Newly diagnosed with sleep apnea. Insurance requires me to use the CPAP machine (a Dreamstation) a minimum of 21 out of 30 days a month for the first year in order for them to pay for the machine.

We do some boon docking, and have a trip over July 4 where I will be over a week without power at night (will run generator during the day at least 8 hours for batteries in the houseboat).

What are people using for a battery/portable power station in similar circumstances?

Not sure how you could connect an ordinary battery to that DreamStation....but I see they offer a battery accessory as option. Could you see if insurance will cover that being as you don't have power when boondocking? .....it is an exorbitant $300. !!

Edited in retrospect - I see from a subsequent post that a DC cable for the DreamStation CPAP is readily available.....which should take care of the OP's needs if he has ready access to a DC connection to his RV battery bank.....otherwise should be easy to wire in a connection ....

Bipap machine user for many years. Insurance doesn't cover battery power. You can't use just any battery either. The machines are very touchy. If you damage them from hooking them up to a non approved power source, you own a paperweight they won't replace.

They sell battery powered machine you can buy on your own, $700-$1000+. Or you buy their battery packs from the medical supply company.

Read your contract you signed with them. Very important.

Most of these units have a "brick" in the power cord that converts 120 AC to 12 volt dc. Check to see what the power consumption is there.
You should have no problem using either 12 volt direct power to the unit or running an inverter.
DW and I are both on Respironics units, which she also uses the humidifier, and hers still uses about 70 watts.
We have had no problem getting by using them even during power failures at home with a 12 volt group 29 rv/marine battery from my boat.
You may want to add an additional battery to your set up, and allow a little additional charge time when running the genny but you should otherwise be fine.
Edit add,
If you dont want to use an inverter, here is the 12 volt cord for that unit. 12 volt cord

do NOT run the humidifier on days you are without power.
another post reminds me that the dream station comes with a heated hose. just use a standard, non-heated one when no power.

You must have a decent amount of batteries that you need at least eight hours to charge them. Pickup a Victron Phoenix 375 pure sine inverter, about $120 on Amazon.

There's a pretty good forum at CPAPtalk.com with a lot of technical expertise. It isn't a very friendly place, but you can dart in with questions and then dart back out.

Since the CPAP is really a lifetime commitment, you might want to consider just buying your device outright. The functionality and fit of the masks is such a personal decision, but the service from the equipment providers isn't great at all. The providers work for their insurance clients, not for you.

Just like with eyeglasses, you have the right to call your doctor's office to get your prescription. Once you have that, you can upload it to https://www.cpap.com/ and buy your own equipment. Depending on your insurance co-pays, you'll probably save in the long run by buying your own device.

As far as running it in your RV, you have a few options if you aren't already hooked up to shore power. You can get the 12V adapter for the CPAP and just plug it into a 12V outlet if you have one at your bedside. If you don't have an outlet, you can probably pay a mobile tech to install one pretty cheaply.

You can also run a small dedicated inverter from your batteries to your bedroom, but the small inverters don't typically work well with the needs of the CPAP device, especially the humidifier.

If you spend a lot of time in your RV, it's worth it to invest in your power system. You can upgrade to four 6v batteries, add solar panels (a great investment!)), and install a large enough inverter to power your televisions, coffee maker, etc. (and of course the CPAP at night).

It all depends on how much time you spend in your RV and your budget.

Also, if you travel a lot, make sure you have access to your prescription. Save it to your Google Drive or someplace where you can access it from anywhere. It stinks to be on the road and have something go wrong with your device and not be able to replace it without the prescription. If you have the prescription though, you can walk into a CPAP retailer and explain your situation and see if they have an older refurbished device that they can sell you cheaply.

Good luck.

If you can put in a 12v outlet near the bed, this 12 volt cord will probably work fine. Like others have said, the heated humidifier is the biggest power hog on the machine

Get the 12V cord, and have an outlet installed beside your bed. Been doing that for 10+ years, and it works perfect. Only thing though,, at home, if power goes off, lack of air wakes me almost instantly. In the RV, as I am connected directly to the battery supply, if external power goes out, 12V is OK, and CPAP continues running as if nothing has happened. Therefore, I sleep on peacefully. Can be good or bad, whatever.

Even if you are camping far away from others, running a generator eighth hours a day is a pain. With adequate solar panels and batteries on most days you won’t need the generator at all. Since this will unfortunately be a continual issue, get solar.
