Hong Kong - Traveller Notes
Largely based on UK system. Occasionally, a "shaver" socket (similar to Type C) is found in some bathrooms that provides low current to some other plug types. These almost always have a 110 V socket and a 220 V socket in the same unit, or a switch to select voltage, which are sometimes labeled as 110 V and 220 V. This duo installation is not as common in HK as in the UK. There was a smaller 2A version of type D, now obsolete.
Voltage Converters
Please be aware that whilst a power adaptor will allow you to physically insert a UK plug into a Chinese socket it will not change the voltage or frequency of the local mains supply.
Voltage - The Chinese mains supply is 220 V, which is within the normal UK range of 230 V +10%/-6%, so British appliances are compatible.
Frequency - Hong Kong operates at 50 Hz, the same as the UK. Frequency compatibility is therefore not a problem for UK appliances.
Most modern travel gadgets, chargers and laptops are dual voltage and will work worldwide; check the appliance or power supply for an input such as 100-240 V, 50/60 Hz.
If you have equipment that is not compatible with the Chinese supply voltage, check our transformers page for further information and available options for transformers and power converters that you can use in Hong Kong. Voltage converters and transformers only change the voltage, not the frequency, of the supply. Changing the frequency requires specialist frequency-conversion equipment, which is not normally practical for travellers.
If you need to take items like hair dryers / straighteners that draw high current then see our hair straighteners page for information on how it can affect your choice of travel adaptor.
Hong Kong Plug Type Specifications
Plug Type G
Type G plugs have 3 rectangular pins in a triangular configuration, and are rated at 13A. The live and neutral pins are 4mm x 6.35mm, 17.7mm long and spaced 22.2mm apart. The earth pin is 4mm x 8mm, 22.7mm long and offset by 22.2mm.
The live and neutral pins are insulated and the plugs individually fused. The sockets have safety shutters preventing access to the live and neutral until they are opened by the insertion of the (longer) earth pin. This makes type G plugs one of the safest designs in the world.
