There is a big difference with this Koolatron model and the RoadPro copy. I've owned both. They're both priced identically and work good but in different ways. The RoadPro operates at a higher amp level so it will heat the food to a higher temp at a much faster rate. It can over-cook it too if left on too long. The RoadPro took about 30 minutes to make my  meatloaf, potatoes and peas super hot. The Koolatron needs about 1-1.5 hrs to get it to that same level of heat. The problem with the RoadPro is it will blow your fuses guaranteed. This happened to me three times with two different vehicles. This Koolatron takes a much longer time to heat up, almost too long. The problem with that is it will run down your battery if left plugged in for too long. This happened in my Ford F550 work truck after leaving it plugged in for about 6 hrs to heat up two different meals during my shift. We had to get a jump. That being said, I love both versions of them.
