The Xiaomi 212W HyperCharge Power Bank 25000 features a single button that allows for intuitive control of various functions. When the screen is off, pressing the button lights up the display, showing the working interface. If the screen is on and functioning normally, pressing the button switches between different working interfaces. A double press activates the low-current discharging mode, and another double press exits this mode. For system restarts, pressing and holding the button for seven seconds reboots the device. If the screen displays an error alert, pressing the button returns it to the working interface, ensuring smooth operation at all times.
Note:
When the screen is in the full light status, if there is no interaction for 30 seconds, the screen will darken and then totally go out if there is no further interaction after 2 seconds.
