I'm no expert by any means but i do research a subject i have an interest in.Realising you are something of an expert, I hesitate to question you but surely a cheap genny (no inverter) will always produce a pure sine wave as it is coming direct from a mainbs voltage alternator. You will only get a square wave from a cheap inverter.
Incidentally as I found by experiment, a cheap 500w inverter (modified square wave) runs the motors in the little twin tub washing machine with no problems, and a bigger one will quite happily run a hairdryer, so not necessary to have a pure sine wave for all motors.
I agree it is the mains spikes that may damage the van charger using a cheap genny, but not because they produce a square wave.

a cheap (non-inverter) or site genny will only produce a square wave form,

Until i find reliable proof otherwise i stand corrected Brian.Sorry John but I'll believe it if you can show me proof. I can bring a battery scope to a meet if you like.
I think you are confusing inverters here.
I believe el cheapo generator will produce a sine wave but frequency and voltage will be very variable which is highly undesirable for electronic equipment.
I also believe that the so called pure sine wave inverters or gennies are a lie and are in reality a digitally synthesised sine way close to a pure sine wave. I've got a good "pure sine wave" 300W inverter, I'll scope it tomorrow and report.
Until i find reliable proof otherwise i stand corrected Brian.
first picture is from a cheap non-inverter genny...still a very rough waveform
second is from a Honda inverter 2kv.
third is from a cheaper inverter genny

just out of interest could you scope the mains coming into your house as a bench mark

" Theoretically any rotating generator describes a sine wave and the output of the generator should be roughly sinusoidal allowing for manufacturing defects or inconsistent materials."
I'll scope my inverter tomorrow, try and find some nasty loads for it.
