The table below summarises the plug types, voltage and frequency of electrical current in both Nauru and Macau.
| Nauru | Macau | |
|---|---|---|
| Plug Types | I | D, M, G, F |
| Voltage | 240V | 220V |
| Frequency of electrical current | 50Hz | 50Hz |
Nauru uses Plug Type I.
In Macau there's more than one socket type in use. You may require more than one adaptor.

The voltages found in Nauru (240V) and Macau (220V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Nauru and Macau is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
