    Similar question to SMB, we have has the dometic freshlight air conditioner installed for our jaunts down south (plus wishful thinking for uk!)
    The blurb say " The air conditioner has 2100-watt cooling capacity for 230-volt stationary operation"
    But then Technical Data:
    Cooling capacity (kW) 2.2
    Capacity (BTU/h) 7500
    Power (V/Hz) 230 / 50
    Consumption, cooling mode (W) 950
    Consumption, heating mode (W) 1200

    And apparently low energy start up.
    Lights are all LED, fridge/ freezer AES, TV is 12v

    How many amps do I in theory need please

    About 50amps at 12v

    About 4 at 230

    Cooling mode 950/230 = 4.13A
    Heating mode 1200/230 = 5.22A

    It's a heat pump (like all fridges / decent aircon units) so the power is used to shift heat from one place to another rather than providing heating or cooling directly. Hence the output in Watts is higher than the input.

    Reading your post again i think you were asking about the van in total. I would think 7amps @230volts.

    Or to be on the safe side, you might consider towing a medium sized generator. :Smile:
