OPOLAR Mini USB Powered Desk Fan, Small Buy Mighty, 2019 New Quiet Portable Fan for Desktop Office Table, 40° Adjustment for Better Cooling, 3 Speeds, 4.9 ft Cord Review:

The portable personal fan for desktop office table that I am currently using on my computer desk is the Black and Blue OPOLAR 2019 New Mini USB Desk Fan with Updated Strong Airflow, 3 Speeds, Whisper Quiet, 40° Adjustable Tilt Angle for Better Cooling, and Perfect Portable Personal Fan for Desktop Office Table. The height of this fan is six and a half inches, and its width is five inches. For such a small fan, this one is really quiet and produces enough of air at all three settings. This USB fan is brand-new to me, and so far it's been functioning perfectly. My previous USB fans weren't quiet enough and ceased functioning after two months. It should last a full year, please. If this fan quits working within a few months, I will update my review. I adore it so far.

SmartDevil Small Personal USB Desk Fan,3 Speeds Portable Desktop Table Cooling Fan Powered by USB,Strong Wind,Quiet Operation,for Home Office Car Outdoor Travel (Navy Blue) Review:

I LOVE this SmartDevil Personal Fan! I didn't realize what it would and could do when I got it to replace my desk fan.This fan has above my expectations because it is lightweight, powerful, and cools like my own air conditioner. I purchased the blue model, which is more of a blue/gray and has three speeds, only two of which I have yet to utilize. Incredible cool at first speed. It is extremely silent and spins 360 degrees. My coworkers frequently make comments about it.Although I've only had it for a short while, this has been one of my best yet most unexpected purchases to date. If it keeps performing as well as it has over the past month, it will have more than paid for itself multiple times over. Do not think twice about buying this tiny fan. You won't be dissatisfied.

Small Desktop Fan Quiet USB Air Circulator Fan with Anti-Slip Pad, Perfect Cooling for Office, Dorm,Camp,Laptop,Library Review:

A nice tiny desktop fan with a 3-speed motor that runs on USB moves a respectable quantity of air. Even on my stand-up desk, which is lifted and lowered repeatedly during the day, the rubber pads keep it stable enough. There is a small bit of noise, but it is to be expected given the volume of air moving at the higher settings. Although it lacks a built-in rechargeable battery, I have several USB gadgets charged by a 6-port smart USB charger at work and only use one of those ports. I initially purchased two of these fans, gave the second one to a coworker, and then went ahead and purchased two more, keeping one with my travel accessories and keeping the other as a backup.

OPOLAR 4 Inch Mini USB Desk Fan, 2 Speeds, Lower Noise, USB Powered, 360° Up and Down, 3.8 ft Cable, Powerful Black Fan for Home and Office Review:

UPDATE: After over six months of ownership, I've raised my rating to five stars. This works REALLY GREAT when connected to a reliable power source*.To use by my bed, I recently ordered a second one.In relation to power... During a full-day meeting, I hooked this into a RavPower dual-USB power supply, and it worked perfectly! The fan operated normally and even ran all day using only around 10% of the power from the power pack. In any case, this is a keeper!My only issue is that it can vibrate away from you on high, but it is a very simple remedy.Original assessment:This works fantastically when connected to an old Apple iPhone USB wall charger! In fact, since it's so lightweight, on high it works so well that the vibrations cause it to shake its way across my desk. Those are really the only two things I have to complain about.I tried to plug this into the USB port on my monitor, but even though it has power, there isn't enough power to power this device at the same time.I could easily plug right into my computer if the cord was a little bit longer.I rounded up to 5 stars since I still think that, given my two objections, the rating should be closer to 4.75 than 4.25.

VersionTECH. Mini Handheld Fan, USB Desk Fan, Small Personal Portable Table Fan with USB Rechargeable Battery Operated Cooling Folding Electric Fan for Travel Office Room Household Black Review:

What a beautiful tiny fan! This fan is a lifeline for me because I reside in Florida, where it is hot and muggy virtually all year. The first time I tried it, I was astounded by how well this gadget produces chilly air. There are three huge and three little blades, all of which have a sort of curve to them and are angled just perfectly to produce a lovely cooling blast of air, so I suppose that might be the cause.I liked it so much after purchasing one that I later bought two more. I usually have one on hand since I keep one in my handbag, one at the office, and one on my nightstand. The fan charges easily and retains its charge for a long time. They are used frequently throughout the day, and I don't know what I would do without them.One little flaw that I did find with the fan was that if it was folded or unfolded while it was running, the fan would shut off and stop functioning. Despite this, I still give VersionTech five stars for their fantastic customer service! They shipped a new fan really away when I contacted them because it was covered by their guarantee. I was overjoyed to get the replacement one and used it with pleasure until the same minor issue reappeared. I was hesitant to get in touch with customer care again because I didn't want to bother them, but I did and they once more sent me a new fan. I make careful to never fold or unfold the unit while it is in use now that I am aware of the bug, and I have never experienced a problem since.I urge you to get this fan. Once you have one, you won't want to live without it because it's so fantastic. I've been an Amazon shopper for nearly ten years, and I can honestly say that this is the nicest thing I've ever bought there. A happy consumer is the result of a great product and excellent customer service.

Aluan Desk Fan Small Table Fan with Strong Airflow Quiet Operation Portable Fan Speed Adjustable Head 360°Rotatable Mini Personal Fan for Home Office Bedroom Table and Desktop 5.1 Inch Review:

This tiny fan is so adorable! Here, the climate is hot and humid. The gloomy summer weather has me quite upset. For me, the fan is a lifesaver. It has incredible power and generates a forceful wind. It simply occupies a minimal amount of space on my work table due to its compact size. I sit so far away from the air conditioner that it is almost worthless to me. I constantly perspire after walking from the metro to my office. At high speed, this little fan helps me cool off immediately, and at low speed, it keeps me cool while I work. I'll get a second one for my bedroom. I would definitely suggest this fan because it is incredibly quiet.

iKross USB Fan USB Mini Desktop Office Fan with 360 Rotation - Black for PC Computer Laptop Chromebook Ultrabook Review:

I examined three fans.Ikross (this one): excellent Power switch on the back, stable base, vertical adjustability 100%, sound audible in office environment to 9 ft, breeze to 2.5 ft, detectable on back of hand to 4 ft, moving open napkin to 9 ft, power usage 2.5 watts.This Smart Frog by Huluwa version has an incredibly focused breeze that is good to 4 feet away and perceptible on the back of the hand from 6 feet away. Moving an open napkin to a distance of 12 feet, a two-speed touch switch, a semi-stable yet versatile base, vertical adjustability of 75%, and sound audible in an office setting at a height of 14 feet and a depth of 7 feet. power use of 1 watt!Good Colmx Breeze reaches 3 feet, is felt on the back of the hand at 5 feet, and moves an open napkin at 11 feet. Without a switch, without a wall mount, with zero vertical adjustability, a firm base, and using 3.25 Watts of power, the sound is audible in an office environment beyond 20 feet.

Treva 10-Inch Portable Desktop Air Circulation Battery Fan - 2 Cooling Speeds - With AC Adapter Review:

ran on batteries for NINE HOURS!!! For a gathering outside, I purchased two of these units. I brought a lot of D batteries because I figured the fan would exhaust them quickly (no fan could run for 8 hours, right?!). Although I first followed the instructions and set both fans to low, my wife quickly changed them to high. In the sweltering 95 degree heat of Florida, we were inside a pop-up tent for an event on a concrete street. We just forgot they were powered by batteries after a few hours, and strangers began to enter our tent and use our fan to take air ( ha ha ). We never switched the batteries, and by the time the event was over, I discovered that the crazy fans had been running nonstop for NINE HOURS. They are both faultless.These are obviously coming along with us from now on. I am incredibly impressed, made even more so by what occurred the next day. So when we got these units home, I removed the batteries and decided to place one next to my bed so that I could use it at night because it provided a pleasant wind. This fan was connected in.The storm that knocked out the electricity at 10 AM didn't stop this fan from running for five minutes. The fact that the batteries were dead yet the fan was still running perplexed me. It turned out that the fan is so effective that it was practically drawing power from the capacitor's stored charge in the power brick the unit is powered by.I'm genuinely speechless at how amazing that is. NOT A BATTERY. ZERO POWER Even though everything else in my house was dead, the device continued to run for 5 minutes only on the stored energy in the power brick that was plugged into the socket.

D-FantiX Small Desk Fan USB, 4 Inch Metal Antique Desktop Fan USB Powered Mini Personal Fan for Home, Office, Bedroom (Black) Review:

I adore this item! I got it for my workers who are always lowering the air conditioning down. Now that I'm saving money on electricity, everyone is more at ease. It is very compact and easily fits on the desktops. We plug it right into our monitors, which have ports, because it is USB. So there is no need to find an additional outlet or a long cord. Surprisingly, there is wind. That's why I normally steer it away from my face. But they are so quiet that I don't hear them whether I'm working, talking to a client, or on the phone. The main drawback is that there is just one speed. But it never becomes a problem. In the rear office, I have a conventional table fan, but it is excessively powerful, loud, and heavy. These tiny fans are the perfect size for my desks at work. They also appear to be well manufactured. They should continue for a while.

Fancii Small Personal Desk USB Fan, Portable Mini Table Fan with Twin Turbo Blades, Whisper Quiet Cyclone Air Technology - for Home, Office, Outdoor Travel Review:

As of now, so nice! In the summers in NorCal, I use this as the van fan when I go camping or sleep in a VW Weekender. Test runs in Yosemite and Sac were successful.Pros:whisper only! The background noise from outside is still audible (read: bears, critters, vermin, etc.)really thin and small design!wonderful for open office spacesA broad variety of solutions are available for USB power: laptop, auto adaptor, phone brick, portable USB station, and almost anything these days.Outdoors, solid up to 3 feet distant, and no cross breeze.Cons: The extremely sensitive power button may drive some OCD people crazy if they move it. You won't hear yourself switch off because of how silent it is.Even with a little more noise, one more gear up would be ideal.Don't tug on the power cable too hard because it is fastened to the appliance. It's not a deal breaker by any means, but I'd prefer it to be micro USB for additional setup and storage options. In reality, none of these are.Reality: You can feel the jet from up to 5 feet away when contained, but it needs to be pointed directly at you to be useful. I believe you should give this a try as long as you are not anticipating the love child of a tornado and an air conditioner.
