Can I Use My CPAP Machine in United States?

Q: What plug type does United States use?

United States uses Type A/B sockets at 120V / 60Hz.

Check your CPAP machine's label before using it in United States.

Why

Compatibility is unconfirmed. Read the exact INPUT voltage range and frequency on your device or power supply, and compare them with the destination. The whole local range must be covered; 110–220V does not include 100V or 230–240V. Confirm the actual plug, grounding and manufacturer restrictions. Do not plug in while these details are unknown. 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 / 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.

Scope

ResMed: AirSense 11 user guide: The guide specifies 100-240 V, 50-60 Hz, typical/peak consumption, and Class II equipment. These values apply to AirSense 11, not every CPAP.
Philips: DreamStation BiPAP autoSV user manual: The manual specifies 100-240 VAC, 50/60 Hz and Class II equipment for this model. Exact medical-device instructions remain model-specific.

Find the INPUT label first. If the label is missing or unclear, do not plug it in and do not buy a converter on guesswork.

For medical devices, always confirm voltage on the label and check with the manufacturer when in doubt.

FAQ

Can I use my CPAP machine in United States?

Check your CPAP machine's label before using it in United States. United States runs 120⁠V / 60⁠Hz on Type A/B sockets.

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

Not by itself. First check the label — if your CPAP machine is single-voltage, a plug adapter will not protect it from 120V.

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

First check the label. If it says only 120V or only 230V and that does not match United States's 120V, do not buy or use a converter until wattage and local voltage are confirmed.

What plug type does United States use?

United States uses Type A/B sockets at 120⁠V / 60⁠Hz.

Adapter vs converter explained

Guidance only — not professional electrical advice. Always confirm against your device's label before plugging in. Local wiring (especially in hotels and older buildings) can vary.
