Product review (5 stars): Cools from House, Car and Hotel
Planning a car trip and wanted to save time and money by bringing breakfast foods to the hotel.  As it turns out, the hotel didn't provide refrigerators in the room so this product solved everything.  Took it for a shorter test run and this is what I found: I plugged it in while in the house with the AC cord and let it run silently for a short while to get cool. I didn't notice it getting very cool so I was a bit skeptical.  I loaded some food items and wheeled it to the car where I plugged it into the back of the car DC outlet hoping for the best. At the end of the 3 1/2 hour car ride (New England Summer), the cooler and food were nice and cold. I am VERY pleased with the performance of this product and would highly recommended this to anyone who travels.
