Well, after researching everything, and hearing everyone's feedback, I sucked it up and ordered the converter. It is $80 and comes with a battery connection. I found a 10% off coupon online, for 1800CPAP.com. Next, I'll pickup a battery from Costco, then do some in-home testing before my trip! Thank...

i've spent hours reading through those old threads and none of them explain the difference in efficiency between an inverter and converter - other than to say "an inverter uses more". so, that was my original question. if i go with an inverter, which looks cheaper, then how much more battery will it...

thank you for your help. yeah perhaps i need to suck it up and just go with their converter. i have a feeling there isn't anything special about it… probably just trying to make some extra $$ from us. thanks again for looking around for me.

possible dc power plug… need to figure out the barrel size...

i've only been using the machine for two weeks and i have never tried it with the humidifier off, so no idea how well that works for me. i live in santa cruz… not a dry climate, so it might be fine.

yeah, i have a battery charger i'll bring along in the rv to recharge the battery during the day…

i'll do some looking around for the barrel connector. gosh, it would be nice to find a cheap converter setup like this and save people money.

ver2go, Well, that $16 converter looks a lot better than a ResMed $85 one, but I don't know how to wire things up like that… I guess I'd need to find the other end that goes from the converter wires to the CPAP unit… You mentioned that an inverter is not as efficient… that was my original question. ...

Okay, sorry, a little background… I'm going to be staying in my RV for a week. I can run the generator during the day but not at night. So I was thinking of picking up another RV house battery (deep cycle?) for about $75 (local Costco has them) and then going with either an inverter or converter to ...

yes, i'm planning to put a battery setup together. sounds like i need to get a 12v->24v converter. but why not use an inverter off the battery instead? from what i've read, there isn't an issue with square/sine waves, but i need to double-check that as well. maybe i'm just being cheap here and shoul...

It looks like my AirSense 10 requires a 12v->24v converter. I've read through a lot of the threads here about battery backups, but I haven't found any info about how an *inverter* compares to the *converter* that is recommended by ResMed. Inverters are cheap, compared to the $85 converter ResMed sel...
