5 thoughts on “Power Consumption of Household Appliances”

  1. I am wanting to use a Ryobi 1200W petrol generator to charge a Nissan Leaf 2013 and cannot find a Safety load to allow this to work.
    What do I need to add in to achieve Charging ?
    My intent is to have a Reserve Power Supply for very long trips between Superchargers !!!
    Yours in Faith
