I have all electric lawn equipment as well, though my mower is a Toro. No disagreements that a 13A blower connected to AC will beat the shit out of a battery-powered leaf blower, but I'm sure you do and hopefully did realize that, the math just doesn't work out. The one place the Ego does excel at is stuff like edging and string trimming, where there's not nearly as much power needed. They definitely struggle a bit on things like chainsaws and blowers where more power is just generally better.

The place where it is weakest is probably snow blowing. They now have a 2-stage electric blower, but I am pretty sure it's just nowhere near gas. I live in the midwest in an area where the 1-stage Ego electric blower is already kind of overkill, so that's what I'm running. It has its negatives and positives: it always starts without having to worry about the fuel sitting over the seasons, it's quiet during operation and doesn't pollute, the batteries are always ready since they are on the charge when not in use, and I have enough battery to run it for much longer than needed. That said: the batteries are, indeed, simply too expensive.

I'm surprised the mower sucks, this Toro electric mower feels reasonable compared to anything else I've ever used (granted, I do not have much lawn and have never used any serious mowers. Just your average lawn mowers). I wonder if it's true that all electric mowers suck or maybe it's just that Ego isn't/wasn't doing a good job on mower design.
