Sorry never gave a thought to running a bunch of devices from the lighter. I have old cars that go to shows and putt around town, and new cars that are loaded with extra stuff to plug in to a lighter. Never made the leap that some folks would be using the antique car as a modern transportation device in daily service.
Rather dumb on my part I guess.
If you are going to power GPS, laptops, i- whatever gismo, inverters etc. than up the amount of amps available to that circuit bypassing bulkhead connector, using #10 or #12 gage conductors with appropriate fusing. I would operate it via a relay triggered from ACC circuit and run ignition circuit.
