If you plan to have the tablet screen on 24/7, you probably won't be able to pull enough juice to keep it fully charged. The one downside would be the charging speed. With Qi, I also have the benefit of pulling the tablet right off the wall without needing to deal with unplugging it or plugging it back in. I'm planning on going this route because I dont think I really want recessed electrical outlet. Directly behind the tablet on the wall, I'll have a Qi charging pad.

My setup is a little different, as I plan to install an outlet in the attic and just utilize the existing security system wiring.essentially converting it to a USB charging cable. Personally, I plan on using a QI charging receiver, like this. Depending on the thickness of the wood frame, you should have plenty of room to hide the cable directly behind the tablet.

Great question and either option will work.
