    i have a 80 ltr 25yr old trailblazer that never ever had issues except that it wont fit into the patrol because of the drawers and i now use a 40ltr companion mamoth, never had problems and on -2 the beer is very cold and water bottles will freeze, it also lives in the back of the patrol like roofy's with a solar backup.

    Bit of a mixed question there but the Waeco's esp the early ones were notorious for being to sensitive to voltage when on battery.
    They would cut out at stupidly high voltages but that isn't the problem you saw.
    It was just too darn hot
    Probably the biggest advantage of the Engels over the Danfoss type fridges, in that the Sawafuji use less power in the first place and run at lower voltages.

    Voltage drop is a two part thing.
    One the manuf like to tell you it is there to save your battery which is kinda true but only because they need it more than your battery does.
    Part two is that the fridge needs the same amount of electrical power to operate and power (watts) is volts times amps.
    As the volts drop the amps rise and the the higher the current flow the more the wiring and components heat up.
    The more the wiring heats up the more voltage drop you get so it is a vicious circle.

    The Waeco 80 specs indicate they won't perform at 100% in temps above low 30's even if you plug them into the local power station.
    They aren't engineered to be able to do it but in fairness that would mean an ability to drop the temp more than 50 degrees below ambient
    Engel claim from 45 up to 55 degrees depending on model.

    National Luna are the absolute top of the wozza for fridge performance with a claimed ability to maintain -18 at an ambient of 43.
    Given their reputation and the field reviews I have read I believe them.
    Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.

    I fitted a 12v computer fan to my Engel. the later models with this mod were called turboed.
    I believe my fridge runs better ,,as in more efficient.
    Thinking about changing it again to more of a blower style fan.
    OH the fan is directed on the compressor, and cycles with the motor

    ROFL... sorry mate, good idea and does help but I just had a vision flash thru my feeble brain of a dual VNT Engel set up to run at -60 in the middle of the Marble Bar Car Park

    Slab of beer and a bag of servo ice was in there. Ice was melting at an alarming rate that day.

    He's over it and using the wife's 60 litre. I don't think she's getting that fridge back.
