Power Plugs & Voltage in Hong Kong
In Hong Kong, the standard voltage is 220V at 50Hz, and plug type G is used.
Your Type A / Type B plugs don't fit Hong Kong's Type G sockets. Pack a plug adapter.
Hong Kong runs much higher than home. A single-voltage 120V appliance can be damaged — you'd need a voltage converter. Dual-voltage devices (100–240V) are still fine.
Check your charger Most phone, laptop and camera chargers are dual-voltage (look for “INPUT: 100–240V” on the label). Those only ever need a plug adapter, never a voltage converter. High-wattage items with heating elements (hair dryers, straighteners, kettles) are the usual exception.Hong Kong mains: 220V, 50 Hz.
Note Hong Kong uses the UK-style Type G plug (a legacy of British rule).

Many modern chargers, laptops, phones and cameras are dual-voltage: their label reads INPUT: 100–240V. Those work anywhere in the world with just a plug adapter — no voltage converter needed. Only single-voltage, high-wattage devices (hair dryers, travel kettles, straighteners) are a real concern in Hong Kong’s 220V supply. Always check the label on your own device.

Frequently asked questions
What plug type is used in Hong Kong?
Hong Kong uses Type G plug. Hong Kong uses the UK-style Type G plug (a legacy of British rule).
What voltage is Hong Kong?
The standard mains voltage in Hong Kong is 220V at 50Hz. Most modern chargers and laptops are dual-voltage (100–240V) and work fine; single-voltage appliances from a country with very different voltage may need a converter.
Do I need an adapter for Hong Kong from the US?
Yes. US plugs (Type A/B) don't fit Hong Kong's Type G sockets, so you'll need a plug adapter. The US is 120V and Hong Kong is 220V, so single-voltage US appliances may also need a voltage converter. Use the checker above for your exact home country.
Do I need an adapter for Hong Kong from the UK?
Hong Kong uses the same UK-style Type G plug, so no adapter is needed, and the voltage (220V) matches the UK's 230V.
