12 volt power outlet

Plugged into a 110 outlet while the generator is running and charging the main batteries. Just a little extra battery capacity.

We run two CPaps every night. Small draw of power. With ours, we are NOT to use humidifier while on 12v. We have two wire runs from the battery to separate 12v receptacles. Uses MUCH less power on 12V than using our house inverter would. A small inverter will draw less than the house inverter but a 12V plug and cord draws only the power you are using, not wasting any in converting to 110v.

Think you will find the 12v receptacles work well. Good luck!

Respironics BiPAP. Humidifier on 5 (max) 2.67 amperes at 12.24 vdc @ 14 inspiration event.

run the cpap in passover mode and it won't take much power.

That one is easy. The same generator run time that charges the house battery. I fully see the logic of Sam's wanting a separate battery for the CPAP. The furnace can not run down the battery running the CPAP, and they can be recharged at the same time.

At my last physical my doctor seemed surprised I was not on cpap... as if it's normal for older folks. Geesh.. I can breathe fine doc!

I'll be into this soon too.....but have this nagging feeling that it is the money making designer ailment du jour. Guess I'll see if I notice any real difference or not.

Anyhow, my C has a 12 V outlet in the bedroom intended for a TV. I'm hoping that it will work for the CPAP too......but I also intend to try and get one with it's own battery 'cause when it is chilly at night the little furnace takes a pretty big bite out of the battery charge just by itself (along with other incidentals).

You just need to pull the wire from the battery or the fuse panel to where you need it.
If pulling wire proves difficult and you have a 120v outlet... consider a small inverter.

The label on the bottom of my CPAP says 6.67 amps. Not sure if that is the pump only or if it includes the humidifier, which is detachable. I'd be more comfortable with a separate fused outlet for it. Check your CPAP, which may have different requirements.

Also, do you have the manufacturer's 12V cord for it?
