Which electric chainsaw did you use?

I haven't used one, but I saw a youtube review from Project Farm. You can check it yourself. https://www.youtube.com/watch?v=u6FM_08066I

The DeWalt chainsaw was similar or better than Stihl, in a different series of tests, including cutting trough 10 inch logs.

There were other brands which would stall or be worse, so it depends on the brand.
