The Best Mini Fans to Keep You Cool on the Go
As their moniker suggests, these portable pint-sized companions are designed to keep you feeling cool and comfortable by proving a nice, gentle breeze. They come in a spate of different styles but are typically fitted with batteries so they can be moved to different locations if need be.
Compared to air conditioners, mini fans are quieter and less expensive to run. They’re also much easier to set up and offer more flexibility in terms of positioning. There’s no way you could strap a window AC unit to your treadmill or baby’s stroller, whereas you can a mini fan.
