30-Watt AC Power Supply with Cord

  • Brand:ResMed

ResMed's S9 Series CPAP/BiLevel machines use an external power supply with AC Power Cord. There are two versions of the power supply: a 90W version which is supplied as standard with the system, and a 30w version available as an optional accessory. Both power supplies are designed for universal inputs of 100-240V, 50-60Hz and can be used in most countries around the world.

This S9 Lightweight 30W Power Supply is smaller and lighter than the 90W version and should only be used to power the S9 CPAP/VPAP unit. It is not designed to power the H5i Heated Humidifier or heated tubing.

Usage Information: This 30W Power Supply includes plug adapters for use in North America, Great Britain, Europe, Australia, and other countries around the world.

  • Don't lug around that heavy converter


    If you can get along without using the humidifier for the S9 CPAP/BiLevel machines, reduce the weight you carry around by replacing the usual heavy Power Supply with the Lightweight 30-Watt model. You'll be happier when you travel.

  • Used for long distance flights


    I bought the power adapter because I travel 2-3 times a year Asia. I'm lucky enough to fly in Business class so I have access to power for my cpap. My experience is that using the normal brick draws too much power so I bought this power brick. It works great, never had a problem on BA or LH with it. I'd prefer a plug that is separate from brick, as it awkward having them together. They also included a bunch of different international plugs
