No adapter in your bag? That’s okay—you can likely grab one after you land. But if you want to avoid the last-minute scramble next time, it’s worth getting one before you leave.
Swansea travelers often also explore Ireland or Scotland. Check if your plug works in each place.
Do You Need a Voltage Converter?
A voltage converter is likely needed in Swansea because your device must match the country’s voltage. The U.S. runs on 120V, but Swansea uses a different voltage, so a converter is necessary.
Before plugging in your devices abroad, always confirm the power rating on the label. If it lists “100-240V, 50/60 Hz”, your device is designed for worldwide use and won’t require a converter. Many modern gadgets, including laptops, tablets, and cameras, are built this way.
