The Igloo Cool Chill cools without ice – just plug into your vehicle cigarette lighter or other 12V outlet. This popular size thermoelectric cooler is ideal for use in the car or truck while traveling, or dorm rooms or offices when used with a compatible AC converter (converter not included). The cooler cools down to 40 degrees Fahrenheit below the outside temperature. It features a brushless motor and convection cooling so everything stays cold, not just some of the items. To top it off, it can be used either upright as a refrigerator or horizontal like an ice chest!
