S9TM 30W power supply

S9TM 30W power supply

The S9™ 30W power supply is a small, lightweight power supply suitable for any S9 device, if you don't need to use an H5i™ heated humidifier.

The 30W power supply is smaller and lighter than the 90W power supply that comes as standard with all S9 machines. It's a great choice if you don't need an H5i heated humidifier but do want a lightweight, convenient power solution for your therapy device when you're travelling.


Key Features

  • The 30W power supply is smaller and lighter than the 90W power supply, making it great for travel.
  • You can use your 30W power supply unit with any S9 device,  but it does not support the H5i humidifier. If you need to power an S9 machine attached to an H5i humidifier, please use the 90W power supply unit that came with your therapy device.
