Do You Need a Voltage Converter?
In Portsmouth, the power supply operates on a different voltage than the U.S. standard of 120V, so a voltage converter is likely required for your devices to work properly.
Always check your device’s power label before traveling. If it says “100-240V, 50/60 Hz”, your device can handle different voltages worldwide without needing a converter. This applies to most laptops, tablets, cameras, phones, and rechargeable personal care devices.

More About Portsmouth
Portsmouth is Dominica’s second-largest town, but it has a relaxed, small-town feel that’s perfect if you’re looking to escape the crowds. It’s tucked into a natural bay and surrounded by green hills, giving it a peaceful vibe with plenty of access to nature. The town sits right next to Cabrits National Park, where you can hike through tropical forest and explore old military ruins with sweeping views of the coastline.
This is the kind of place where you can kayak down calm rivers one day and snorkel over coral reefs the next. Locals are friendly, things move at a chill pace, and you’ll find a handful of cozy guesthouses and beach bars serving fresh fish and cold drinks. There’s a raw charm to Portsmouth—less polished than the capital, but rich in character.
If you want a more off-the-beaten-path side of Dominica, Portsmouth delivers. It’s got history, access to outdoor adventure, and that no-fuss, barefoot feeling that makes Caribbean travel so rewarding. No need to rush here—just let the island set the rhythm.
Portsmouth uses the same plugs and outlets as the rest of Dominica.
