Summary

The table below summarises the plug types, voltage and frequency of electrical current in both Hong Kong and Philippines.

	Hong Kong	Philippines
Plug Types	G, D, M	A, B, C
Voltage	220V	220V
Frequency of electrical current	50Hz	60Hz

Plug Adaptors

In Hong Kong there's more than one plug type in use.

What type of plug does your appliance have?

• Type G
• Type D
• Type M

Considerations

Frequency of Electrical Current

The frequency of electrical current found in Hong Kong (50Hz) differs to that found in Philippines (60Hz).

Most equipment is not affected by differences in frequencies. Some exceptions are:

• Electric clocks: Some electric clocks use the frequency of electrical current to measure time. If the clock is designed for one frequency, but used with another, time shifts could be experienced.
• Appliances using motors: If there is a motor load associated with an appliance, the frequency governs the speed in revolutions of the motor. This could mean that the motor will spin faster, or slower than intended and could have a detrimental effect in the appliance's operation. This is of particular concern in power tools and other machinery that uses motors, so if you must use these, you should seek access to a frequency converter.

Good to know

Voltage

The voltage found in Hong Kong and Philippines is exactly the same (220V). You will not need a transformer.
