It has a few video options, but the analog audio output only works in component and composite video modes.
There is an option to automatically start playback at power up, making it ideal for Halloween or Christmas video loops.

I’d throw it away and replace with a better quality 5V 2A unit.
The power input is 5V DC.
A quick demo of the looping. The screen doesn’t go blank, but does pause for a fraction of a second as it restarts.
