USB Desk Fan Portable Mini Fan Powerful 3 Speeds Wind Personal Desktop Fan with 360° Head Rotation for Home Office Car Indoor Outdoor Black, No Battery, 4.5 Inches

These little fans are surprisingly powerful and seem to be very dependable after a few months of heavy use. They are excellent fans for the price. I bought 4 of these in the spring to put in my seedling starting cabinet to promote airflow and mimic wind to help the plants grow strong stems. I left them running for 24 hrs/day and they never quit. Now I am using one at my desk to keep me cool, and even the lowest speed is usually enough for that. The air flow is very good. The first (lowest) speed is pretty quiet. It is mostly a nice white noise. The higher speeds are a bit noisy but nothing bothersome, and I think it's reasonable for the price and power. The fan also sits stable on my desk. I like the easy on/off button on the back, and the fact that I can plug it straight into my laptop with the USB plug.

PAID $7.29 on 11/02/2025 for the 4.5" TRIPOLE KW36. 5 STARS for the petite handsome simple form and notable performance of the KW36. There are endless 5" USB desk fans under $10, but this little 4.5" gem rises to the top of it's class, IMHO. I run my USB fans on LOW, practically around the clock, for personal cooling ... as an AC assist in my SW Florida home. The KW36 is at least as strong on LOW (maybe even stronger, but with a somewhat narrower path of wind) as the bigger uglier 5.5" LIANGJJ fan that I'm replacing - see photo. (After years of use, the LIANGJJ started making a plastic-y rattle that I couldn't fix). It's QUIET enough on LOW, with a pleasant white noise in a quiet night environment. The two higher settings are noisier than I want in a quiet environment, or for making a phone call in very close proximity, but at least it's a white noise, albeit higher pitched than LOW, that isn't terribly annoying beyond the unwanted decibles. I love the SLENDER form of the KW36, its fan head barely wider than the 1.5" wide base. I'm tempted to get more as gifts and concoct a reason to get myself another in a pretty color.

Good fan no complaints from myself for this product, very powerful three speeds you will be surprised by how small this fan is but yet the wind it can produce, portable for carry on for a vacation, bedside or office space, I purchased these fan approximately six months ago seems to be durable no lost in power, performance does include a approximately 6 inches long usb cord, now battery life can’t account for due to I just leave it plugged into a usb receptacle continuously never used the battery operated option yet but yes would recommend to anyone looking to purchase a new small fan

I have this plugged in all the time. I like the black color; it blends in with my set up. It's a well-made little fan with three speeds. Pretty light. The hinges let you move it up or down. It's decently quiet. It's not really noticeable until you crank it up to the third setting, which is its fastest setting. It does its job keeping my mini pc cool when I over work it.

Love this little fan! It puts out a good amount of air for as small as it is. It is also quite, hardly any noise so it is perfect for my desk at work. I also got one for my vanity. The price was unbeatable. I have been using the fans daily for almost a year. I use the one at work about 6 hours a day 5 days a week, no problems with it so it is a great quality item. I would definitely recommend it.

Addicted to fan action :) Liked these first one so much, I bought 5 more for all around the house. They look nice, are lightweight and have a tiny footprint. Plugs into any standard usb but doesn't include a block. I also tested it works plugged into the usb outlet on a lamp and even a battery bank. Whisper quiet on 2 lower modes, 3 speeds, strong breeze.

I purchased one based on the reviews here and I'm now buying two more. These fans run on almost no power, will run all day on a small pocket size battery bank. The perfect thing to have on a hot night when the power goes out! Also a small breeze is all you need to keep the mosquitoes off of you when you are working outside. They are small enough and cheap enough to stash them around so you have one when you need it. I measured the power usage: Low pulls 1 watt Med pulls 2 watts High pulls 4 watts

I recently travelled overseas and had several hotel rooms with no ventilation. For two of them I was able to get a fan from the front desk. For the others sleeping was not pleasant. I knew I needed a small fan to take on travel. This model is compact, has three speeds and should be great. I kept the original box so I can safely pack it in my suitcase. For now I have it on the kitchen table to cool me off on breaks from working in the yard. So far so good! Recommend.
