Can I Use My CPAP Machine in United States?

Good to go

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.

VerdictGood to go
Look for "INPUT 100–240V" on the label. If it says "120V" only — do not plug it in abroad without a converter.
For medical devices, always confirm voltage on the label and check with the manufacturer when in doubt.

FAQ

Will a travel adapter let me use my CPAP machine in United States?

United States sockets use Type A/B. Your plug already fits, so no adapter is needed.

Do I need a voltage converter for a CPAP machine in United States?

No. If your CPAP machine is dual-voltage (100–240V), you don't need a converter in United States.

What plug type does United States use?
