I see that it says the output relays are different size. One is a 16 amp and one is an 8 amp. I will be running two mini-fridges and want to make sure I can cool them both with this controller. I'm pretty much just planning for the future when I need to cool two at once and figured if I could just get one controller I would be better off/cheaper. I also may get a chest freezer instead of the second fridge so I need to be able to handle the power. Anyone run into this?
