Mexico Plugs, outlets & travel adapters
Mexico uses Type A and B sockets. The mains supply is 127 V at 60 Hz.
Plugbert's take American-style socket families. Check the outlet, grounding and device rating before plugging in.
Do you need a travel adapter for Mexico?
It depends on where your plugs come from.
🇺🇸 From the United States
Your plugs fit some compatible outlets in Mexico, but not every listed socket design. An adapter may be needed for the outlet you encounter. Check the actual outlet and preserve any grounding your device requires; hybrid connections may not be grounded.
Mexico uses 127 V and the United States uses 120 V, but similar nominal voltages do not guarantee compatibility. Check that your device's input rating covers the destination supply.

You need a plug adapter. Plugs from the United Kingdom (Type G) don't fit the Type A and B sockets in Mexico. A Type A (US 2-pin) adapter fits the listed socket families there. For grounded devices, get a Type B (US 3-pin) adapter for a compatible grounded outlet instead; it does not fit every listed outlet. Socket variants can differ; check the actual outlet and adapter rating.
Mexico uses 127 V, lower than the 230 V in the United Kingdom. An input rating of "100–240V" covers the listed supply voltage; you still need a suitable plug or adapter. Single-voltage devices may run weakly or not at all.

What to expect in Mexico
Familiar plugs, a different nominal voltage
Electrical Safety First lists Type A and B for Mexico. US and Canadian plugs can fit the corresponding outlets: A has two flat pins; B adds earth. A grounded B plug needs a suitable three-hole outlet. Do not remove its ground pin to use a two-hole socket.
The Mexican national standard published in the official gazette identifies 127 V as the predominant nominal low-voltage supply and 60 Hz as the frequency. Electrical Safety First's travel table instead says 120 V. We retain 127 V from the national standard; those differing figures are not evidence of a regional split.
Does my US device work in Mexico?
Check its supported input range rather than assuming that similar voltages guarantee compatibility. 100–240 V, 50/60 Hz includes the listed Mexican supply. A device marked only 120 V needs manufacturer guidance before use on 127 V. Physical plug fit answers a different question.
UK and European travelers need a suitable A adapter for ungrounded chargers, or a grounded B adapter for equipment requiring earth. A 230 V-only appliance may not work correctly on the lower supply through a plain adapter.
Buying a universal adapter
Verify the wall-side A or B design, accepted home plugs, grounding and rated load. A universal adapter with only two North American pins cannot provide an earth connection. For a Canada and Mexico itinerary, keep checking voltage even where the plug families stay the same.
Will your devices work in Mexico?
Sockets in Mexico supply 127 V. Find the "input" line on each device or its charger. An input rating of "100–240V" covers the listed supply voltage; you still need a suitable plug or adapter. Check that the input frequency also covers 60 Hz. An adapter changes the plug shape, not the voltage or frequency. For switchable devices, follow the manufacturer's instructions before plugging in.
Often rated 100–240 V; confirm on the charger: phone charger, laptop charger, camera battery charger.
Check the label first: electric toothbrush, electric shaver, CPAP machine, hair straightener / curler.
Usually single voltage: hair dryer, kettle / coffee maker, anything with a heating element.
