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