The table below summarises the plug types, voltage and frequency of electrical current in both Tonga and Solomon Islands.
| Tonga | Solomon Islands | |
|---|---|---|
| Plug Types | I | G, I |
| Voltage | 240V | 220V |
| Frequency of electrical current | 50Hz | 50Hz |
Tonga uses Plug Type I.
In Solomon Islands there's more than one socket type in use.
You will need this adaptor:
Socket Type
(Tonga) to Plug Type G
(Solomon Islands)
Solomon Islands 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 Solomon Islands, you will not need an adaptor.
The voltages found in Tonga (240V) and Solomon Islands (220V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Tonga and Solomon Islands is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
