For home use, I could see that working. On a building site, many machines may be used that don't have a cordless equivalent. Cement mixers, table saws, tampers etc.
With yard equipment, the cord gets in the way. I have a plug-in Stihl chainsaw. It is more powerful than my E-go cordless saw, but I haven't used it since February. My corded pole saw is mostly used to release the cordless one, when the bar gets pinched.
Batteries are brand specific. I have 4 E-go tools. Each came with a battery and charger. I put more miles on these, than on all of my other tools combined. The hedge cutter paid for itself again on the 4 hour
project in my last post.
My Stihl battery fits two of my tools and half a dozen others that I'd like to have.
My Makita batteries (5) fit my climbing saw, reciprocating saw, full sized 7 1/4 circular saw, radio and several drills. There are a hundred more items tthat use the Makita batteries.
The death of one tool, battery or charger, doesn't render other items useless. I keep my eyes open at yard sales, for stray equipment. Paid $10 for a Makita drill and battery without a charger.
There are a few other brands of cordless equipment that I consider worth owning. Husqvarna, Greenworks and Rigid carry a wide enough variety, for the interchangeable nature to work out.
Already today, I have made about 30 cuts with the Stihl pole saw, dozens with the Makita climbing saw and hundreds with the E-go saw. Cords would slow me down immensely. I might be able to get a third of my current production. Without batteries, the whole enterprise would not be economic and I would have to return to burning
gasoline.
