The table below summarises the plug types, voltage and frequency of electrical current in both Benin and France.
|Frequency of electrical current||50Hz||50Hz|
Benin uses Plug Type E.
No adaptor needed
France uses Socket Type E, which is the same as the plug type of your appliances from Benin. You will not need an adaptor.
The voltages found in Benin (220V) and France (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Benin and France is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
