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

Uruguay also uses Socket Type I, which is used in Tonga. If using an appliance that has a Type I Plug in the Type I Sockets of Uruguay, you will not need an adaptor.
The voltages found in Tonga (240V) and Uruguay (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Tonga and Uruguay is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
