Sockets in Guam
In Guam, you’ll find Type A and B plugs and sockets.
Type A
Type A sockets have two flat parallel pins and no grounding. Unlike Type G, they don’t include an earth pin, which makes them less secure.
Type B
Type B sockets have two flat parallel pins plus a round grounding pin. Unlike Type G, the pins are thinner and there’s no built-in fuse.
Recommended Travel Adaptor for Guam
Many adaptors didn’t pass our tests, but this one did. We looked at safety, durability and value for money. That’s why we confidently recommend it.
Abroad with no adaptor? You’ll find some for sale at airports and in town. Just bear in mind they’re often overpriced and not the best quality.
Guam is often paired with stops in Japan and the Philippines. Good idea to check those pages too — plugs and voltage might be different.
Do You Need a Voltage Converter?
You might run into problems plugging straight in Guatemala, as the voltage isn’t the same as the UK’s 230 V. A converter will sort that.
Before using your device overseas, check the small print on the voltage label. Anything marked ‘100–240 V, 50/60 Hz’ will run without a converter, which covers most modern electronics.
Top Travel Essentials to Take With You
A few smart extras can make travelling so much easier. A digital luggage scale saves you from nasty surprises at the airport, a power bank keeps your phone alive when you need it most, and packing cubes stop your suitcase turning into chaos. We’ve tried and tested them ourselves, and they really do make a difference.
