I wonder about the plug jack style fitting.
That's a good point, but I think
all PSU's use a C14 connector with a C13 type power cord with different ends to plug into the mains, depending on locality. You won't get a cord compatible with Hong Kong sockets when you buy it here in the US, but I'm sure you can get one in Hong Kong.
If I'm wrong in any of that, someone please feel free to correct me.
