Note that it IS possible with this multipurpose device to apply 14.2 VDC to a "cigarette lighter" and keep the main rails at the higher voltage in case of the dreaded BECM issue.
I thought I heard that was a proposed "bandaid" fix. Just a thought...

The "cigarette lighter" would not handle the power requirements reliably.
Why? The lighter port can handle 20A, maybe more. You have a 18A charger.

And there're terminals under the hood with 12V from the battery to use for "jump-starting". You could use them.

Your design needs a 20A fuse or circuit breaker in a line just in case of a short circuit event...

There must be something wrong with my passenger lighter port. It did not want to work.
I wanted something in the trunk area as I always back-in to my flying spot.
A 20 amp in-line fuse is a GREAT idea, thanks.

That's why, then. Those outlets shut down a little while after you turn off the car. Where "a little while" is ten minutes or you open the door, whichever comes first.

You missed the part where DVB said
