inverter

We tried to hook up a 12 V plug by my bed once, and it didn't work very well. *shrug*

we also drug a marine battery into the rv a long time ago, directly hooking up the CPAP with clips, and it stopped in about 20 minutes.

The inverter will use as much power as the cpap machine. Running the cpap direct off the battery is very desirable.

our Class A has an inverter, and we charge the battery during the day. No need for a generator all night. That sure would keep me awake more than the apnea lol I even use my humidifier.

We have a class c motorhome with a good generator. When we dry camp I have to run it all night due to a medical problem. Do you know of an inverter that could run a cpap machine all night?

Been using a CPAP now for about 20-years, & all I do is dry camp. There are many newer models on the market now that operate on AC / DC. Depending on whether you use a humidifier or not, will determine power consumption. With a humidifier, it will consume approx. 4 amps per hour, & that depends upon the model & upon your heat settings etc. I use a small "dedicated" 35amp AGM deep cycle battery to operate mine, but I don't need a humidifier.It will last about 3-4 nights before charging is needed. Another thing, I have a CPAP in the house, another one for the RV & a third as back-up. I purchased the one for the RV off Craig's List. It is a Remstar, & only had 18 hours on it, came with the DC power cord as part of the package ($115) Very small & compact, perfect for an RV. I re-set the "pressure" myself.

Thank you so much. I didn't know a cpap like this existed. I am checking into buying one before the rally in Phoenix.

Hi,

Many small inverters could run a cpap all night. Do turn off the humidifier.

Some units come with a power brick--measure the output--it may be that the unit itself is 12 volts dc already.

How about a 12 volt CPAP
