Just want to say thank you! Cooler output is around 36 degrees cooler. Used it in my mail truck yesterday. I have to get out and load mail at each stop but it made it bearable for me yesterday being out all day in 118 degree heat. Every time I jumped in the truck to head to the next stop I was able to cool off with cold air blowing right at my face. Made a huge difference and couldn’t be happier. I have to throw a separate cooler Behind my seat for fluids which is not a big deal. Since it was not running constantly all day it only went through 2- 10 pound blocks of ice. Used it from 10:30am when I left the post office to 5pm when I returned. Maybe eventually I can upgrade to a blow box. It would be fun to build one.
