Are you trying to get it cold from hot in the Jeep? It’s a lot of draw if so. I always left my fridge in the Jeep and if it was off I just plugged it into house power, got it cold then switched it over and never had any issues. When I got my second one I would just cool it and fill it in the house and then load it in whatever Jeep I was taking.
