Pros Largest temperature range, good insulation, lightweight, few moving parts, can be used as a chest or standing upExcellent temperature control, energy efficient, large capacity, extremely sturdy, full of useful featuresEnergy efficient, good features, super durable, long DC cordExcellent low energy mode, long cord, good temperature range and control, useful baskets, less expensiveVery energy efficient, relatively inexpensive, impressive minimum temperature, surprisingly lightweight, long cord
Cons No AC cord included, not the most durable, energy hogExpensive, relatively short cords, no energy-saving modeUnimpressive minimum temperature, heavy for its size, relatively loudHeavy, small capacity, control panel on backNot durable, takes a long time to cool, insulation not great, fairly loud
Bottom Line The best temperature control from a thermoelectric coolerControl, efficiency, and ruggedness built to last the yearsSuper durable and energy efficient, though a bit loud and with no subzero tempsA pretty good, albeit heavy, cooler for lessSpend less on this solid performing cooler
