The more and more I research, the more I realize that I may need to pay out of pocket for a new CPAP machine...
I have a Fisher & Paykel HC234 machine. It does not work with DC power, only AC. The manufacturer states that it works with 110-120V at 1.2A (max of 1.3A).
I did some research and people were recommending using a deep cycle motorcycle (or jetski) battery. The deep cycle allegedly handles being ran down better than a traditional battery.
Next, I was going to use a modified sine wave inverter that I have (400W continuous, 800W max) to go from the battery and output to a standard AC plug. Then, I was going to plug the CPAP machine into the inverter.
One issue I have run into is that I hear people talking about using pure sine wave inverters, rather than modified. I can't find any info about whether the HC234 requires a pure sine wave. Judging by the reviews on Amazon, I will have to spend almost $150 for a good pure sine wave inverter.
Anyone know if I can get away with using the modified sine wave inverter I have now? Anybody see any "issues" with my proposed setup?
We have a Honda EU2000i generator that we will be using intermittently, but I'm trying to prevent having to use the generator all night long to run my CPAP.
Thanks in advance!
