Power Inverter Question

When I was assigned my truck, they installed a power inverter in my truck since I had a cpap. But lately since I have been out west a bit in cold temperatures, my batteries drain during the night and my cpap turns off, and I guess the batteries arent low enough to turn the truck on. Anyways my question is this:

My cpap is plugged into the little cigarette lighter thing, forgot the name of it and not plugged directly into the inverter. would it make any difference power wise, if I plugged it into the power inverter over the cigarette lighter plug? I have cords that can go into either one.

One thing is for sure, its getting annoying waking up to my cpap turned off and I have to idle the truck for a bit manually.

I realized how dumb this question was considering its drawing power from the same power source.

Not dumb at all. There should be a cigarette lighter outlet that doesn’t turn off. If not, use the inverter.

If you're engaging the Opti Idle, the batteries should never drop more than 25% of their charge.

Yeah, that's the thing. It seems to only turn off my power plugs, the lights still work and when I get up, the truck turns on fine when I manually start it. But if I wait for the truck to start itself during opti idle, then itll be another hour or two after my cpap turned off.

I thought about just leaving my marker lights on to help speed up the progress of when the truck idles, especially during the winter months when the batteries drain a bit faster it seems.

Like right now, I've only been parked 4 hours give or take and my batteries are low to the point it cut off my cigarette lighter plugs, my lights work and what not. Thinking my batteries might be going bad?

Not powering anything currently, I charged my phone for a little bit but that's about it.

Should've looked more into my power inverter because I just seen they also included a back UPS 425 which is a backup battery and surge protector which is hooked up to the inverter, which also seems to be hooked up to another inverter?

I hooked my cpap up to the inverter and also tried the backup power supply and worked fine. Cant believe I didnt notice this before.

Forgot to mention both power inverters seemed to be plugged into the batteries, but only one of them was on.

Hopefully, you figured out the fix! Hope it all runs smoothly in the future.

The truck will turn off the lighter outlets when the charge drops below a certain percentage. Then when it drops further, it will start to charge the batteries.

There should be one outlet set up to not turn off for cpap users.

The inverter should be directly connected to the battery and therefore will not be shut off.
