Depends on how much power you need at home. I have a 2000W Honda that does what I need for camping. I could use it if the power went out to run the fridge and my pellet stove at the same time. Gotta remember to have ample gas to run the gen when the power goes out as gas stations won't be open either. As a rule we never lose power but maybe once in 10-15 yrs. And it only lasted last time about 3-4 hrs.
