What level of cooling performance can we expect from a Koolatron cooler?
40 to 45 Fahrenheit (22 to 25 Celsius) degrees lower than the temperature of the surrounding air. It is best to load pre-cooled food or drinks into the cooler. As a rule of thumb, it takes about one hour per pound of material loaded into the cooler to bring it from room temperature down to maximum cold. At a temperature of 80 deg. F (27 deg. C.) the contents of the cooler can be maintained at approximately 38 deg. F (3 deg. C) (Normal household refrigerators are usually maintained at 45 to 48 deg. F. (7 to 9 deg. C). At a temperature of 90 deg. F (32 deg. C.) the contents of the cooler can be maintained at approximately 48 deg. F (9 deg. C).
