Travel adapter from Peru to Mexico — do you need one?

Q: What plug is used in Mexico?

Compare the plug shapes, voltage and frequency in Peru and Mexico, and find out which adapter you need before you travel.

No adapter needed

You will not need a plug adapter — Peru and Mexico share at least one common plug shape (Type A, Type B). Voltages differ (230 V at home vs 127 V abroad), so check the label on each device. Most modern dual-voltage chargers handle the swing without a converter, but heating appliances usually do not.

Voltage converter may be needed. Check your device label — most modern electronics (phones, laptops) support 100–240 V and only need a plug adapter. Hair dryers, kettles, and older appliances may need a step-up or step-down converter.
