I needed a mount for my old iPad 7th gen. Some models are out there but they were not fitting my needs. So i made my own.
It include a wide enough outlet for a magnetic plug to charge the tablet.
I'm using this charging cable: https://www.amazon.de/dp/B0C6LJXVPH
The wall mount allows to slide in the iPad and if the mangetic cable is positioned at the right spot, it will catch and charge.
If you want to use the tablet mobile instead directly on the wall, you can slide it of the mount and do your thing.
