back in the days of lots of power failures I only had a 1000K Honda. I used it to run one refrig, then the freezer. all the while I had my pellet stove running. the little honda never grunted or complained once. I have since retired it to my son and I bought a 2000ui, hardest starting gen set I have ever seen. but when running it runs great. one reason I went to bigger gen is I no longer have the pellet stove and now we run a few 1500w heaters and no problems with them either.
