows me low battery.I had tried many power banks but doesnt face these types of problems with them.Mi should focus on their services to male it more user friendly.
