in addition to shutting off/down the humidifier, don't use a heated hose. since this is a bipap not a cpap I "assume" it uses more electricity ?????????

also, most/all of the newer CPAP/BiPAP machines have internet connection as well. I turn mine off when using it in the trailer. Every little bit of power reduction helps.

And for the heated hose, Resmed makes a insulated sleeve for the hose. I have one on mine. if you want/need to use the heated hose it will reduce the power draw.

another option for the water tray is to fill it with warm water before sleeping. Even w/o the heater on it will offer some humidification and warm water helps for at least part of the night.

I can get 3 nights out of my portable battery pack if heater is off, hose heat is off, wif is off. If the water heater is on I can usually get one night, on cold days, not even one night.

Big clue on what draws power!

360 watt hours at 12 volt is 30 amp hours.

The CPAP likely does not use all that.. but (Due to conversion loss in the power converter/brick/wall wart) but that's figure 30 amp horus.

NOTE there are other loads on the battery 24x7


Home was where I park it. but alas the.
