The MT35W is an iceless thermoelectric cooler that lets you cool the air to a maximum of 34° F below outside temperature or warms the air to 43° F above the outside temp. Cold drinks or queso, whatever you and your family or friends need the MT35W can handle. Multiple power options allow you to pack up at home (AC), get to your preferred temperature, unplug, plug back into your vehicle's 12V (DC), and head out for the day. At your destination, just roll the MT35W to the perfect gathering spot. Extra-thick insulation keeps contents at the right temp, and lightweight design with built-in wheels and a dolly/carry handle let you roll with ease. Just plug back in for the ride home.
