Top Travel Essentials to Take With You
Travelling light doesn’t mean travelling unprepared. A luggage scale gives you peace of mind at the airport, a power bank makes sure you’ve always got charge, and packing cubes keep your clothes neat and easy to find. Once you try them, you won’t go back.
Type G sockets have three rectangular pins arranged in a triangular pattern, with a built-in fuse for safety. They are the standard used in the United Kingdom.
Do You Need a Voltage Converter?
You don’t need to worry about a converter in Cardiff; the voltage is virtually identical to what we use in the UK.
Do check the voltage label on your kit before you travel. If it states ‘100–240 V, 50/60 Hz’, you’re safe to use it without a converter.
