A 2000 watt generator could power a 500 watt deep freezer and one element of the electric stove. Or you could run the freezer, cook with a 650 watt microwave (using 1000 watts) and a few lights. The typical electric range with 8” elements will use all 2000 watts if you use it while connected to the generator.How many watts does it take to run a house?Homeowners can often power most household appliances using between 3000 and 6500 watts.

If you have a larger furnace and/or a well pump, you will likely need a 5000 to 6500 watt generator.
