All true. The cigarette lighter plug method is doomed to failure. There is nothing wrong with the cooler electronics. The plug becomes loose and creates a relative high resistance. Resistance at that current draw equals heat. The more heated it becomes and the higher the resistance becomes in turn causing more heat until destruction. Classic thermal runaway. The best method is to hard wire and you will never have another problem.
IV=W like the ladies name Ivy Watts is the easiest to remember but it is also V2/R and I2R. All are wattage formulas. Resistance is the bogeyman. It applies to all electronic equipment.
Colemans do work but overall they are crap compared to the other 2 brands. The smaller Koolatron with the cooling unit in the lid is definitely a better cooler. I have taken 2 Colemans apart and rebuilt them and they are sloppily made.
Sidebar. How to repair a Coleman for nothing. Take a screwdriver and dead Coleman to Walmart then go inside and buy a Coleman. Take Coleman to your car and swap over the cooling unit. Box up the new one and return it to Walmart. Say it doesn't work. They will give you your money back on the spot as they couldn't care less.
