The table below summarises the plug types, voltage and frequency of electrical current in both Benin and Cambodia.
|Plug Types||E||A, C, G|
|Frequency of electrical current||50Hz||50Hz|
Benin uses Plug Type E.
In Cambodia there's more than one socket type in use. You may require more than one adaptor.
The voltages found in Benin (220V) and Cambodia (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Benin and Cambodia is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
