Sierra Leone to Brunei: Complete Plug & Adapter Guide (2026) Adapter Needed

Getting ready for your journey from Sierra Leone 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.

Since Sierra Leone and Brunei both support Type G plugs, you can use your chargers and appliances without a travel adapter. One less thing to worry about.

The voltage and frequency in Brunei (230V, 50Hz) are the same as Sierra Leone (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.
