I've got one in my RAV4. When you turn on the cooler, it diverts cold air from the airconditioning into the space and will keep a drink cold on a hot day.
My glove compartment is supposed to be a cool one. Not that I have much use for that but for some reason I did recall it performed this function the other day, when I'd bought a small bag of fancy chocolates for someone's birthday.
Unfortunately my mind is going at my age. I parked outside my house and left the gift safe in the nice cool box, and wondered why they had melted together when I got back to them some hours later on that hot day.
