Mi Band supports maximum 25mA charging current, significantly lower than a common mobile phone. Normally this will cause the power bank to misinterpret as the Mi Band has already achieved full battery capacity and automatically cut off the charging current. BUT:
● some power banks support small current charging and can charge your device directly.
● if your powerbank is equipped with multiple USB output ports, you just need to use both of the USB ports: the first one will be working in normal condition and the other one will not cut off the charging current.
Use one port to charge your phone or insert a Xiaomi LED light, don't say it's not working.
