I agree, but the OP's question was rather vague and the followup
answers wandered all over the place as well.

Just to throw some more sh*t in the game, the first time a human
hooked an animal to any device that performed some sort of work on
behalf of said human could probably be said to be a power tool driven
by other than the user's hand power.

OP specifically excluded tools using animal power (which
presumably also includes human power).

There's a bit of a fuzzyness there, tho, if you consider
stored power. If an animal compresses a spring, or carries
water to an elevated tank, and that is then later used to
power a tool is it still animal powered?
