Can I Use My CPAP Machine in United States?
You're good — plug right in.
Your device's voltage range matches this country, and the plug fits. You can use it directly — no adapter or converter needed. As a final check, confirm the voltage range printed on the device label.
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.
United States runs 120V at 60Hz. Standard 120V at 60Hz. Type A is ungrounded (two flat blades); Type B adds a round ground pin. A single-voltage 220–240V appliance brought from Europe or Asia will run at roughly a quarter power or fail to start here — but it will not burn out.
