I got my Model Y in mid-2021, so it came with a mobile connector. I'm considering installing a NEMA 14-50 outlet at my home, but I couldn't find the NEMA 14-50 adapter for the mobile connector. I recall when I opened the bag there were 2 adapters and I have been using the 120v one for 2 years. Did it come with 2 adapters or just one?
