S9TM 30W power supply

S9TM 30W power supply

This product may not be available in all countries.

The S9™ 30W power supply is a small, lightweight power supply suitable for any S9 device that isn't being used with 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 for patients who don't need a humidifier but do want a lightweight, convenient power solution for travelling.
