According to these 3 sites:
1. https://www.techmesto.com/identify-fake-xiaomi-power-bank
2. http://en.miui.com/thread-*******-1-1.html
3. http://www.mi.com/verify/
The power bank that I received appears to be fake. Security code (******* - ******* - ******* - *******) was used 3347 times before which means that many units are sold with the same security code (security code allows you to check if you have an original or a fake unit).
USB ports are mounted incorrectly, the cable is not an original one.
It weighs 252g, the real one weighs 350g according to Xiaomi website.
I'm really disappointed.
