| Eswantini (Swaziland) | Nigeria | |
|---|---|---|
| Plug Types | M | D, G |
| Voltage | 230V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Eswantini (Swaziland) uses Plug Type M.
In Nigeria there's more than one socket type in use. You may require more than one adaptor.
Socket Type M
(Eswantini (Swaziland)) to Plug Type D
(Nigeria)
Socket Type M
(Eswantini (Swaziland)) to Plug Type G
(Nigeria)
The voltages found in Eswantini (Swaziland) (230V) and Nigeria (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Eswantini (Swaziland) and Nigeria is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
