#2 Efluky Three-Speed Mini Desk Fan with Rechargeable Battery – Honorable MentionWHY WE LIKE IT: The 4.9-inch Efluky mini desk fan might be small and portable, but it offers great value for its price with its 3-speed settings, LED lights, and built-in rechargeable batteries. It’s ideal for employees and students who have to endure a grueling commute to get to their destinations.
The Efluky USB fan comes with two rubber strips at the base that reduce noise and vibration. Given that it has three speed settings, the anti-slip pads will come in handy when you switch to the highest speed.
Its rechargeable batteries can last up to 9 hours on the lowest setting and at least 3 hours on its highest setting. Thanks to its fast-charging capabilities, it takes at least 2.5 hours to recharge. The fan also has internal and side emergency lights, which you can easily activate by tapping on the power button for a certain number of times.

Its advanced features are encased in a small, sleek matte black casing, making it an inconspicuous addition to an employee’s desk.
Aside from having touch-sensitive controls, its aluminum alloy stand features an anti-shake design. It has two anti-slip rubber strips that reduce vibrations. Even at its highest setting, the fan will stay securely on top of your desk.
#5 Opolar Mini USB-Powered Desk Fan – Best BudgetWHY WE LIKE IT: The Opolar USB-powered desk fan features a stable, space-saving, 40-degree articulating head and whisper-silent design. You can take it with you by your bedside and still sleep comfortably.

#6 Holmes Heritage Mini USB Desk Fan – Best for Home DecorWHY WE LIKE IT: The Holmes Heritage USB fan is the most aesthetically pleasing fan we’ve ever laid eyes on, with its 4” blades, retro design, and brushed copper finish. Anyone who wants to stay cool and in style will love this desk fan.

#7 Keynice USB Desk Fan – Best ValueWHY WE LIKE IT: The Keynice USB fan is a highly versatile option that you can clip onto or place on top of a steady base and rotate 360 degrees. Thanks to its clip, you can keep your child happy in their stroller on a sweltering summer day.
Measuring 8.1 x 7.8 x 4.2 inches, the Keynice USB fan is the largest on our list, with a cable that reaches 4.9 feet long. It might not be as small as other fans on this list, but it’s just as convenient and useful. 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 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:
- 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
- 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.
- 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.
- Are USB Fans Worth It?
These small, ultra-portable cooling devices can produce a soft, refreshing breeze, enough to lift your mood on a hot summer day. Most USB fans have excellent compatibility with electronic devices, allowing you to use multiple power sources. If you’ve followed our guide and considered our selection, you will surely find a USB fan that’s worth the purchase.
