This fan is a great size for taking along when you need a portable fan, and also works well for a breeze at my desk. It comes with a USB-C charging cord. It takes about 6 hours to fully charge, but you can use the fan while it is charging. It is very lightweight, only weighing 14.5 ounces. The clamp has a strong spring and is lined with foam to protect your surfaces to which it is clipped. It also sits securely upright on the clip base. The clip/base is 2” wide x 5” long x 1 3/8” thick. The jaws will open out as much as 2”. It holds securely to whatever you clip it and does not shake free even at the highest fan setting. The power button, charging port, and USB port are on the back. The battery is 10000 mAh and you can charge a phone or other USB device. The fan has 3 speeds. At the lowest speed it gives a nice breeze and is very quiet. At medium, the noise is noticeable but not intrusive. At highest speed, the breeze is very cooling, but it is also very loud, but no more so than any other fan blowing at that speed. The fan opening is about 5 1/4” diameter. The plastic blades are 4” diameter. The housing cage is 2 1/2” deep. The openings are small and closely spaced and the blades are set back 1” from the front so it is quite safe to protect little fingers from reaching the blade. My only minor complaint about this fan is that you have to cycle through the settings to turn it off, but it is a small inconvenience for such a useful and powerful fan.

The cord is so short. I tried to plug it into the outlet under the window I intended to clip it on, and it wouldnt reach.

The most important part of any fan is that it can blow adequate air volume. This unit meets that requirement. Its quiet enough and the quality is on par with most other fans in its class. The clip is very convenient as I clip it to the steering wheel of my car when Im on the ferry in the hot weather when they dont let us run our engines. It serves its purpose well.

Air-conditioned offices can get very stuffy unless you are fortunate enough to have a desk underneath a blower. Not having been so lucky, I obtained several small portable fans over the years to put on or around my desk to keep me cool. Now that I’m home, I still spend several hours a day near my computer in an equally poor-circulation room. I was down to my last personal fan when I saw the Gehen clip-on fan on Amazon and ordered it. This fan turned out to be more than I expected. It’s the best small portable fan I’ve ever used. The Gehen fan is black plastic, with three translucent circular blades. It sits on a plastic clip-on base with four tiny circular rubber feet for traction. The fan assembly is circular, measuring 5 ½ inches in diameter. The fan and base are eight inches tall when sitting on a flat surface. There is only a 3/8 inch gap between the individual braces on the front and back of the Gehen fan. Therefore, children or careless adults can’t stick a finger or pencil inside and cause damage or injury. However, the front of the fan is easily removable, allowing you to clean any accumulation of dust inside. The fan rotates 360 degrees horizontally and vertically, allowing you to point it in any direction, no matter how it is mounted. This fan operates on a hard-wired USB power cord with no battery backup. The cable is about 45 inches long. You shouldn’t have a problem attaching the cord to a spare USB port in most office settings. But it may limit the fan’s use in places like bathrooms or bedrooms unless you have a converter or USB plug-in. The fan has three speeds and rotates through those speeds from slow to fast by pushing an easy-to-locate 3/8 inch diameter button on the back center of the fan. The fan’s base is a giant clip that measures 2 ¼ inches wide by 5 ¼ inches long. Even at high speed, the fan rests securely on its base when placed on a flat surface. There is no movement, shaking, or rattling. The clip has a powerful spring that requires considerable pressure to open. Children or adults with weaker grips may be unable to open the clip. This clasp can fasten securely, either vertical or horizontal, on any table, desk edge, or similar object up to about 1 ¼ inches thick. The inside of the clip is padded so it won’t damage any surface to which it is attached. When the clip is attached, the fan doesn’t vibrate, rattle, or shake. A fan’s primary function is providing good circulation; the Gehen fan does an excellent job. Keep in mind this is a personal fan, not a room fan. It won’t supply circulation to an entire room. However, I can still feel a noticeable breeze up to about six feet from the fan at high speed. At the two lower speeds, the fan makes almost no noise when I sit two or three feet away from it. (When you place the fan in a new configuration, settling down can take a few seconds.) At high speed, there is a slight, non-distracting noise. Either I’ve grown used to it, or the noise has decreased since I installed the fan. I’ve had considerable experience with personal fans over the last decade, and the Gehen is the best I’ve ever used. It’s almost silent, powerful, and highly versatile. You should be able to set it up in almost any office or computer desk environment. The only drawback is the limitation imposed by the power supply. If you have a power source available, this fan will work well on a nightstand, bathroom counter, or similar location. I would rate this fan 4.5 stars if I could, but I’m rounding it up to five stars based on the overall quality. The Gehen fan is a great way to keep your cool.

Its my third days using it. Money wasted! I bought a Reeno 5000 and was amazing, only didnt has long batterie live. But this, a snore has more power!!!

I couldnt be happier with this 3 Speeds Clip on Fan. Easy to use: The fan is incredibly easy to set up and use. All you have to do is clip it onto a surface and plug it in. There are three different speed settings that you can easily adjust using the buttons on the fan. Compact and portable: This fan is small enough to fit on a desk or table, and its also lightweight, so its easy to move around. The clip-on feature is very convenient and allows you to attach the fan to a variety of surfaces, including desks, shelves, and even bed frames. Ultra-quiet: I was impressed with how quiet this fan is. Even on the highest setting, it doesnt make any distracting noise. This makes it perfect for use in an office or bedroom. Powerful airflow: Despite its small size, this fan is powerful and provides a great amount of airflow. I was pleasantly surprised by how well it kept me cool during a hot summer day. Affordable: This fan is very reasonably priced and offers great value for money. I was impressed with the quality of the fan, especially considering its low price point.

Great little fan for personal use. It Uses a USB plug to operate. Got it for traveling internationally as the USB is easy to find/bring. 5 volt power.

This is a small, desktop rechargeable lithium ion battery powered fan that moves a remarkable amount of air. It comes with a cable to connect to a charging source. It is unusually quiet and has a good solid clamp on the bottom for affixing to a table or desk top. The fan has 3 speeds and it rotates. It also has indicator lights that show the level of charging.

It seems cheap and junky and apt to break easily.
