As regards "Pay attention to how much fuel you have" would require having some way to check fuel level ... there is no fuel gauge on the Champion nor the Honda. There is on the Yamaha. In any case, adding fuel to a running generator is a real good way to fire, explosion, and/or death.

As regards "how would the generator do a “smart shutdown”?" ... It does not seem difficult for any manufacturer to implement a fuel level sensor, and when the sensor detects "Low Fuel" a relay disconnects the power, and then shuts down the generator. !!!!

I can't believe these engineers haven't thought of that, and how that easily accomplished feature would be a sales boon. I think I will write to Champion, Honda, and Yamaha.............

Your understanding of how equipment works is lacking. The very act of the generator shutting down while equipment is powered on is what has the potential for damage. Whether because it runs out of fuel or a sensor tells it it’s about to run out of fuel and it chooses to shut down, the result is the same. A low fuel sensor wouldn’t help in the least. The device needs to be shut down while the generator is running to eliminate a chance for damage. That is not only not simple, it’s not possible without extensive redesign of the equipment being powered by the generator.
