Do you need a travel adapter for Hong Kong?
It depends on where your plugs come from.
🇺🇸 From the United States
You need a plug adapter. Plugs from the United States (Type A and B) don't fit the Type G sockets in Hong Kong. A Type G (UK 3-pin) adapter fits the listed socket families there. Socket variants can differ; check the actual outlet and adapter rating.
Hong Kong uses 220 V, much higher than the 120 V in the United States. An input rating of "100–240V" covers the listed supply voltage; you still need a suitable plug or adapter. For single-voltage devices, follow the manufacturer's guidance on conversion; using a suitable local device may be simpler.

No plug adapter needed. Plugs from the United Kingdom (Type G) fit the Type G sockets in Hong Kong.
Hong Kong uses 220 V and the United Kingdom uses 230 V, but similar nominal voltages do not guarantee compatibility. Check that your device's input rating covers the destination supply.

Sockets you'll find in Hong Kong
Will your devices work in Hong Kong?
Sockets in Hong Kong supply 220 V. Find the "input" line on each device or its charger. An input rating of "100–240V" covers the listed supply voltage; you still need a suitable plug or adapter. Check that the input frequency also covers 50 Hz. An adapter changes the plug shape, not the voltage or frequency. For switchable devices, follow the manufacturer's instructions before plugging in.
Often rated 100–240 V; confirm on the charger: phone charger, laptop charger, camera battery charger.
Check the label first: electric toothbrush, electric shaver, CPAP machine, hair straightener / curler.
Usually single voltage: hair dryer, kettle / coffee maker, anything with a heating element.
