The 18V X2 LXT® Cooler/Warmer Box is ideal for use on the job site or on the road. The cooler has four cooling modes capable of holding constant temperatures of 15°F, 30°F, 40°F, and 50°F, while also having two warming modes capable of 130°F and 140°F. It operates using one 18V LXT® battery with the option to insert one additional battery for extended run time (batteries not included). It can also operate from a 12V/24V vehicle plug, or corded AC power. There is a large, easy-to-read L.ED. display allows you to check the temperature and remaining battery time. For added convenience, it has a USB charging port to provide power to common devices like phones and tablets.
