CPAP Battery supply?

Was wondering what one would do to run a RESMED10 on a battery supply.
We will be traveling here shortly and may be off grid a few nights. Any suggestions? I did purchase a 150w portable battery from Amazon but it would only power the unit 6 hrs.

I am guessing the CPAP is a 110 volt unit?

If so, why not get a small inverter that will provide 110V from the RV batteries?

If the RV batteries need a charge and you are dry camping, a solar panel might be all that you need, depending on load, to keep the batteries charged.

They offer converters that will power your device from 12 volts DC. https://www.resmed.com/us/en/consume...equipment.html

Most of major CPAP manufacturers offer some sort of portable battery supply for use with their equipment, but often they are expensive and generally supply power for brief periods of use (usually on the order of hours). One trick I have seen used in the Missionary field and in other situations where users will be off grid for extended periods of time includes a deep cycle battery and an appropriate ďclip onĒ inverter. CPAP run time is usually measured in days and the only down side being bulk. In fact, Iíve seen that set up in a number of brick and mortar homes that are subject to frequent power outages or are remote from the local utility providers and whose electrical service is slow to be restored after outages.

That would be an "inverter".

The air pump in a CPAP is not the "power consumer". It's the heating circuit for the humidifier. The humidifier can be turned off as can the heating element for the "hose temperature". With those two features off, the system will run on a "Shumacher jump starter/inverter/compressor" for 3 nights (about 20 hours).

There are other means to power the CPAP, buying a 12VDC adapter for the device, buying a "stand alone inverter" and using the trailer battery being the most popular.

Here is the Shumacher jump starter we use. It's available at Lowe's and many other stores. https://www.lowes.com/pd/Schumacher-...ter/1000569111

The description on their site indicates the device connects directly to 12 vdc to power the cpap machine and works just like the battery. Donít know what the standard battery voltage is, so possibly the conversion is from 12 V to whatever the cpap needs for voltage.

I am in the process of installing a pure sine inverter in our Passport Elite TT to power my Resmed CPAP. Resmed advised me that it would require a 300/500W pure sine inverter.
