I am using the charging block that came with the Fire tablet. I purchased a USB cable with a right angle connector for the tablet. The charging block is plugged into the controlled outlet of the Eaton RF9605 duplex outlet. Here are a few more pictures showing the cable and final installation.
This is the previous generation Fire tablet. VidaMount is not going to make a wall mount for the 2021 Fire HD10. I spoke to one of their sales staff. He said there isn’t enough interest to justify the cost of tooling up for it. Most of their sales are to businesses, and they usually choose one of the other Android tablets. He did say he knew some customers had purchased the existing wall mount and made the minor modifications (cuts and fills) to allow it to hold a 2021 tablet. I have one I am going to do that to for another location in my house. If you are interested, feel handy, and find one of the wall mounts for sale snap it up and have fun. They are probably hard (impossible?) to find now. VidaMount was blowing them out a few months ago.
EDIT: Notice the modification I made to the wall plate around the brushes so the cord can lay flatter.
