Mobile phone (via USB-C)
If there is no external power supply connected to the secondary USB-C port, the mobile
phone battery will supply power to the display. The mobile phone's USB-C output must be
larger than 5V 1A to provide power without external power. To reduce power usage, the
energy-saving mode will be activated and the display brightness will be automatically set
low. You can adjust the brightness and volume of the monitor according to the output power
of the mobile phone.
When connected to an external power supply through the secondary USB-C port, the
display will provide power to the mobile phone through the external power supply. The
brightness of the monitor will automatically adjusted when connecting with external power.
Note:
If using a power bank (not supplied) as an external power source, it must be larger than
18W. Power banks can be used as external power for every connection shown here, not
just mobile phones.
