1.5 hours runtime for like half a liter of gasoline?? That’s unbelievably inefficient. A half-liter of gasoline is like 15MJ, should power a laptop drawing 30W for a week.
30W is 0.04 HP. That engine is just way, way bigger than you’d use if you were designing something like this from scratch, I think. Like putting a truck engine in a go kart, and being surprised that uses a lot of gas.
One of my friends is homeless, living out of his RV. Rather than going to the library or some other third space to charge his phone, he runs his generator. Then complains about running out of gas.

Maybe it would be better with a fuel cell.

anything but metric :/
I like metric fine, I just figure US audience is more familiar with small engine HP.
I don’t think that little generator cares if anything is drawing power, it will just output what it outputs full time
