I'll share my experience, for the first 15 months I used a magnetic USB connector very simple to pop on and off.
Solid connection worked perfectly with android auto.
My Galaxy S10 would charge very fast even while using android auto, between 1-1.5% per minute.
This summer I decided to try the wireless charger for a while, It was very finicky so I changed to a cheap slim phone case, now its pretty easy to get the charger to connect, every once in a while I'll need to shift it a little no big deal. This does charge slow but it will charge to 100% while using android auto, between .5-.9% per minute.
FYI - I'm using the wireless Android Auto adapter by Motorola now.
It tucks away very nicely like it was made for the Ram, It connects quickly and reliably.
Most functions work quickly and seamlessly EXCEPT voice to text will initiate quickly but it frequently doesn't hear my message....
