I use my 2KW generator for the short time needs for the microwave and the Cuisinart Grind and Brew coffee maker.
I have a 600WATT PSW Inverter running 120VAC lights, HDTV, and other low wattage items.. I run two drop cords with multitap heads from the 600Watt Inverter with one drop cord on each end of the POPUP trailer...
I also have a multiple battery bank setup and the main reason for the 2KW generator is to recharge my 50% depleted battery bank each morning when allowed back to their 90% charge state. This allows me to use the batteries again for the next day/night run off the batteries... This takes around three hours of generator run time...
Keeping it simple was best way out for me....
