They cost a lot more money, but inverter microwaves use less power.
not really. I have a regular one in the house and a panasonic inverter in each of my trailers. Physics and electronics determines power draw. For the same output power, line draw is virtually the same. Total power draw likely varies between different units, but not enough to really care about.
Now the inverter units when running at less than 100% output will draw less peak power than non inverter, total watt-hours likely remains pretty much the same. The inverter units power draw at less than 100% is pretty linear decrease between 100% and about 20%. Below 20% it is non linear partially due to the overhead draw for control.
Now there are THREE advantages (at least) to the inverter microwaves from panasonic.
1) for power settings below 100% power doesn't cycle between 0% and 100% so if running of a generator you don't have the generator cycling up and down
2) I've found the constant X% power for defrosting, warming etc. to do a better job than the cycling power units
3) I can run my 1200W inverter microwave off my 1000VA true sine inverter. At 50% power setting it draws about 800VA and runs nicely off the inverter. And at 50% power it doesn't take twice as long as 100% to reheat something. Don't need to fire up the generator to run the microwave for a few minutes to heat something.
And to the OP question. I've run "home" microwaves in both my trailers since 2004. They work fine as long as you get one that can fit in the spot. And they are lower cost.
