The table below summarises the plug types, voltage and frequency of electrical current in both Benin and Eswantini (Swaziland).
| Benin | Eswantini (Swaziland) | |
|---|---|---|
| Plug Types | E | M |
| Voltage | 220V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Benin uses Plug Type E.
You will need this adaptor:
Socket Type
(Benin) to Plug Type M
(Eswantini (Swaziland))
The voltages found in Benin (220V) and Eswantini (Swaziland) (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Benin and Eswantini (Swaziland) is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
