Is it normal that the four lights blink together when Mi 50w Power Bank 20000mAh is powering the device?

Solution:

It is normal that the four indicator lights blink together when the power bank is charging. When the power of the power bank is between 75% and 100%, the device is charged, and the four indicator lights blink together.

Note: it is an abnormal phenomenon that the four lights blink together when the power bank is charging itself. It is recommended to contact Xiaomi after-sales service.
