I would occasionally get into the loop of charge/not charge with an OEM 200W charger Random shutdown and the development version of sysctl firmware that has PD improvements resolves the problem with this charger. Note that while the charger has technically a number of ports and high output power only two of the USB C ports can be used reliably. When 3 ports are used the charger firmware starts to struggle with allocating power between the ports, and a reconfiguration loop can happen on the charger side.
