There is a design error with dc input on all s8 series machines.
You cannot use them directly from 12V, otherwise it will blow up as
mentioned by cpap.com.

Instead of buying RESMED convertor at a ridicilus price (the converter
converts 12V DC to 12V DC by the way ) you can buy 12V DC-110V AC
converter at a much lower price and can use it for other devices too.

True, but for RESMED S8 it needs to be a pure sine wave inverter, otherwise you will kill the S8.

This is one of the principal reasons I chose a REMstar Auto instead of the S8.

Inverters

Tech support at Resmed says the S8 series will work fine with a modified sine wave inverter, except if you use the heater option. Then you have to use a pure sine wave inverter.
