As it happens I bought a Lidl electric pole saw a few weeks ago. It has it's limitations and is slow compared to my stihl pole saw but in reality it gets the job done before I've started the stihl and there's no need to leave it ticking over between tugging branches out of the way.
If I was in the market for a new hand chainsaw then it's be electric for the same reasons.
I'd also take issue with statements like 'It's good for a 4" tree'. I had a huge oak fall over off the bank into the drive a few years ago. It was hung up on it's own branches and a potential danger to anyone close cutting. I sectioned it with the stihl pole saw and that has quite a short blade. Yes it took a while cutting wedges out and working from both sides but it got the job done safely. I do have a saw with a 30" bar so it wasn't a case of no options.
I was taking down a tall slim ash tree today with a 10" trunk. I'd have done that with my lidl petrol jobbie but the bloody thing has started throwing the chain and after putting it back for the third time (I think it's stretched beyond tensioning) I had to get the big boy out. I'm sure it's heavier now than it was when i bought it 6yrs ago
- I almost used the electric pole saw for that except the battery needed recharging and I was getting pigged off with all the delays - clearing brambles for access, roping it to direct it away from overhead wires and so-forth.
