anybody use a sleep apnea machine

[jaaybird]

or a loved one?

If we go to Death Valley and no electricty,


I got from Radio Shack, a converter that plugs into the cig. lighter socket
and then I can plug the "regular plug" into that....

QUESTION:
Since we will be in a c/g with NO electricity
and if during the day I use the genset to keep batteries charged
will it run all night and not drain the
coach or starting RV batteries?


Sorry to ramble:

but I can see myself there a hundred miles from nowhere and dead batteries

I have one, but have not personally tried it on battery power. A friend of mine told me his will not run all night on the battery. He thinks it might though if he didn't use the heater AKA the humidifier Personally I don't think I would try it without the humidifier because it would dry out your nose & throat & would probably give you nose bleeds plus a very sore throat. I had to go to a heated air tube this winter to give me more moist air because I started to get nose bleeds. Too dry in the house with the furnace running.

thanks Don, question will it drain the coach starting battery if left on all night?

I have two and both can run directly on 12 volts. Don't know about the new one but the old one would give me 4/5 nights without a charge. I don't use a humidifier so wont comment on that other than the humidifier unit that was offered with the new cpap used no power.
What brand are we talking about ? Mine are Respironics.
Why would you use the starting battery as the house deep cycles are better suited ?

thanks Don, question will it drain the coach starting battery if left on all night?

No it won't drain your starting battery as long as you are hooked up to your coach battery,,, unless of course the isolater relay isn't working.

My machine is a Resmed Escape.

I think he is unsure which battery the cigarette lighter attached to and I have no idea without testing it.
If he can use straight 12 volts that would save energy that the inverter would use.

Cal
I missed that part about the cig lighter . Usually it is hooked to the chassis battery. If he unhooks the chassis battery it will tell him if is.

[Cal]

Reason I do not know is my TT and bro in laws MH have several lighter recepticles in the rigs.

[jaaybird]

thanks everybody!

The machine is a res med
Cal! you are correct..
I think the cig lighter is attched to the vehicle battery not the house battery

will ask my local " wrench turner" next time I see him

OK GUYS........
not to sound stooopid
but

how do you run directly on 12 volts?

if my generator is not turned on
no plugs are hot

how do you get electricty with out a genset?

Quiet hours start at 10 PM

Here is the process you are proposing now. Take 12 volts from the cig receptacle and change to 120 V ac then plug in your machine into that and that black box on the cord [a transformer] changes it back to 12 volts DC . What you need to do is eliminate all of that.
Is your guy an auto electric man also?
If so he can figure out how to do it best for your rig. the main worry is the correct polarity into your CPAP.
Maybe he knows a good auto electric person. you have 12V in your bedroom so all you need is to tap into it. Radio Shack has the end to duplicate the end of your 120V cord.

No sleep machine, but when my wife and I dry camped she ran the TV (CRT) all day long, battery powered, for something to do. In order to do this I did change from 2-6 volt golf cart batteries to 4. I rewired so I had two battery banks and only one bank working at a time. I also installed a larger solar panel to help maintain the batteries better. I only used the genset during meal preparation when the microwave was needed. By the end of day the one battery bank was down to maybe 60% and the other at 100%. The next day I switched to the full battery bank and started the process all over again, switching from one bank to the other each day.

I would think a CPAP machine would use less power than a TV (CRT), but haven't checked it out.

The problem is he has a Resmed machine. Mine is 24V. & his could be the same. Mine is the Escape S9.

JB
Check the label on the back & see what the voltage is.

[Cal]

I Googled up the site and the s9 that I looked a before I posted was a 12/24 V thought they all were?

[Burnerman]

I'll give you the numbers off of the machine
DC24V
1.25A (FG)
3.75 (Sys)
That is the way it is written on the label.
There may well be a 12V unit, because in the book under options it says there is a 30watt power supply unit, but it won't support the H5i heated humidifier. So I guess we will have to wait & see which one he has.
