How Does Electricity & Plugs Work in Brazil?
Last verified: 2025-06 · Americas
1The Quick Answer
Brazil uses Type N plugs (two round pins plus a grounding pin) as its national standard, but voltage varies by city — São Paulo and Rio are 127V while many other cities are 220V.
2What You Need to Know
Since 2010, Brazil's official standard is the Type N plug (NBR 14136), but older buildings frequently still have Type A, B, or C sockets that may or may not accept Type N plugs. The voltage situation is uniquely complex: São Paulo and Rio de Janeiro run on 127V, while most other Brazilian cities — including Brasília, Salvador, Fortaleza, and Manaus — run on 220V. Some hotels have dual-voltage sockets. Most modern electronics (phones, laptops) have universal 100–240V adapters built in, but always check before plugging in a device like a hair dryer or travel iron.
3Practical Tips
Practical Tips
- 1Check the voltage label on every appliance before plugging in — a 127V device used in a 220V city will be instantly destroyed. When in doubt, ask your hotel.
- 2A universal travel adapter with a Type N outlet is the safest single purchase for Brazil — it covers both the plug shape and adapter needs.
- 3USB charging is universally 5V regardless of local mains voltage — charging phones and tablets via USB is safe everywhere in Brazil.
Important Warning
Brazil's split voltage system (127V vs 220V by city) is a genuine risk to electronics — plugging a 127V-only device into a 220V socket without a transformer will permanently damage or destroy it.
How does this compare?
Electricity & Plugs rules in nearby and similar countries:
Mexico uses Type A and B plugs at 127V/60Hz — identical to the USA and Canada, so North Americans need no adapter whatsoever.
Canada uses Type A and Type B plugs (same as the USA) at 120V/60Hz — North American devices work perfectly; European and UK devices need an adapter and possibly a voltage converter.
Argentina uses a unique Type I plug (three flat pins in a triangle shape) at 220V/50Hz — most visitors need a specific adapter.
