The Road Trip's extra-large capacity keeps food cold with a lot less effort than traditional coolers, as it lowers the interior temperature to 40° below its outside surroundings. It transitions from vertical to horizontal for use at home or in a vehicle. Adjustable doors open to the right or left, and molded handles make for easy carry. Plugged in, the unit is so quiet you'll hardly know it's running. It's not only great for tailgating or transporting food to your campsite, but also ideal for the office or dorm room. 12-volt DC power only; 110/12-volt inverter needed for indoor 110-AC power use. Made in USA.
