I can understand the coffee thing. I had our systems set to run the auto drip in the morning. run the microwave for up to 10 mins and use a vacuum and hair dryer too. We could even run a 400w window AC but other than the coffee maker, we had to remind ourselves that the rest was there. This year I may make the coffee on the stove and leave a lot of gear home.
One thing I can tell you is stay away from the cheap ebay PSW inverters. We had a 3000w Power jack that lasted one season. It ran everything just fine until I started the little AC, it did it once and that was that. Repairable? Probably. Worth repairing? NO
