We lost power for several days during the Palisades Fire, I had a Honda 2200 gas generator on my fridge. When I plugged and used a microwave I could hear the generator struggle and then the microwave shut down after running a short while. The microwave initially was dead but after a few attempts would run but the LED faceplate and control panel was shot, only the 1 minute timer button worked. Of course it was a built in and not easy to replace.
Probably not a good thing to have on your audio line.
