This large 42L cooler features dual thermoelectric/compression cooling technology to maintain the cold chain and keep your food and drinks fresh. Connected to 230V, you use compression technology for cooling down to -12°C. When you switch to 12V, the thermoelectric technology that cools down to 15°C below the ambient temperature allows you to maintain the cold during travel time or in temperate weather conditions. With integrated handles on both sides, its robust metal and plastic design make it easy to carry and transport. Reinforced insulation with triple wall insulation (metal, polypropylene, and polyurethane foam) and a lid with an integral rubber seal to eliminate heat loss.
