If given these as the only options, I'd beat my coffee into chunks with a hammer before using pre-ground.

the only thing that would be good for is french press. i dont think it grinds any finer.
A hand grinder would be much quieter (zassenhaus, Hario). But if you're grinding for a pot, that could be a workout.
