Hi,
I mounted a Amazon tablet beside the light switch, thought might be a good idea getting a mini adapter hide in wall to power the tablet. The setup does look okay but now I worried about potential fire and safety hazard…
Are those cheap AC-DC converter safe enough to be hidden inside the wall? Is it a good idea to wrap this adapter using electric tape?
Thank you in advance for all the advice!

I’d throw that in the bin. The AC terminals are so close to the USB socket, there’s no way that’s not a death trap.
The little PCB through-holes just below the metal case of the USB socket are the LIVE (er…hot, I think you call it) and neutral connections!
Yes, it’s “only” 110V, but if that finds its way to the tablet things will end badly.
I agree with @Troon, I would not put that in my wall. Wrapping with electrical tape might actually make it worse since it will reduce the heat dissipation.
You do have a few options that you may not have thought of:
You have ~24Vac (probably 19Vac) right above in you doorbell chime. You could rectify and reduce to 5V.
Mount a recessed outlet with built-in USB ports (UL listed of course…or equivalent)
