Which plug adaptor do I need when travelling from Eritrea to Antigua?

Summary

The table below summarises the plug types, voltage and frequency of electrical current in both Eritrea and Antigua.

	Eritrea	Antigua
Plug Types	C	A, B
Voltage	230V	230V
Frequency of electrical current	50Hz	60Hz

Eritrea uses Plug Type C.

In Antigua there's more than one socket type in use. You may require more than one adaptor.

Socket Type C
(Eritrea) to Plug Type A
(Antigua)

Socket Type C
(Eritrea) to Plug Type B
(Antigua)

The frequency of electrical current found in Eritrea (50Hz) differs to that found in Antigua (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.

The voltage found in Eritrea and Antigua is exactly the same (230V). You will not need a transformer.
