Actually none of them do... As they don't have a compressor they have no "Pull Down" ability. They will always be exactly the number of degrees below the ambient temperature as per the manufacturer specs.
So lets say they do 42 Degree drop max. So if it was 80 inside the car it will be 38 in the cooler (close to a fridge)... Cool. If it is 105 in the car the cooler will be 63 in the cooler, not cool and things WILL start to go bad at that temperature if you have meats in there. (Typically most 12V Coolers cannot attain the 42 degree drop in hot temperatures or even close)
Portable coolers only work when the air conditioning in the car will keep the ambient temperature of the vehicle in an acceptible range. Check with
