Power Outlets in Cardiff
In Cardiff, they use Type G power plugs and outlets.
Type G

Type G outlets have three rectangular prongs in a triangular layout and built-in fuses. Other plug types won’t fit without an adapter.
Do You Need a Voltage Converter?
You’ll probably need a voltage converter in Cardiff since your device’s voltage has to match the local power supply. In the U.S., we use 120V, but Cardiff operates on a different voltage, so a converter is required.
Before packing your electronics for a trip, always check the voltage label. If it says “100-240V, 50/60 Hz”, your device is compatible with different voltage systems and doesn’t need a converter. This applies to phones, tablets, laptops, cameras, and rechargeable toothbrushes.

More About Cardiff
Cardiff, the capital of Wales, is a compact city brimming with style and substance. The waterfront at Cardiff Bay mixes futuristic architecture with sailboats and seafood cafés that feel vibrant without the London chaos. Castle Street leads you to Cardiff Castle’s 12th-century walls, sitting right in the middle of town, with tunnels and towers to explore. Nearby, stylish neighborhoods and old-school shopping arcades blend modern buzz with Welsh history.
Some fun surprises: Cardiff hosted the first Welsh-language TV broadcast and is full of live music venues and food halls with everything from Indian street food to traditional Welsh dishes like lamb cawl. The Principality Stadium often hosts rugby matches where fans—locals and visitors alike—belt out national anthems and cheer with unmatched energy. Green spaces like Bute Park stretch for about 130 acres, offering shady spots for a picnic or a break from city buzz.
For Americans, Cardiff is an easy, English-speaking entry into Welsh culture. You can get around the city quickly via bus or on foot, explore free museums, and enjoy cozy pubs with local ales and plenty of storytelling. It’s a friendly, walkable city that mixes old-world charm with modern culture—and it’s a great base if you plan to explore the rest of southern Wales.
Cardiff uses the same plugs and outlets as the rest of Wales.
