Travel adapter from Brazil to Brunei
Adapter Required
Yes — coming from Brazil, you will need a travel adapter for Brunei. Brazil uses Type C/Type N plugs, and Brunei uses Type G, so the pin shapes will not fit any wall socket. The mains frequency is also different (60 Hz vs 50 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
