I saw one of these on a post here and I ordered one. It is so quite a couple of times I had to put my hand in to see if it was running. It sprays out a mist which cools as well as aerates the water. It runs off a 6 volt lantern battery or you can get a 12 volt converter which plugs into your boat(which is what I did) It draws very little current. If I was going to use the 6 volt applcation I think I would get a rechargeable small one, even though it will run a long time on the dry cell.

I have a cigarette lighter plug on mine for the boat, so if I am carrying them in the car, I just plug it into the lighter plug in the car. My car has an outlet in the cargo area which is handy,
