Mexico Electrical Outlets 2026
Plug types, voltage, and frequency for Mexico. Essential info for travelers.
Overview
Mexico utilizes the Type A and Type B electrical plug systems which are identical to those found in the United States and Canada. The standard voltage is 127 volt at a frequency of 60 hertz which makes it compatible with most North American appliances.
Do you need an adapter?
Travelers from North America typically do not need a power adapter when visiting Mexico because the sockets match their home equipment. Those arriving from regions with different standards such as Europe or Asia will require a universal travel adapter to fit the flat pin sockets.
Safety notes
Visitors should verify if their high powered devices are dual voltage to ensure safety with the 127 volt supply. While modern electronics usually handle voltage fluctuations using a surge protector is recommended in areas where the electrical grid may be less stable.
