Hi guys, today I am going to tell you all that how we get cheated by any company products. Today I am going to tell you my experience.
I purchased billion power bank 15000 mah for charging my phone mi a2. My phone has 3000 mah battery. When I purchased it, it works great. But after few days it did not charge my phone quickly. It tooks 3hrs to charge my phone 100% .
This is also not a big issue, but then after few days power bank automatically becomes storage of 4000mah. Means it converts from 15000 to 4000 mah automatically. This is what happened with me. So please do not buy this product. Must cheak before buying any product. Thank you.
