The table below summarises the plug types, voltage and frequency of electrical current in both Singapore and Brunei.
| Singapore | Brunei | |
|---|---|---|
| Plug Types | G | G |
| Voltage | 230V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Singapore uses Plug Type G.
No adaptor needed
Brunei uses Socket Type G, which is the same as the plug type of your appliances from Singapore. You will not need an adaptor.
The voltages found in Singapore (230V) and Brunei (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Singapore and Brunei is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
