No adapter with you and already abroad? You’re not out of options—many airports and local shops sell them. Still, bringing your own is the easiest way to avoid overpaying or ending up with something that barely works.
Seria is commonly combined with destinations like Indonesia, Philippines, or Malaysia. Be sure to check outlet compatibility across your trip.
Do You Need a Voltage Converter?
If you’re traveling to Seria, you’ll probably need a voltage converter. The U.S. uses 120V, but the voltage in Seria is different, meaning your electronics won’t work safely without one.
Always check your device’s voltage rating before packing for an international trip. If the label says “100-240V, 50/60 Hz”, it can safely run on both 120V and 220-240V power sources without a converter. This applies to most laptops, tablets, smartphones, and electric razors.

More About Seria
Seria is a small town with a big role in Brunei’s economy—this is where oil was first discovered in 1929, and it’s still the heart of the country’s petroleum industry. You can even visit the Billionth Barrel Monument, which celebrates one of Brunei’s major milestones in oil production. The vibe here is industrial-meets-suburban, but it’s clean, green, and surrounded by long stretches of open road and coastline.
There’s not much in terms of tourist hustle, but you’ll find a few solid local cafés, open-air markets, and surprisingly well-maintained parks. Locals tend to know each other, and it’s not uncommon to see people waving to drivers from their porches. The Oil and Gas Discovery Centre is a great stop if you’re curious about how this quiet little town fuels the nation. It’s family-friendly and hands-on, especially if you’re traveling with kids.
Seria gives you a peek into Brunei’s working-class rhythm without losing that small-town friendliness. For American travelers, it’s an easy and interesting day trip from Bandar or Kuala Belait. If you’re into industrial history, local culture, or just want a quiet place to watch the sunset over the South China Sea, Seria ticks the box.
Seria uses the same plugs and outlets as the rest of Brunei.
