Best USB Fan

Even in air-conditioned rooms, small, portable fans are ubiquitous. So you can stay cool on warm days, we spent last summer testing out 25 USB fans to find seven of the best.

Out of all the fans we tested, Arctic’s Breeze Mobile was the most convenient, quiet, and refreshing USB fan. It might be small and lightweight, but it’s still powerful enough to deliver high air flow. Compared to our second pick, Efluky’s Rechargeable Mini Desk Fan, the Breeze Mobile is more a portable fan. You can take it everywhere you go—even on your daily commute—without attracting too much attention. Read on to find out more about it and the other six USB fans we tested.

Top 7 USB Fans Compared

If you have a child, you can simply clip it onto the stroller to keep the little one happy and less fussy on a hot day.

This fan, unlike a few of the options on our list, can rotate 360 degrees, so you can direct the airflow in the ideal direction. Given its design, you’ll likely want to use it with a power bank as there is no built-in battery, though if used at home or the office that will be a non-issue.

How We Decided

USB fans come in all shapes and sizes. For our list, we focused on compact and portable USB fans that you could easily place on top of a desk or inside a backpack. That’s why we chose personal fans that were less than 10 inches small, but we also made sure they were powerful enough to provide extra cooling. Since USB fans are often used in the office or in the bedroom, we eliminated ones that would affect the quality of your sleep or work. Stability was also an important factor in our decision-making process. We selected sturdy fans that wouldn’t easily get knocked over.

USB Fans Buyer Guide

The Most Important Features to Consider

Given the wealth of options on the market, choosing a USB fan is a lot more challenging than you might think. In your search, you might want to consider the following features:

  1. Oscillation – An oscillating fan has the ability to swing from side to side, promoting better air flow. That means a fan with such a feature can cool a room faster without having to increase the speed of the blades’ rotation
  2. Speed settings – Since USB fans are often compact and portable, they usually come with a single speed option, which is measured in revolutions per minute (RPM). However, you can also find fans with two to three speed options, ranging from 500 to 1,800 RPM, despite their small sizes.
  3. Power options – Some USB fans are battery-powered. You can use rechargeable or disposable batteries to keep them running, which is very convenient especially when you’re nowhere near an outlet. This additional feature is useful if you enjoy camping and other outdoor activities.
