在Brazil可以使用CPAP Machine吗？
可以使用——但需要适配器。 电压没问题。只需要对应的插头形状。不需要变压器。
可以使用——但需要适配器。
您的设备支持该国家的电压，但插头形状不同。您需要一个插头适配器才能插入当地插座。插头适配器只改变插头形状——不改变电压，在这种情况下没有问题，因为您的设备已经支持当地电压。
简短答案
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: 127V / 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.
