Which plug adaptor do I need when travelling from Pakistan to Guinea-Bissau?

Summary

The table below summarises the plug types, voltage and frequency of electrical current in both Pakistan and Guinea-Bissau.

	Pakistan	Guinea-Bissau
Plug Types	C, D	C
Voltage	220V	220V
Frequency of electrical current	60Hz	50Hz

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

What type of plug does your appliance have?

No adaptor needed

Guinea-Bissau uses Socket Type C, which is the same as the plug type of your appliances from Pakistan. You will not need an adaptor.

You will need this adaptor:

Socket Type
(Pakistan) to Plug Type C
(Guinea-Bissau)

The frequency of electrical current found in Pakistan (60Hz) differs to that found in Guinea-Bissau (50Hz).

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.

The voltage found in Pakistan and Guinea-Bissau is exactly the same (220V). You will not need a transformer.
