Type G is standard; the round-pin Type D and M sockets are legacy fittings.

Arriving from the United States or CanadaA plug adapter, and appliances marked 100-240 V. Anything single-voltage needs a converter.
Arriving from the UK or IrelandPlugs go straight in and the voltage matches. Nothing to pack.
Arriving from most of continental EuropeA plug adapter is enough - the voltage is the same as at home.
Arriving from Australia or New ZealandA plug adapter is enough - the voltage is the same as at home.

Socket types, voltage and frequency are the nominal domestic supply as published in IEC/TR 60083 and the national standards it lists.

Hong Kong uses British Type sockets at 220 V, with round-pin legacy outlets surviving in old buildings.

Sockets in Hong Kong are Type at 220 V, 50 Hz - the British three-pin plug, a legacy of the colonial wiring standard.

British plugs fit straight in. Everyone else needs an adapter, including travellers from mainland China.
Round-pin Type and sockets survive in older buildings and on some fixed appliances; they are not something you need to plug into.
220 V rather than the UK's 230 V makes no practical difference - both sit inside the tolerance every appliance is built for.
Adapters are sold everywhere in Sham Shui Po and any convenience store, usually cheaper than at the airport.
