Is this compatible with the Galaxy Watch Active?

This watch charger is specifically designed for Samsung Galaxy Watch R800/R810/R815 42mm/46mm ONLY, do not work for galaxy watch active, please kindly note.

Will the charger stop when battery is full? Is it safe to leave the watch on it, over night?

I dont think it does. I would hear my watch vibrating throughout the night and flashing 100%. So Im.assuming it was still trying to charge the watch. I don't like this charger

Why will my charger not charge past 0 it’s been like that for an hour and my charger just arrived today :(?

Jonathan, If your watch does not immediately start charging (We "are" talking about the Galaxy Watch - correct? As this is not designed to work with any other watch series), then there is something wrong with the charger. Send it back. It has been damaged in some way on it's trip to you. Amazon is great about replacing your unit or refunding your money. Don't even mess with it any longer. Just send it back and get another one. By-the-way, this charger is fantastic in how quickly it charges, as you will see when you get a fully operational unit. Hope this helps . . .

does this charger only have an usb cable or can it be plugged into electrical outlet

The "wireless charger dock" requires 5vDC. This is supplied by most standard USB chargers. You may be thinking that the charger has maybe, two prongs on it that plug directly into the wall ? . . . It does not. It (the wireless charger dock) requires "low" voltage, which is regulated by any commonly found USB charger. If you have an extra charger lying around, maybe one that you use to charge your phone (especially a Samsung phone charger), then check the label on the side or bottom to confirm that it outputs 5VDC. If it does - just plug it in and you are good to go! I hope this helps.
