That seems like a somewhat orthogonal point? Like, if I'm a carpenter and my batteries all run out / I can't actually power my power tools then the best course of action is to go home and recharge all the batteries instead of trying to hand-cut 100 pieces of lumber today. After all, the power tools can do it a lot faster (and with less effort) than I can.

I say this as someone who's watched a bunch of woodworking videos but hasn't actually done this myself :)

I read that more so as, I'm a carpenter and my batteries have all ran flat, so I'll put them on charge and do something else today. I'll cut up the lumber tomorrow when the batteries have charged.
