The table below summarises the plug types, voltage and frequency of electrical current in both Eswantini (Swaziland) and Papua New Guinea.
| Eswantini (Swaziland) | Papua New Guinea | |
|---|---|---|
| Plug Types | M | I |
| Voltage | 230V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Eswantini (Swaziland) uses Plug Type M.
You will need this adaptor:
Socket Type
(Eswantini (Swaziland)) to Plug Type I
(Papua New Guinea)
The voltages found in Eswantini (Swaziland) (230V) and Papua New Guinea (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 Papua New Guinea is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
