The table below summarises the plug types, voltage and frequency of electrical current in both Gambia and Tonga.
| Gambia | Tonga | |
|---|---|---|
| Plug Types | G | I |
| Voltage | 230V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Gambia uses Plug Type G.
You will need this adaptor:
Socket Type
(Gambia) to Plug Type I
(Tonga)
The voltages found in Gambia (230V) and Tonga (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Gambia and Tonga is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
