Power Outlets & Plugs in Mexico

Mexico uses Type A/B sockets at 127⁠V / 60⁠Hz. Dual-voltage (100–240V) devices need only a plug adapter; mismatched single-voltage appliances must not be connected directly. Replace high-power heating appliances with a model rated for the destination.

Mexico outlet FAQ

Can I charge my phone in Mexico without a converter?

If the actual input label says 100-240V and supports the local frequency, no voltage converter is needed. A typical charger profile does not verify your own unit. Chargers rated (100–240V) — you only need a plug adapter.

Is 127V dangerous for US devices?

Mexico runs 127V, close to the US 120V, but a shared voltage zone does not prove compatibility. The exact input range must include this voltage and the local frequency.

What plug type does Mexico use?

Mexico uses Type A/B sockets at 127⁠V / 60⁠Hz.
