“If your Mac has USB-C ports, you can charge your Mac with a USB-C charge cable and a USB-C power adapter or with a USB-C or Thunderbolt display that provides power. Your Mac can charge 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 result in faster charging. If you connect more than one power source, your Mac will only charge from the adapter or display providing the most power”
