Mexico is plug-friendly for North Americans and a quiet voltage trap for everyone else. It uses the same flat Type A and grounded Type B plugs as the United States and Canada, running on 127 V at 60 Hz - so US and Canadian travellers can plug straight in with nothing extra. Visitors from Europe, the UK and Australia need a plug adapter, and should remember that 127 V is barely more than half of their home 230 V, so single-voltage appliances won't perform as expected.
| Coming from | Plug adapter | Voltage |
|---|---|---|
| From the United States | Not needed | Compatible |
| From the UK | Adapter needed | Check converter |
| From continental Europe | Adapter needed | Check converter |
| From Australia / New Zealand | Adapter needed | Check converter |
Plug adapters change the shape only. A "Check converter" flag means the voltage differs from your home country - fine for dual-voltage gear (phones, laptops, cameras marked 100-240 V) but risky for single-voltage appliances like hair dryers and travel kettles.

No - Mexican sockets take US Type A/B plugs and 127 V is compatible with US devices.
With a plug adapter, yes for dual-voltage gear. Single-voltage 230 V appliances will not work properly on Mexico's 127 V.
Types A and B - the same flat pins as the US and Canada - at 127 V / 60 Hz.
