Under ideal conditions, the cooler can run for several hours. However, other factors can potentially cause the battery to drain much faster – for example, if other accessories (phone, laptop) are plugged in at the same time. We recommend you leave the cooler plugged in for a maximum of 1-2 hours.
Mobicool W35 has a “battery saver” function, which prevents the car battery from being completely drained. The cooler switches off automatically, leaving enough power to start the car.
