    Important Tips

    Important Note For RESmed S8 and S8 II Machine Alone Use: YOU MUST USE an appropriate converter such as this product to draw power directly from a DC battery source to connect to an S8 and S8II machine alone and provide power. Failure to do so can result in damage to your machine.

    Using a ResMed S8 machine with a Humidaire H3i or H4i: A pure AC power source is required in order for the humidifier to work properly. The machine disables the humidifier when connected through DC Power. Use a pure sine wave inverter to provide pure A/C power to power both the machine and heated humidifier. An example of this type of inverter: DC to AC Pure Sine Wave Power Inverter.

    ResMed VPAP Auto 25 and VPAP ST: ResMed VPAP Auto 25 and VPAP ST use a different cord, DC-24 Converter For ResMed. Refer to the Respironics Battery Kit for ResMed VPAP Auto 25, VPAP Malibu & VPAP ST Machines for a battery kit for these machines.
