Hong Kong Home Appliances
The domestic power supply in Hong Kong is based on the UK-standard of 220V-240V on 50Hz with a G-type plug/socket, as illustrated. You can check here to see if appliances in your country will be compatible with Hong Kong home appliances.
It is important to note that for Hong Kong home appliances:
- Hertz cannot be changed by a transformer, so 60 hertz home appliances (such as some domestic US appliances) cannot be used in Hong Kong.
- Voltages can be changed using a transformer, which you can buy on Amazon or from some electrical retailers.
- You can buy G-type plugs when you get to Hong Kong. These should only connected to your Hong Kong home appliances or transformers that are suitable for 50 Hz and 220V-240V.
Buy Transformers for Hong Kong Home Appliances
On the back of your appliance, you will find a label describing the power requirements. You should see a label describing the Wattage (W) or the Amperage (A) of the appliance. If you only know the Amperage, you can calculate the Wattage:
For example a 3 Amp device x 110 volt (US) requires a (3×110) 330 Watt Transformer with +10% minimum. You should exceed this by at least a further 20% if your appliance runs a motor. In that case you would require a 430W transformer.
Choose a voltage transformer / converter which can handle a higher amount of wattage then your device is rated at. Certain devices which are motor based may require additional power to start up then indicated (know as Surge), in this case always add an extra 20% to the power requirements of your device. By using a surge-protected extension you can connect more than one appliance to a single Transformer, as long as you don’t exceed the Wattage capacity of the voltage converter.
Hong Kong Home Appliances – Your TV
In addition to the above, televisions have their own standard according to their location. These are:
- NTSC – National Television Standards Committee. Developed in the US and first used in 1954, NTSC is the oldest existing broadcast standard. It consists of 525 horizontal lines of display and 60 vertical lines. Only one type exists, known as NTSC M.
- SECAM – Système Électronique pour Couleur avec Mèmoire. Developed in France and first used in 1967. It uses a 625-line vertical, 50-line horizontal display. Different types use different video bandwidth and audio carrier specifications. Types B and D are usually used for VHF. Types G, H, and K are used for UHF. Types I, N, M, K1 and L are used for both VHF and UHF. These different types are generally not compatible with one another.
- PAL – Phase Alternating Line. Developed in Germany and first used in 1967. A variant of NTSC, PAL uses a 625/50-line display. Different types use different video bandwidth and audio carrier specifications. Common types are B, G, and H. Less common types include D, I, K, N, and M. These different types are generally not compatible with one another.
Hong Kong’s TV standard is PAL1, as in the UK. Even if your country uses another standard, your TV may be multi-standard so check the user guide carefully.
