Power Plugs & Voltage in Mexico
In Mexico, the standard voltage is 127V at 60Hz, and plug types A, B are used.
Your plugs (Type A, Type B) fit Mexico's sockets directly.
Same as home. Any device that works there works in Mexico.
Check your charger Most phone, laptop and camera chargers are dual-voltage (look for “INPUT: 100–240V” on the label). Those only ever need a plug adapter, never a voltage converter. High-wattage items with heating elements (hair dryers, straighteners, kettles) are the usual exception.Mexico mains: 127V, 60 Hz.
Note Type A/B like the US, at a nominal 127V 60 Hz — US devices work without an adapter.
Plug types in Mexico
2 flat parallel pins (ungrounded, North America / Japan)
2 flat pins + a round grounding pin (North America)
Many modern chargers, laptops, phones and cameras are dual-voltage: their label reads INPUT: 100–240V. Those work anywhere in the world with just a plug adapter — no voltage converter needed. Only single-voltage, high-wattage devices (hair dryers, travel kettles, straighteners) are a real concern in Mexico’s 127V supply. Always check the label on your own device.

Frequently asked questions
What plug type is used in Mexico?
Mexico uses Types A & B plugs. Type A/B like the US, at a nominal 127V 60 Hz — US devices work without an adapter.
What voltage is Mexico?
The standard mains voltage in Mexico is 127V at 60Hz. Most modern chargers and laptops are dual-voltage (100–240V) and work fine; single-voltage appliances from a country with very different voltage may need a converter.
Do I need an adapter for Mexico from the US?
Mexico accepts US-style Type A/B plugs, so a plug adapter may not be needed — but check the voltage: the US is 120V and Mexico is 127V. Use the checker above for your exact home country.
Do I need an adapter for Mexico from the UK?
Yes. UK Type G plugs don't fit Mexico's Types A & B sockets, so you'll need a plug adapter. Voltage is 127V — check whether single-voltage devices need a converter.
