we ought to use my chainsaw to save wearing his out (typical), so we
did. Unfortunately my chainsaw (Bosch 1750W) suddenly stopped working.
All it did was emit a loud buzz and some magic smoke. Not to worry;
I've had it for at least twenty years and it had done a lot of work,
and the oiler didn't work and the chain tensioner only just worked.
(Later I dismantled it out of curiosity and found that the front motor
bearing had seized absolutely solid. But surprisingly the gear wheels
showed very little wear and the motor brushes were still quite good.)
I don't know whether to get a petrol or electric chain saw. If
electric a constraint is that I want it to work from the genny, which
is 2kW. The bigger chainsaws are 2.5kW.

Here, a gentleman in the video, measures an electric chainsaw.
With the chain not moving, the peak input current is 50A on the
120V powered saw. The normal operating current is more likely
to be in the 15A range. That's at least a 3X multiplier.

Many power tools have a soft start from EU regulations.

Generator MCBs should be tolerant of short term transients.

Most of the time you will get away with the start current from power tools.
