So I figured out a basic task that does what I need.
If the tablet doesn't have power for 10+ seconds it triggers an audible alarm and the wallpaper turns red.
This doesn't change until fix the power or it dies, whichever comes first :)
10 seconds is short for most people but this is a tablet that should be connected to power 24/7 since it's a bedside tablet and alarm clock.
