The table below summarises the plug types, voltage and frequency of electrical current in both Nauru and Portugal.
| Nauru | Portugal | |
|---|---|---|
| Plug Types | I | C, F |
| Voltage | 240V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Nauru uses Plug Type I.
In Portugal there's more than one socket type in use. You may require more than one adaptor.

The voltages found in Nauru (240V) and Portugal (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Nauru and Portugal is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
