4 Inch Fans

"Battery life milage may vary for you, but I got a good 6 hours cordless on speed 4 with no mist. The manual says 4 hours on speed 3, which I easily exceeded. ...There are 5 different settings for air flow. 1-3 are quiet yet soothing. 4-5 get the job done but it’s not an obnoxious sound- I could for sure fall asleep to the hum of it. "

"It was a life save for me while traveling through Europe under heat dome, it is actually reducing the temperature around your head and neck around 3-4 degrees, which makes a lot of difference. Battery is good for 2-3 hours constant use, and you can control the device from your phone if needed....Also i work 12 hour shifts and i get around 4 hours of battery life. But thankfully they will run off a battery pack in my pocket so the mild inconvenience of being teathered beats nothing at all. "

"It is very quiet on low, but I can barely feel any air movement from 12 inches away. It makes some noise on medium, but it isn't bad, and you get minimal airflow. ...I do wish it was maybe 2 inch taller as well as it is on my desk and blows on my chest and would be nice it it got some of my face."

"This is a great little fan. I bought 4 and they are really powerful for being so small. ...It has a timer which can be set from 1-4 hours and oscillates vertical or horizontal. "

"good remote options and the 4 hr timer is great.quiet too with lower settings!...Great presentation works well for our upstairs where it is generally 4-5 degrees warmer."

"Make sure this cooler is not higher than your case. 1/8th of an inch clearance for me. Cooling performance for the price is at the top....Make sure your case base at least 6.5 inches on clearance for this beast."

"I use it in my jeep camping and 4 wheeling....This multi-volt brushless 4 inches clamp SKIL fan is amazing!!!! The fan is very easy to attach to any surface, and it works wonderfully. "

"Despite its compact size at just 7 inches, this little fan packs a serious punch in terms of power. "

"The Vornado Portal Window Fan is a game-changer for anyone looking to improve airflow in their space without sacrificing style or functionality. Standing at just 6 inches tall, it’s sleek and unobtrusive, blending seamlessly into any room’s aesthetic. "

"Powerful, doesn't take up a lot of room and keeps thing cool. Reason it got 4 stars and not 5, is that on the highest setting, its a bit loud....I've owned this fan for 4+ years. It's not known for being quiet, perfect white noise for sleep. "

"There are several different settings- you can pull air out of the room to outside, push fresh air inside and 4 speed settings. The auto temperature controls work to maintain a set temperature and a display to show room temp. ...Not only is is very quiet and has 4 settings, the low profile of it is very aesthetically pleasing. "

"Nearly silent operation at all 4 speeds. Alexa functionality is an added bonus....Just a simple push of a button. It has 4 speed settings. It has a good bit of power for such a small fan and it's quite. "

"Awesome fans with some good power! I have 4 of them in my tower....Very quiet. Comes with 4 pin to molex adapter."

"[This review was collected as part of a promotion.] I bought this 7 inch multi volt brushless fan a month ago and I’m so happy that I did! ...So far, I own two of them, and I love them. My latest 7-inch Brushless fan is perfect for small spaces or an office. "

"There are 5 levels. Only levels 4 and 5 make a whirling sound."
