Need to run cpap on marine battery
Hi,
I need to find a way to run my husbands cpap machine for sleep apnea. We might have to camp for a night at a Walmart on the way home. Is there a way to do this using the marine battery? Needs to last all night. We have a 2015 tracer air 250. Towing is a 2015 Chevrolet Silverado 1500. The truck has a 110 outlet but not sure how long that would last, or if that would work.
Thanks

Can be done and I have done it. you can use a marine battery if you have the cigarette 12V adapter for your machine and then have the alligator clips with a cigarette socket to clip onto the battery. Note he will need to turn the humidifier off, the only down side. also depending upon how long the adapter is and where your 12 volt socket in the trailer is you may be able to connect directly to the socket in the coach where the TV connection is. My machines all convert to 12 volt to run the blower in the machine. Pep boys has the 12 volt cigarette plug with the alligator clips.

The truck outlet will power it, but I don't know for how long. I don't know what kind of power draw those units have. I'd feel safer if it ran of the marine battery and properly sized inverter. That way, you know the truck will still start AND you have an alternate power source for the cpap if needed.

I have ran mine for two full nights and about 5 hours the third night of a fully charged deep cycle battery while tent camping with my sons boy scout troop. The key is no Humidifier. Also i bought a nice little unit that has its own battery a few years ago and when we went to summer camp for a week i brought the charger and plugged it in at the kitchen every morning to charge during the day. About a year after buying the unit i thought that i would buy a second battery and the factory in China burned down and i could not get one. dont know if they ever rebuilt or not, never checked on it again after that.

Last trip we had a 2 night visitor using a CPAP machine. She did not have a 12V adaptor. We ran it for 2 nights via a 750W invertor/deep cycle battery and battery still had plenty of juice. Year before we had 2 visitors at the same time each using a CPAP machine. Same invertor and battery with no problem.

Not using the humidifier really reduces the amount of power needed.

I purchased a Black and Decker power station from Walmart. It not only will power my CPAP overnight, but it will also top off my tires, power my computer, and jump off my battery. Pretty good investment for me.

Posted many times but here are the two options we use - - DW uses a battery designed for CPAPS. Lasts 18 hours or so. Cost her about $200 and only weighs 1#. I use a 450w xPower sealed battery with jumpers, radio, etc. It lasts a couple of nights on the 12 v side but also has an inverter. It weighs about 35# and also cost about $200 10 years ago. Neither of use the humidifier.

When I tent camped, I found that with the humidifier, I could get about a night and a half of sleep out of a regular truck battery. Without the humidifier, I could get a whole second night with minimal driving of the vehicle after the first night.
In my camper, I just used a cheap 100w power inverter in the camper's only 12v plug in the kitchen and an extension cord to the bedroom. I happily slept for a night that way, towed the whole day the next day, and slept happily the next night.
If I did it more often, I would install a 12v plug in directly in the bedroom. Or better, an inverter-powered outlet above my existing one.
For one night, you don't need anything special. If you do it regularly, then it is something to consider.

I use one of those portable jump start units with a built in inverter for my CPAP if power is out (hurricanes here in FL). Runs it for 2-3 nights on a charge and also gives me an emergency power source when traveling.

We plug a 400 watt inverter into a 12 volt plug connected to the house battery. More than enough power to run my wife's CPAP for the night. The battery is recharged during the day while we're driving.

I ran mine off a 110 watt inverter plugged into the "cigarette lighter" plug on our Windjammer a couple of years ago. Did it twice with no problem. Didn't use humidifier. As I recall I did hook up an extra battery (the trailer just had the one) but I don't think that was necessary.

I purchased the 12v converter to use with a deep cycle marine battery since I use the CPAP on a weeklong fishing trip deep into Quebec. The converter costs about $82 online. I then mounted a 12v accessory plug on my night stand, ran a fused wire into my front storage box where I keep the deep cycle battery. In Canada, I can run the CPAP a week or more without charging. No humidifier or heated hose of course. Very happy with this setup.

CPap power
Got 12v plug from Radio Shack, tapped into my bed reading light wires and installed a 12v socket. Never had a power problem.

Using cpap with inverter
Just got back from our trip to Michigan. Bought an inverter at Walmart. We used it for the first time last night. It worked great. It didn't suck all the power out of the battery, and my husband got a great nights sleep!
Thanks to all for your suggestions. Makes life easier.

CPAP
Many CPAP's will run off 12v. Just need a special plug. Ran mine off a motorcycle battery.

Reading the back of the CPAP, most do use 12v but is converted from the 120. My mother's was as simple was a trip to radio shack and she was using 12v in their Sunseeker.

Just be aware that not all units run off 12 volts.
Respironics and a few others do, but Resmed units use 24 volts.
