Power Outage and Cpap Use

[AndrewP]

Hello !
I wasnted to share this with anyone who might find it useful.
I have always wondered if I could run my cpap on a portable car battery charger/jumper if I lost electrical power.
Well, I tried it last night and it worked great. I bout a 600 amp portable car jumper, and charged it at the hospital where I work, which has electrical service. I took it home to my house which has lost electrical service, and plugged my cpap into it using the cigarette lighter adapter. I ran my machine for 10 hours with no problem. I was very surprised and pleased that it ran that long, especially since my portable wasnt even fully charged.
I wanted everyone to be aware of this option if they were going to be stuck in a spot without power.
I was never sure if this would work, but it seems to work great.
I hope this hepls !!

awesome! i'm gonna order the 12v adapter for my unit. question - did you run it with the humidifier? i seem to remember reading the humidifier won't run with 12v - thanks!
UPDATE: I did a little searching - so the 12v dc adapter is roughly $80. and that means no heated humidifier (i imagine the humidifer wouldn't cause an issue if it was left switched off, i.e passive mode.
i see a pure sine wave inverter (180 watt) for $99 at theinverterstore.com (i haven't checked other sites yet)

i read from prior posts that if it is not a pure sign wave it can damage the unit.
now, i believe the 12v dc adapter will be a bit more efficient - no need for a cooling fan, and it is not running the heater. from the owner's manual, it indicates the machine uses 110 watts with the heater - so i'm wondering if the $100 inverter will do what we want (can always shut the humidifier) - thoughts? (my concern is if i get a power failure at home during the summer when there's a storm - that seems to happen once or twice a summer. my intention is to plug the inverter (or if i buy the 12v dc adapter) into a car charger/12v supply i have) - thanks!
