Using Your CPAP Machine Abroad

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

  1. Find the small print on the device, plug, or power brick.
  2. Read the INPUT line.
  3. "100–240V" means dual voltage (safe worldwide); a single value like "120V" means single voltage.

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.

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.
