The Three-Room Summer | Set of 3 Rechargeable Handheld Fans, 3 Speeds, 180° Adjustable Head

Three of them, which means one never leaves your bag, one lives on the desk, and one belongs to whichever room you are holding court in. The head tilts through a hundred and eighty degrees, so the air arrives at your face and not at your hairline. Three speeds, and you will have used all of them before the week is out. Someone will ask to borrow one — you hand it over without a pause, because you have two more and because generosity is effortless when you planned ahead. They charge off anything with a USB port: a laptop, a power bank, the wall. Preparation is not fussiness. On you it looks like foresight.
