Think it has a 10 to 18 ah battery in it. Last an hour or two.

The most noise come from the exhaust .

If you leave the exhaust in the dog house it will kill the engine faster then the dog. They both need oxygen.

Not true. Here is a battery sold to power the ResMed AirSense10 CPAP and it will power the CPAP from between 5 - 20 hours depending upon air pressure setting...... Turn off heated humidification as heating the water is the power hog.

This battery is 100 Wh which is smaller than the one I posted earlier.

Based on 30 Ah/night true. You are talking about apples, oranges and bananas. There are portable CPAP machines that use less power but the 12 v device you showed is for starting vehicles and has a small AGM Battery with no 12 v terminals. Plug the CPAP into that via the jump cables and send a picture please.

The CPAP 12 volt adapter has a "lighter plug" male end which plugs right into the 12 volt socket on the jump starter. I have this exact JNC 660 jumper box and it is awesome. Very powerful and portable.

Here is the DC converter kit for the ResMed S9 series CPAP machine which I have.

Plugs right into the 12 volt port on the above battery.

Why not plug it into the RV then?

Generator "quiet box"

Because the OP only has a TT with one battery !

The portable battery is a much better option then him trying to silence a noisy generator to run the CPAP.

Maybe when he has the time or inclination adding a second battery to the TT would be a good option...but that takes time and effort vs a ready to go solution.

These sound dampening covers have been built to reduce the noise from shop vacs (Google Link: https://www.google.ca/search?q=sound...w=1116&bih=575).
The key is to redirect the flow of sound using baffles and a sound absorbing material, in the case of a generator I would also install a 120 Volt fan inside the box for air flow. I'm certain, when done properly the sound level can be reduced by more than 50%.

Many "boondocking" areas including BLM have "quiet hours" which mean NO generators for ANY reason during those hours...

Thanks for all the info. As usual in a post I wasn't clear about the uses of the generator. I also need it to run my 13,500 AC unit and other items such as a TV, computers, etc. When I'm at a place to where I have to use a generator (so far) I have had no neighbors within a couple 100 yrds at least. If so I'll move to a park w/power. The box use was strictly for my use to quiet down the noise I have to hear. The generator is the main problem I'm dealing with which is covered in other threads. Probably end up buying a Champion. Once again, thanks for all the information on CPAPS and accessories available. I love this forum and all the information a rookie like myself can learn from.

So if you buy a loud champion, than you are not helping the problem you have of generator noise.

If you simply can't afford one of the quieter generators, then that is one thing. If you can and you decide not to, then you have to build the box, cart it around, etc. Even the quiet gennies can be a little loud at full roar to run an air conditioner, but the quieter ones are, well, less loud, so you're taking a huge step towards helping the noise problem that you came here seeking help advice about.

Don't just "settle" for a loud generator, make sure it's the one you have to have, or the only one you can afford, if you have to have a gennie running all night.

It was my understanding that the Champion's were just as quiet as the Honda's.
