Guinea-Bissau to Brunei: Complete Plug & Adapter Guide (2026) Adapter Needed

If you're heading to Brunei from Guinea-Bissau, it's worth checking the power situation before you pack. Different countries use different outlet types and electrical standards, so your devices may not plug in directly when you arrive.

Guinea-Bissau uses Type C plugs, while Brunei uses Type G. Since there is no overlap, you will need a travel adapter to plug in your devices. Make sure to pick one up before your trip or at the airport.

The voltage and frequency in Brunei (230V, 50Hz) are close to Guinea-Bissau (220V, 50Hz), so your appliances should work without a converter.

Don't forget that Brunei hotel rooms sometimes have a universal shaver socket in the bathroom, but these low-wattage outlets aren't suitable for high-draw devices. For reliable charging, use the standard wall outlets with a proper adapter.
