GEHEN Clip-On Fan with Sturdy Clamp, USB-Powered Fan 3-Speed, Ultra-Quiet Operation Ideal for Bedroom, Office, & Stroller

Bought two. They've been running almost continuously for over a year. At this price, that's more than I expected. Using them in a hot Florida garage where I'm 3d printing, to keep the chemical odors at bay and make the place bearable.

No complaints, it does what I bought it for - to force air across the fins of my apartment's steam radiator. Barely can tell when it's on.

This is okay when a hot flash hits but not to helpful for the summer time.

The fan's attachment clip is pretty versatile being able to hold on to table tops, nightstands, window sills. The clip is larger than I was thinking it'd be and has plenty of grabbing power, without being too cumbersome or too large and clunky.The swivel capability is great allowing you to swivel the fan both up & down, and left & right. And it does this in a way that still makes the power cord of the fan manageable.Having Low, Medium and High settings, you can customize the airflow you want with a button press, with the first press turning it on to Low, another dialing it up a notch to Medium, another button press increasing it to High, and a last button press turning it off again.I've used one of these fans on a solar mppt controller (a device that gets pretty hot and has a built-in heatsink, but didn't have a fan), another in a window for night time fresh air, another on a desk to keep cool while working.It's power draw relative to the air flow is pretty amazing thanks to the brushless motor, which are very efficient motors. I've used one off a USB power bank over night on Low, and the power bank still had more than half its charge the next morning; I feel this lends itself to camping, older tractor equipment that might not have A/C, or any remote task where a bit of cooling powered by a USB power bank is ideal.

Worked ok for about a month then began making rattling noise regardless of fan position. Air flow decent for size and price.

This is a great fan have this as my office at work and noise level is amazing non of other colleagues could hear that it is on. The 3 levels are air flow amazing.

Worked out of the box. There is 3 levels of speed, Low, medium, and fast. Runs pretty quiet on all level with low being the quietest and fast being slightly louder. Air flow is better than expected.Connected it to an old portable power bank that I’m no longer using and now I have my very own portable personal fan.Great for desk and table with the clip clapped to the edge or resting on top. Also have a spot to hang it on wall. Also have a small hook built in at the bottom if you want to hang it.Used it to cool my bowl of noodles so I don’t have to blow to cool it down before eating.Fan rotation is exceptional, almost 360 coverage.Great value for the money

Really like the overall quality of the fan. Made of durable material and easy to clip on the dorm room bed. The only think I disliked was that it didn't come with a USB charging block only the cord.
