Q:"Can you set this cooler to a certain temperature?" Kip
Answer: No, there is no temperature setting on the Koolatron Voyager and other non-commercial Koolatron cooler units. These units cool 45 to 50 Fahrenheit degrees below the ambient temperature. "Ambient temperature is defined as "the temperature of the medium surrounding an object or. . . the prevailing room temperature." So if it is 90 degrees in your car, the temperature of the cooler will be 40 to 45 degrees F. We do suggest you pre-cool the unit using an AC adapter. This unit also can serve as a warmer to keep food warm for a picnic or other event where food will be consumed within 45 minutes or so.
If you have need for a commercial cooler, please contact us with your requirements and we can get a price for you dependent upon the size of the unit.
