Just found that there are 2 more 32A Tesla charging sites in Tesla webpage: One for public: Royal View Hotel in Ting Kau (Weekdays: $250 for 2 hours free, $350 for 3 hours free, $28 per hour; Weekend: $350 for 2 hours free, $450 for 3 hours free, $40 per hour). One for members only: Clear Water Bay Golf and Country Club. Hope it helps.
Oh didn't realise Royal View Hotel now has it. Was there some months ago and it had nothing. Glad they have it now as I live nearby. The car park entrance is damn narrow though, I think I almost had to retract my side mirrors to squeeze in/out haha
