The Powerbox® Plus 36L thermoelectric cooler features 30% more insulation than its predecessors. Food and drinks stay 20°C below the outside temperature, regardless of the power source used. The improved fan is extremely quiet, providing comfort during use. The cooler is antimicrobial, reducing the growth of odors, fungi, and mold, and this protection is permanent. The new and modern design, along with the thick polypropylene shell, ensures it stays cold for hours even when not in use.
