Does this have enough output and a suitable tone to be used by an ice hockey referee? Will probably need to wear a mask getting back on the ice soon

Possibly depends on the size of the arena and the size of the crowd.

Is this loud enough to keep coyotes away?

It's loud enough to get 200 student's attention in for recess so it's probably loud enough to keep a coyote away.

Could I use this to ref a soccer game?

Yes, definitely loud for games.

Does it come with a charger?

I don’t know. But there is a port that looks like a charger would ply into it to recharge. I have been using this whistle for over a year now and haven’t needed to recharge it. There is a large battery in it like a 3” long AA battery; not your typical battery. Sooty this doesn’t completely answer the question.
