Yesterday I went to my daughter's with a load of wood. I was rewarded

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.

If you are after new - take a look at Ego cordless ... with massive 56V
power packs they offer a lot of cutting time
https://egopowerplus.co.uk/products/chainsaws


This is how they get their snowblower battery pack, onto the chainsaw.
Via belt you wear, and a cord. That's the 7.5Ah pack. Those packs
cost as much or more than a chainsaw. Even the charger for the 7.5Ah
pack is expensive (maybe 1/3rd the price of the battery pack).

There's an example of the pack here. Cells exposed at 2:34.
