Don't they use the same IEC 62196 ports as other EVs, outside the US?

They made their own in the US, because the standard SAE J1772 combo port is an unweildy behemoth, then they released the patent into public domain, and the rest of the automotive industry adopted their port into the NACS port, which beats both IEC 62196 and SAE J1772 in available power, all in a much smaller and easier-to-use connector.
