You have got it totally wrong, 99.9% of generators are regulated, Otherwise how on earth would the manage to keep their voltage constant,
Like I said DON'T take my word for it, You have been warned, Don't come crying when your fridge bites the dust and that company who made it refuses to fix it under warranty or hands you a huge repair bill,
Also before starting or STOPPING a Generator the Fridge MUST be switched OFF and When using the 12v Supply from a Generator there MUST be a Battery of Equal Voltage between the Fridge and the Generator.
Those of you who own an ARB who are in Doubt Read Page 4 regarding using your fridge from a Battery while using a High Speed/Powerful battery Charger, , also to NOTE is Never run your fridge from a Battery Chargers or an AC to DC Converter or a rectifier and also read Page 13 of your Manual.
Of course there's
some regulation going on. You'll note I said "unregulated (or poorly regulated)" in my response. Ignoring that indicates some problems on the receiving end. You keep lumping all generators together, when there's a clear difference between what's commonly referred to as unregulated & regulated output.
Your dire predictions don't concern me. As for the rest, that's not the same discussion as your All-Generators-Kill topic.
I don't know why you don't recognize the difference between a generator that outputs well-regulated 120VAC and whatever approximation of 120VAC is produced by a Harbor Freight special. Maybe looking over
this gentleman's results will help.
Do you see a difference between the quality of the regulation between these two generators?
Which one do you think does a better job protecting sensitive devices?
Which one do you think costs more?
Here's another interesting photo.
That's the unregulated 12VDC output of the same generator that provided the graph in the first photo. Even within the same generator, there's a significant difference between regulated & unregulated output.
