Is the voltage in Hong Kong the same as China's?

China is nominally 220 V/50 Hz; Hong Kong is 220 V/50 Hz. Wide-voltage chargers marked 100–240V work without a transformer.

Hong Kong plug types & voltage — adapters, 100–240V devices and local sockets

Hong Kong uses UK-style Type G three-pin sockets, usually switched, at 220 V/50 Hz.

Sockets & supply

GType G — three rectangular pins (BS 1363)

Voltage220 V

Frequency50 Hz

Legacy sockets still around: D/M type

UK-style Type G three-pin sockets at 220 V; mainland flat-pin plugs need an adapter.

From China — your plugs vs local sockets

two flat pins needs adapter Euro round pins needs adapter angled three-pin needs adapter

Adapter None of your plugs fit — an adapter is a must. Buy: an adapter to Type G, or a universal adapter.

Voltage 220 V → 220 V: close enough — no transformer needed.

Frequency 50 Hz → 50 Hz: nothing to worry about.

Coming from somewhere else?

On the ground

Hong Kong uses UK-style Type G three-pin sockets, usually switched, at 220 V/50 Hz.

Legacy British Type D/M outlets still appear in older buildings; hotels often provide USB ports or universal sockets, but bringing your own G adapter is safest.

What to pack

No Chinese plug fits — a Type G adapter is mandatory; no transformer needed at 220 V.

Type G is earthed and fused; buy a certified adapter with safety shutters.

Wide-voltage (INPUT 100–240V) chargers and power bricks work anywhere; single-voltage heating appliances (hairdryers, kettles) need a transformer when voltages differ. Country data cannot certify a device — check the nameplate.
