I really meant when your state has rolling blackouts from not being able to supply electricity to everyone. Then you will be in no better shape than those that can’t use a gas powered mower.
I don’t buy things looking at me being better off or worse off whether I can get something gas or cordless. I’m a light tool user and in terms of maintenance and convenience, I gradually replaced my gas tools with cordless. Not everyone can do that because they have different needs and circumstances than I have. My buddy has a slew of nice Stihl chainsaws and he needs those for what he has to take care of. To me its more sizing up needs and picking the best tools to meet the needs.
