This is my second Go Power 1750hd inverter. My first lasted 7 years on our winter trips on our 36ft saddle bike. When I received it last month I was surprised to see how much lighter and smaller it is. I replaced it and checked it out after 10 minutes. Very quietly, a cup of water heated in the microwave, the woman turned on the vacuum cleaner. We usually use our inverter when we are in dry storage and want to watch a movie from TV and PVR to charge our phone and 110v lights.
