Recommend an android tablet with REAR usb charging port?

[AC Question]

Hi everyone, I'm looking to get a cheap android tablet to mount on the wall for my home automation. It's just a touch screen controller so cheaper is good like the ones on Amazon. Was wondering if anyone could recommend one though that has the USB charger port on the BACK so that I can wall mount it without having the cable showing since most seem to have the charging port on the side or bottom. I've tried googling but can't really find a lot if any.
