There are multiple types of USB C cables/devices. Raspberry Pi advertizes itself as the wrong kind of device, so it will only get power from a cable/charger that ignores that information.

It's more subtle than that: the RPi4 will advertise itself as the wrong kind of device only when the cable advertises itself as a marked cable.
