Easiest and safest way is to add an auxiliary power socket and leave
the factory lighter socket power supply alone, since it has a thermal
protector in it that you can easily trip by running power accessories
for long periods. Plus, having the lighter socket power switched is a
safety measure to keep from lighting the car on fore - it's fairly
easy to drop a parcel or item and push in the lighter element to where
it won't pop out and shut itself off.

Add an auxiliary power outlet under the dashboard. If you only need
5 amps or so, tap off the dome light fuse (or another constant
circuit) at the fusebox - they have "Add-a-Circuit" taps that plug
into the fuse holder prongs and give you a second lead.

How much power do you need for these accessories, and for how long?
(So I can come up with an average amp-hour draw.)

You can't use a lot of power (I'd stop at 5 Amp-hours) with the
engine turned off without deep-cycling and ruining the regular
starting battery - they do NOT like that usage, they are made to give
a big burst starting the engine and then be immediately recharged.

No lighter element came with the car, just the cigarette jack and a plastic
cover. The label inside the cover sais "don't exceed 50W". 50w/12v= 4.1Amps.
I'm way under that.
So I'm not worried about fire or anything dropping in it.
I only plan to use a GPS unit. 300ma. I prefer using the cigarette power
jack. Perhaps I can jumper it to the "Add-a-Circuit" tap. I don't know where
the cigarette power jack wire ends up; in the fuse box or somewhere else ?

The cigarette power jack wire ends up at the lighter fuse.
