Underpowered USB for Fire TV Stick topic

My Fire TV stick acts up when powered from the TV usb. It works fine from the AC adapter but I'd rather use the USB because it is less clutter. Will something like this solve my issue?:

I want to do a full backup of my original ROM. But I believe I need to root to do that.

Now if I root it to back it up, if I restore the ROM, will it still be rooted?
