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

Heading from Indonesia to Brunei? Plug types and voltage standards differ between countries, so a little preparation goes a long way. Here's a breakdown of what to expect at the wall socket.

Your Indonesia plugs (Type C, F) won't fit Brunei's outlets (Type G). You'll want to grab a universal travel adapter or one specifically designed for Brunei before you depart.

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