United States to Brazil Power Adapter Guide

United States runs 120⁠V and Brazil runs 127⁠V. You need a Type N/C plug adapter; check each input label before connecting; a converter is not suitable for every appliance.

Caution: United States runs 120V and Brazil runs 127V. A plug adapter changes the shape, not the voltage — a mismatched appliance must not be connected directly. High-power heating appliances should be replaced with a suitable local model; check both manufacturers before considering a converter.

Will my United States hair dryer work in Brazil?

For the typical United States single-voltage model: check its exact label and manufacturer instructions first; the shared voltage zone is not proof of compatibility. Brazil is 127⁠V. Confirm frequency and any voltage selector before connecting.

Is the voltage different between United States and Brazil?

United States is 120V and Brazil is 127V. That difference matters for single-voltage devices.
