I attempted with Korgou – All for your Korean shopping but my CC company and the bank each had fraud alerts and rejected the payment.Sounds like package-forwarding service is the way to go?
I also had issues figuring out what should go in the 3 boxes Address 1, Address 2 and City as Tesla didn't seem to ever validate the address.
2F, 79, Sunhwan-ro, Jungwon-gu, Seongnam-si, Gyeonggi-do, Republic of Korea
Issue #1 is easy enough to fix but due to the address issue, it gave me enough pause to think I was on the wrong track.
Ha, ha. Yes. Tesla will probably "catch on" and may stop orders from North American Tesla owners, possibly. Get your CCS1 adapters while you can! (Just kidding. I am not encouraging anyone to take the risk.)
However, I would probably order one for myself, because I like "breaking the rules," but I am pretty sure (from looking at photos) that the South Korea CCS1 adapter is PHYSICALLY INCOMPATIBLE with the Models S & X charge port. I would love to hear confirmation from anyone in North America (or from South Korea, for that matter) as to whether this is actually true. But it looks to me like the open charge-port cover-door would interfere with the adapter and that the adapter's locking pin might rub the car's paint near the port. I suspect that a different adapter design is going to be necessary for the Models S & X, unfortunately.
Take a look at the photos. The Models 3 and Y port area has a relatively large expanse of black plastic around the port itself. Not so on the Models S and X. The Models 3 and Y cover-door opens up out of the way. But the open door is right next to and in the way on the Models S and X.
If you want to bring one into the country I could be your backup plan. If it works for you keep it. If it doesn't work I would be glad to pay you for the adapter, your shipping, and shipping it to me.
