iPad Pro Case This case charges the pen when it is in place no muss no fuss. On Amazon.
I had to do the same sort of thing with my MacBook Pro. Only two USB C ports. If you use one for the charger, that leaves one open port. Had to get an add on USB hub.
Like I said, the Macs are still good machines, but they used to be the go to machine for the creative. Now, they're more like jewelry.
