Are electrical converters needed?
Travelers from North America (U.S. and Canada) generally do not need a voltage converter, as Mexico uses 127V/60Hz. You may need a simple plug adapter for outlets without a grounding hole. Travelers from Europe, Asia, or other regions using 220–240V will need both a voltage converter and a plug adapter. Always check your device to see if it is dual-voltage (typically labeled 100–240V).
