I think your link got cut-off. Correct link is:
Model S Chargeport Opener - Stegen Electronics
These work perfectly on Hong Kong Model S. They not only open your car's charge port, but also any other Model S charge ports in the vicinity! The guy behind them is a 'hacker' in the true sense of the word. Highly recommended.
Thanks Mark!
I have updated the product page and added Asia as supported area.
