Let me think this through; If I put a voltage regulator on the output side of my charge controller, I could set it to deliver 12V to the car charger when my charge controller is delivering 9V to it. Then when my panel is producing 12V, that means (about) 15V to the car charger. Most cars are north of 14.5V anyway with the motor running, so that seems ok. The car charger does the handshake, making the camera happy, presumably handling its own voltage reduction to provide the qualcomm approved levels.
I pay an efficiency penalty, but my panel theoretically makes double the wattage I need, so I have some capacity to work with.
That might work. I’d be in $14 for the charger and $8 for the voltage regulator
