My electric cooler is 12v so it doesn't run off of the inverter. But I do have a small microwave, toaster and and blender I use it for. The boat also was originally wired with 120v lighting, which I've now replaced with
LED bulbs, so I can run that off of the inverter when not on shore power. Also, the occasional use of small power tools happens when I'm not on shore power and it has worked well for everything so far.
