Today i test my new generator that I bought from bunnings and I couldn't be happier. $400 for a 700 watt kipor that ran both my fridges or freezers as well as my 8 amp battery charger. It is only suppose to use 1.5 litres /3hours of moderate use. It was fairly quiet, at 25 metres, I had trouble hearing it.
My problem now is where to fit not only the generator in the car but where to put the fuel, oil etc for it.
