Brazil Power Plugs, Sockets and Voltage

Which Adapter You Need for Brazilian Power Outlets

You step off the curb onto Copacabana's promenade at 10pm, phone at 12 percent, and realise the charger in your bag ends in two round pins that don't fit the three round holes staring back at you in the hotel wall. Here is what you need to know before you pack.

The Short Answer: Type N Sockets, Two Voltages

Brazil uses Type N sockets (NBR 14136). These have three round pins in a triangular arrangement and come in 10 A and 20 A variants. Type C Europlugs, the standard two round pin plug found across Europe, fit most Type N sockets here and draw up to 2.5 A. A universal travel plug that includes the Type N fitting will cover every socket you encounter.

Voltage is the trap. Brazil uses 127 V or 220 V, depending on the region. Rio de Janeiro and most of the Northeast run on 127 V. Brasília, much of the interior, and parts of the South run on 220 V. You will find both voltages in the same city, sometimes in the same building. Plug a single voltage 127 V hair dryer into a 220 V socket and you will smell burning plastic within seconds. Damage is immediate and irreversible.

Voltage	Where It Applies
127 V	Rio de Janeiro, most of the Northeast, many coastal areas including São Paulo city
220 V	Brasília, much of the interior, parts of the South and Northeast

What Works and What Will Break

Dual Voltage vs Single Voltage

Dual voltage electronics (laptops, phone chargers, camera batteries, most USB powered devices) will work on either voltage. Check the power brick. If it reads "INPUT: 100 240 V, 50 60 Hz", you are safe. Just swap the plug shape.

Single voltage devices (most hair dryers, flat irons, curling wands, electric toothbrushes without a universal power supply) will fry at the wrong voltage. Do not plug any of these in without verifying the label. The mains frequency across Brazil is 60 Hz, so a 50 Hz motor will run slightly hotter and slower. This matters for clocks and electric shavers. For most travellers, it does not matter at all.

USB Charging in Hotels and Transport

Hotels and hostels built or renovated since the mid 2010s commonly include USB A ports. Newer and upscale properties may offer USB C. Do not count on USB C being available. Carry a wall charger and a cable. On intercity buses, executive and sleeper class buses on long distance routes often have USB A ports at each seat. Conventional buses do not. Domestic flights on narrow body aircraft do not have USB ports at all. Some newer planes may offer USB A, but you cannot rely on it. Charge your devices before boarding.

What to Pack, What to Skip

Pack exactly one universal travel plug that includes a Type N (Brazil) fitting. Do not bring a dedicated Brazil to Europlug connector. Bring one that works for multiple countries because you may transit through a hub that uses a different plug. Do not bring a single voltage hair tool unless you are willing to buy a local one at a Brazilian pharmacy. Expect to pay between R$30 and R$80 at a store like Magazine Luiza. Bring a power strip with surge protection if you carry multiple devices. Many hotel rooms have one usable outlet, hidden behind a bed frame. A short extension cord saves the trip to reception.

Carry a portable power bank. You will spend full days out, often 12 hours between accommodation. Cafés have Wi Fi but outlets are scarce. A compact unit that fits a jacket pocket and charges a phone twice is the right size. Anything larger stays in your bag.

When the Socket Problem Gets Worse

The failure case is 1am in a Rio hostel with a dead phone and a charger that physically fits but delivers nothing. The socket is 127 V, your charger is dual voltage, but the connector is loose. Type N sockets grip firmly, but worn Europlug pins can sag, break contact, and leave you with a warm brick. If your plug wobbles, wedge a toothpick between it and the socket wall. This works. Do not jam a metal object in there.

If you arrive without a travel plug, Brazilian electronics stores (Magazine Luiza, Fast Shop) and airports sell universal units. Expect to pay between R$30 and R$80. Avoid the street vendors selling unlabelled units at the bus station. Those have no surge protection and may deliver 220 V when you expect 127 V.

Common Questions

Do I need a voltage converter for Brazil?

Only if your device is single voltage and does not match the outlet. A dual voltage device (100 240 V) needs only a plug adapter. A single voltage 127 V device plugged into a 220 V socket will be destroyed. A single voltage 220 V device plugged into 127 V will run slowly or not at all, but will not be damaged.

Will my US two prong plug work in Brazil?

No. US plugs (Type A and B) do not physically fit Type N sockets. You need an adapter that converts US pins to the Type N three round pin arrangement.

What is the difference between Type N 10 A and 20 A?

The pin diameter. The 10 A variant has 4.0 mm pins. The 20 A variant has 4.8 mm pins. Both accept Type C Europlugs. Your universal travel plug with a Type N fitting will work in both.

Can I charge my phone on Brazilian buses and planes?

Some long distance executive and sleeper class buses have USB A ports, but conventional buses do not. Domestic flights do not have USB ports on narrow body aircraft. Newer planes may have USB A, but it is not standard. Charge before you board.

Is USB C common in Brazilian hotels?

Present in some newer and upscale properties, but not widespread. Bring your own USB C wall charger. Do not rely on the hotel providing one.

What happens if I plug a 127 V appliance into a 220 V socket?

Immediate damage. The appliance will overheat, smoke, or blow an internal fuse. The smell is unmistakable. Unplug it and accept the device is gone.

Where can I buy an adapter if I forget mine?

Electronics stores like Magazine Luiza or Fast Shop, and airport shops, sell universal travel plugs. Expect to pay between R$30 and R$80. Street vendors at bus stations sell unlabelled units. Avoid those.
