Brazil: 127V or 220V?

Direct answer

Brazil: 127V or 220V?

Brazil uses multiple nominal systems, including 127V and 220V, at 60Hz. National evidence does not verify a city or hotel outlet; confirm the exact supply locally.

Updated 2026-10-25

Always confirm the voltage of your specific city or hotel before plugging in. The frequency is 60Hz nationwide.

Read AC INPUT on the actual device or power supply. A rating such as 100–240V describes voltage; frequency, plug, grounding and manufacturer instructions still need separate checks. USB OUTPUT is not a mains input rating.

If your device is single-voltage, check the outlet or ask your host for the local voltage — do not assume.

Sources and limits

What the evidence covers

A source supports only the facts, socket types or models listed below. A model example does not verify every device in its category. Confirm your own label and outlet.

  1. ANEEL PRODIST Module 8: Nominal voltage systems · checked: 2026-07-17

    The existing country evidence record identifies multiple nominal systems, including 220/127V, and a 60Hz reference. Module 8, nominal low-voltage systems; existing country evidence record. This verifies national variation, not individual city or hotel voltages. A fresh automated fetch returned HTTP 403 on 2026-09-04; the original review date is retained.

    The reference table compares national voltage, frequency and plug letters. Physical fit alone does not establish electrical compatibility. International mains table and disclaimer. Non-binding corroboration. Some entries differ from national sources; use each country’s claim-by-claim evidence, including unresolved types. This is not a complete source for every country mentioned.

Brazil examples

Brazil voltage examples to verify

Brazil is a city-and-building check, not a single national-voltage lookup.

127V Confirma la toma concreta con el alojamiento o la empresa de electricidad. El nombre de una ciudad no verifica la toma.
220V outlet scenario A confirmed 220V outlet is outside a 120V-only rating. Do not connect that appliance directly.
Best default Read AC INPUT on the actual device or power supply. A rating such as 100–240V describes voltage; frequency, plug, grounding and manufacturer instructions still need separate checks. USB OUTPUT is not a mains input rating. If the exact input rating or restrictions remain unknown, do not connect the device. A voltage converter is an option only when both manufacturers permit the actual load and use; it does not resolve unknown frequency or grounding.

Mixed-Voltage & Plug-Shape Traps When Traveling Some countries combine unusual voltage with familiar-looking plugs — the Philippines (230V nominal, Type A/B), Thailand (230V with US-shaped sockets), Japan (100V with a 50/60Hz split), and Brazil (127V vs 220V by city) are the classic traps. What Does "100–240V" Mean? (Dual Voltage Explained) An input rating of 100-240V covers nominal voltages within that range. Confirm the frequency, plug, grounding and exact model instructions separately; the range is not permission to use every outlet. What Happens If You Plug 110V Into 220V? A 110–120V-only device plugged into 220–240V receives roughly double the voltage it was built for, which can make it overheat, smoke, or catch fire.

Guidance only — not professional electrical advice. Always confirm against your device's label before plugging in. Local wiring (especially in hotels and older buildings) can vary.
