Why won’t my Champion C46540 generator run the microwave?

It was mentioned the 3 wire RV outlet could power both 120v legs with an adapter. What is this adapter? Sounds like this will provide more wattage.

My microwave is an inverter style, or at least says so on the front. I’ll lug it out to the 46540 tomorrow and hook up to the RV outlet (i have a pigtail to 2 120v outlets in a box) and see if it has same issues. I suspect it will run better.
