I just use the built-in one. I don't rely on it to actually charge the phone to any appreciable degree, but on longer trips, it keeps it from running down while I play music through wireless carplay, or if I have the jb4 app open.
i have this Baseus thin wireless charger ... i disabled the factory charger (phone heater), and laid it on top of that. its powered by a USB adapter in the 12V cig lighter port.

My phone is older, has a wireless charging mod that I can detach from the back of the phone and I place that in the stock wireless charging. Works wonders to keep a decent charge. I don't usually need it to fully charge.
For anyone who wants to use the stock location for an aftermarket one: I disabled the factor one in the menu, and pulled up the rubber piece which frees up a few mm in height.
Then I cut a piece of thick cardboard to sit snugly where the rubber was, wrapped it neatly in electrical tape, and cut a small circle and cable guide to fit a simple aftermarket wireless charging puck. Connected it via 6" USB cable to a low profile cigarette plug (to avoid using the CarPlay/Android Auto USB outlet).
I'm sure someone could make a nicer version with a 3D printer, but this one holds the charger in place and disappears in the stock location...can't even tell it's not stock.
I've had 2 previous phones (both OnePlus) burn up the USB-C port while charging via USB-C. Not in the car, but at home overnight. This made it so that I had to use Bluetooth and WiFi to transfer all important files off of my phone with little battery remaining.
That interface, the USB-C (or whatever plug) is the weak point because so much runs through it. We don't have phones where you can easily swap the battery, or many which have micro SD card support anymore. So, if the USB port goes, your screwed.
Wireless removes that one point of failure. Qi coil goes? You can still use the USB port to charge.
That being said, my wife's Mach-E has some real issues with wireless CarPlay at times, so I am really in no rush for it. I personally figure for short trips I just use Bluetooth. Long trips I plug it in. The charging over the Stinger's USB port isn't fast; it just needs to maintain and the wired Android Auto works fairly well, even though the stock Bluetooth interface is a bit easier to navigate while driving, and stock SiriusXM is much easier than the AA SiriusXM interface. But for longer trips or unfamiliar routes Google Maps is much better than the stock maps, so I plug it in.
