Microwave / inverter combo
For what it is worth, my gimballing microwave also can be used underway with the inverter. Very handy, at times, although I more often use it at anchor or the dock. Yes, I have a large battery bank, and yes, I try to time it with engine use. An example would be nuking the morning oatmeal while upping anchor, or baking the evening potato while lowering and setting the anchor. It is also handy for those times you absolutely have to motor, and it is very hot, and the cabin would be more than toasty with a regular stove or oven.
