Yamaha generator review
Our new Yamaha
generator is quiet and efficient.
It runs for twelve hours on one tank of gas at a low load --- a few fans, a light or two, and a laptop charger.
The Instant Pot and circular saw work on the generator too, but both run at a slower speed. After the first test, Anna opted to continue cooking on the propane camp stove instead. I kept using my saw.

About us: Anna Hess and Mark Hamilton spent over a decade living self-sufficiently in the mountains of Virginia before moving north to start over from scratch in the foothills of Ohio. They've experimented with permaculture, no-till gardening, trailersteading, home-based microbusinesses and much more, writing about their adventures in both blogs and books.

A circular saw is not a purely resistive load. Such saws generally use so-called universal motors, which is basically a commutated series-wound motor. When running, these motors generate counter-EMF. The voltage and current are not in phase anymore and hence their power factor is reduced. Under such a load, the inverter-generator cannot deliver its full capacity. Check the manual.
For the instant-pot, the main power use is probably the heating element. When running at full blast, this is a purely resistive load. However, it is probably electronically controlled with I suspect pulse width modulation. That will probably also reduce the useful output of the generator.
