Or a suitable generator? Daughter used my electric saw at an Arb show (to try to do some carving) via her 2kW genny and whilst it actually 'worked', it was nowhere near as useable as her 'dime tip' carving saw (even if she had a suitable carving bar for the electric saw it was much heavier and bulky than her Stihl carving saw and the cable *did* keep getting in the way and hung up on stuff, potentially leading to some very dangerous situations).
I'd probably agree with that, however, if it went wrong (oil pump etc), I'm not sure how easy it would be to fix / get spares for (if you were bothered to etc).
Daughter has looked at some the latest battery powered kit and if money wasn't an option, might have a small battery saw and possibly a battery strimmer, for 'tidying up' rather than all day use.

p.s. You can do some axe felling practice here: ;-)
