Is a CPAP machine dual voltage?

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.

Medical devices need extra care. If you rely on a CPAP machine or any other medical device, check its manual and confirm with the manufacturer before traveling. Many CPAP units are dual-voltage, but heated humidifiers and heated hoses can draw significantly more power and may behave differently abroad. Frequency (50Hz vs 60Hz) can also affect timing on some medical equipment. Do not guess with equipment you depend on — confirm with the manufacturer.

How to read your CPAP machine's voltage label

Find the small print on the device, plug, or power brick.
Read the INPUT line.
"100–240V" means dual voltage (safe worldwide); a single value like "120V" means single voltage.

Common labels: 100–240V 50/60Hz · AC 100-240V ~1.0A 50-60Hz

Label patterns to check before packing

Green-light label "100–240V 50/60Hz" means the voltage range is travel-safe; still pack the right plug adapter.

Single-voltage label A single voltage like 120V or 230V means the device is not universal; match it to the destination grid before use.

Missing or worn label Treat it as unsafe until the manufacturer, manual, or power brick confirms INPUT voltage, frequency, and watts.

FAQ

Is a CPAP machine dual voltage?

Most are. Look for "100–240V" on the label — if it's there, it works worldwide with just a plug adapter.

Can I use a CPAP machine in Europe?

Yes — with a plug adapter for the local socket shape. No converter needed if it reads 100–240V.

Do I need a voltage converter for a CPAP machine?

No — dual-voltage devices never need a converter.

Adapter vs converter · What "100–240V" means

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.
