Keep food, drinks, and snacks ice cold or frozen with this 40L Black Cooler Box from Outsunny, whether you're spending the day at the beach, going camping with friends, or enjoying a nice picnic outside. The 12V fridge for the campervan can be plugged in and taken with you wherever you go to maintain an ice cold down to -20°C. Equipped with an LED panel, it allows you to adjust the temperature range at any time, and you can choose the max mode for fast cooling or ECO mode for energy saving. And its average energy consumption is only 60W! Also equipped with 110-240V AC and 12-24V DC adapters, which can be used independently or in the car. When the measured DC voltage is below the cut-off value, the compressor fridge will shut off to prevent battery depletion!
