I have used this one and it works pretty well. DOOBDI Wireless Car charger
Got it for my Fold 3 and now my Fold 4 in the open position. The good thing is my son can put his iPhone in it in landscape and it works too.
You need to have a good quality and high AMP power port.
I used this one to vent mount my Fold 3 in my Kia Optima and it was great. I don't currently use a mount in my Palisade because I switched to the Carlinkit AI which gives me wireless android auto and an android os on the touchscreen. But I think the mount should work just fine. I had the spen case from Samsung for the Fold 3 where the pen was mounted on the hinge and it fit and charged just fine. With the new case and the placement of the pen on the back, you will probably need to remove the pen in order to have it mount and charge. Don't listen to the people asking why mount. They don't understand how awesome that unfolded screen is in the car, much more versatile than AA.

I personally use this mount and it is amazing. can have the phone in a case, and open or closed it all works. plus it charges and leaves room to run a cable in dock mod if you use android auto. https://www.amazon.com/dp/B08LBJ8LDK?ref_=cm_sw_r_cp_ud_dp_WH4GKVW0VTCJ14MCBFC9
