So, you’ll definitely need a travel adaptor in Mexico. Their plugs and sockets aren’t the same as our Type G back in the UK.

Sockets in Mexico
The plug types you’ll find in Mexico are 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.

Forgotten your adaptor and already abroad? Don’t worry — airports and local shops usually stock them. That said, packing your own saves you from high prices and poor quality.
Mexico is usually combined with travel to the United States and Guatemala. Worth checking the plug info for those countries — not everything is the same.
Do You Need a Voltage Converter?
The mains in Mexico doesn’t line up with the UK’s 230 V, meaning a voltage converter will be needed for some devices.
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.
