What kind of electrical adapters do I need for Hong Kong?

going for work next week so I'd like to buy whatever adapter I need this weekend. two prong 110VAC to what???

I believe they use 220V on the British plug (3pronged square), though you might be seeing some of the flat bladed 2prong since that's what China uses. Check your GBA, it very likely to be able to handle 100-240V so all you may need is a plug adapter.

pretty much the entire world uses 220v lol
