Your car should come with a couple of adapters. My Model Y came with a j1772 adapter, which has worked well with most level 2 chargers. It also came with an adapter that allowed me to plug into an extension cord at my brother-in-law's house last weekend. It was very slow, but it worked. I had to set the amps down to 20 to make it work. I'm still trying to learn...apparently CCS-1 is the up-and-coming standard for non-Tesla EV fast charging in the US, but maybe Model 3 and Y can't use it for fast charging, and the adapters are expensive. I have seen in some of these forums where Tesla is supposed to be "offering one soon," whatever that means. I don't know a lot about Chademo. I live in a condo building, so I can't entertain putting in a 220V home system, but we have a ChargePoint Level 2 station in our complex, and a Tesla SuperCharger station a couple of miles away. We took our first road trip (260 miles) last weekend, to western Pennsylvania from Virginia. It was a little hairy, but now that I know the charging landscape in that area, I can do better next time. Had I had the capacity for CCS-1 fast charging, it would have been easier, because there was a Sheetz station with 4 CCS-1 chargers near where we were staying; the closest Supercharger was 30 miles away (in the wrong direction). It made my wife very nervous watching the charge decrease when we were far from the station, because it's not like you can get AAA to come out with a can of volts to get you to the next charging station if you run out. Having said that, though, had I planned a bit better we would never have gotten low.
