Charging with 2 power source at the same time

Hello! I just bought an external monitor (BenQ EW2880U). Its USB-C to USB-C cable charges my Macbook Air (15" 2023). This USB-C also provides me with the 4k / 60hz experience that I need. I do not want to use an HDMI cable.


I would like to know if it's safe to plug in my Apple 70W brick charger at the same time as the USB-C that charges from my BenQ monitor?


Thank you!!

MacBook Air 15″, macOS 14.1

Charge your MacBook Air or MacBook Pro - Apple Support


"Your Mac charges over only one port at a time, so connecting multiple power adapters to the USB-C ports and MagSafe 3 port (if present) won't charge your Mac faster …  If you connect more than one power source, your Mac charges only from the cable and power adapter or display providing the most power."

Yes.
