Questions - using a 120v power inverter (1000W)

I doubt that a 600-watt blender would work with a 1000-watt inverter. Electric motors require a large inrush of power to start -- depending on the design of the motor that inrush would be two to three times the rated wattage. Inverters are best suited to steady loads, like computer power supplies, charging cell phones, lunch box oven, etc. The most important thing for any inverter installation is to use suitably heavy wire from the battery to the inverter. In my own installation of a 750-watt inverter I mounted it right next to the battery with No. 4 stranded copper. An extension cord moves the 110-volt power to the cabin of the car where I use the power to make coffee (Keurig single cup coffee maker), heat soup (300-watt 3 cup crock pot), rice cooker (Wolfgang Puck 3 cup). I also charge cordless batteries for tools, run a drill, etc.

I last left off wanting to modify the device or really, better, the inverter with a soft or hard start capacitor. Never completed that project... though was on my mind with a 1200W inverter for the chainsaw (9A) and 1000W hotplate running a dedicated deep cycle battery that was charged by the 12V outlet with a charger. Thought for circular saws also would be handy.
