Sao Tome and Principe to Brunei: Complete Plug & Adapter Guide (2026) Adapter Needed

Getting ready for your journey from Sao Tome and Principe to Brunei? Electrical compatibility is easy to overlook, but bringing the wrong plug or forgetting an adapter can leave you scrambling at your hotel. Here's what you need to know.

Sao Tome and Principe uses Type C and F 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 the same as Sao Tome and Principe (230V, 50Hz), so your appliances should work without a converter.

A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Brunei specifically, look for one that supports Type G outlets. USB charging ports built into the adapter are a nice bonus.
