Plug Adaptors

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

What type of plug does your appliance have?

Your Appliance has Plug Type A

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

Socket Type A
(Saudi Arabia) to Plug Type C
(Vietnam)

Socket Type A
(Saudi Arabia) to Plug Type G
(Vietnam)

Vietnam also uses Socket Type A, which is used in Saudi Arabia. If using an appliance that has a Type A Plug in the Type A Sockets of Vietnam, you will not need an adaptor.

Your Appliance has Plug Type B

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

Socket Type B
(Saudi Arabia) to Plug Type A
(Vietnam)

Socket Type B
(Saudi Arabia) to Plug Type C
(Vietnam)

Socket Type B
(Saudi Arabia) to Plug Type G
(Vietnam)

Your Appliance has Plug Type F

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

Socket Type F
(Saudi Arabia) to Plug Type A
(Vietnam)

Socket Type F
(Saudi Arabia) to Plug Type C
(Vietnam)

Socket Type F
(Saudi Arabia) to Plug Type G
(Vietnam)

Your Appliance has Plug Type G

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

Socket Type G
(Saudi Arabia) to Plug Type A
(Vietnam)

Socket Type G
(Saudi Arabia) to Plug Type C
(Vietnam)

Vietnam also uses Socket Type G, which is used in Saudi Arabia. If using an appliance that has a Type G Plug in the Type G Sockets of Vietnam, you will not need an adaptor.

Considerations

Voltage

The voltages found in Saudi Arabia (127V and 220V) are the same as those found in Vietnam. As there are multiple voltages present, care should be taken to ensure your appliance is compatible with the power outlet you are using.

Frequency of Electrical Current

The frequency of electrical current found in Saudi Arabia (60Hz) differs to that found in Vietnam (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.
