A:Answer The P75 cooler draws approximately 4.5 amps (50 to 60 watts) When your vehicle is running and the electrical system is operating properly, your cooler will operate continuously without discharging the battery. When the battery is not being charged, the cooler should not be operated from more than 4 hours. The cooler can be operated continuously from a 110/120 volt AC wall outlet using the optional Koolatron AC Power Pack.
