Mains voltage in México is 127V 60Hz. Travellers from Canada and the US should have devices/appliances with plugs that work on the same mains voltage as México and can make use of existing plugs – therefore you will not need either a voltage converter or plug adapter.

If your country does not use devices/appliances within the 120-127V 60Hz mains voltage range, you will need to purchase a voltage converter. This will transform the voltage from the power outlet into one your appliance can use. You will also likely need a power adapter.

Note: Many modern devices/appliances run on a variety of mains voltages. Your appliance should be marked with this information or mentioned in the product’s instruction booklet; e.g.,a power supply marked as “Input: AC 1.5A 100-240V 50/60Hz” does not require the use of a voltage converter as it works on a mains voltage range between 100V and 240V.

In addition to power considerations, most visitors to México (excepting visitors from Canada or the US) will need to ensure that their devices/appliances have the correct power plug adapter. México uses the international Plug Type A and B standards, which are described further by the International Electrotechnical Commission (see links at right).
