The Silent Type | Foldable Handheld, Neck & Desk Fan, 5 Speeds, LED Display, 13-Hour Battery

It folds down to nothing and opens into whatever you need — held, worn at the neck, standing on the desk while you work. Five speeds, and even the loudest of them stays under the conversation. That is the entire point of it. Thirteen hours, tracked on the display, so the battery is never something you have to think about. The woman two seats over keeps glancing at it, because she can see it moving and cannot hear a thing. Quiet is the expensive version of everything. Loud is what you buy when you could not afford discreet.
