MI power Bank 2i 20000 ah battery is not really awesome I have purchased this with online marketing and I am not happy with this power Bank I always remember last time I have purchase another power Bank and it was on the 10000 MH off battery life that one is awesome more then this power Bank. I will not say the name of my previous power Bank but I'll just say a if you have not a 4000 5000 mah battery life of of your Android device so please purchase anyway but your Android device is more than 4000 MH battery life so please do not purchase this is my personal experience.
and all those user who has not more than 3000 battery of life so please this product made for you only thank you
