CPAP Machine

For a medical device, confirm the exact power-supply label, approved accessories and travel instructions with its manufacturer. A representative CPAP supply does not verify every machine, humidifier, heated hose or battery. Do not guess with equipment you depend on.

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.

How to read the INPUT label

Read the INPUT rating on the exact device or AC supply: V = voltage, Hz = frequency, A/W = current/power. USB/DC OUTPUT ratings are not the AC input range or measured wall consumption. Match the full local voltage and frequency, plug, grounding and manufacturer instructions. A 100–240V label covers only that range; 120–240V does not include Japan’s 100V. If the label is missing or unclear, do not connect until confirmed.

FAQ

Is my CPAP machine dual voltage?

Check the actual input label on your CPAP machine or its power supply. A 100-240V range covers those voltages; confirm frequency, grounding and model instructions separately. Category examples do not verify your own unit.

Can I use my CPAP machine in Europe?

Only when the actual input rating covers the destination voltage and frequency and the plug fits with required grounding. For a medical device, confirm the exact supply and accessories with its manufacturer.

Do I need a voltage converter for my CPAP machine?

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.

Safety check: a plug adapter only changes plug shape. It does not convert voltage, so confirm your device label before buying.

Shopping links never change the safety verdict.

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.
