All of our current fridge models (Classic I and II, Elements, and ZERO) use the same power cords.
The AC cord is not available through ARB, it is a standard small appliance cord that is used on TVs, Computers, Monitors, etc. (NEMA 5-15P to IEC-320-C13)
The DC cord is part number 10910076:
Also available is our Fridge Wiring Kit, part number 10900027. This is wired to the battery and provides a socket for the DC cord.
