Can I Use My CPAP Machine in Brazil?
Yes — with an adapter.
Your device handles this country's voltage, but the plug shape is different. You need a plug adapter to fit the sockets here. A plug adapter only changes the shape — it does not change voltage, and that's fine in this case because your device already supports the local voltage.
The short answer
Most modern CPAP machines are dual-voltage (100–240V) and need only a plug adapter — but as a medical device, never assume: confirm the exact label and check whether your heated humidifier is frequency-sensitive. Bring the manufacturer's travel power supply, consider a battery pack for flights, and avoid cheap voltage converters that output a non-pure sine wave.
Brazil runs 127V at 60Hz. CRITICAL EDGE CASE: Brazil has no single national voltage. Most of the south and southeast (São Paulo, Rio de Janeiro) is 127V, while much of the northeast and the capital Brasília is 220V — and both can even coexist on the same street. Always confirm the voltage of your specific city or hotel before plugging in. The frequency is 60Hz nationwide. Brazil uses the Type N plug (its own standard), which also accepts Type C.

FAQ
Will a travel adapter let me use my CPAP machine in Brazil?
Brazil sockets use Type N/C. Yes — you need a Type N/C plug adapter for the shape.
Do I need a voltage converter for a CPAP machine in Brazil?
No. If your CPAP machine is dual-voltage (100–240V), you don't need a converter in Brazil.
What plug type does Brazil use?
Brazil uses Type N, C sockets at 127V / 60Hz.
