The ThinkPad P1 has no official requirements for USB-C chargers. This is the result of testing a few different USB-C chargers on my Gen 4 P1.
Notes:
- Machine BIOS is
N40ET44W 1.26. - This configuration (i7 11850H, RTX A3000) shipped with a 230W AC charger.
- Result wattage read from Lenovo Vantage on Windows 11 Pro.
- Windows does not acknowledge unsupported chargers at all (eg does not show any error messages). A KDE desktop does show a message that the wattage is too low for unsupported chargers.
- Tested with a 100W C-C cable or 100W TB4 cable.
