KoonieDesk Fan, Ultra Quiet 2.5-11h Battery Operated Small USB Fan with Strong Wind, 180° Tilt Folding and 3 Speeds Adjustable, Battery Powered Mini Personal Fan for Office Bedroom Desktop

This is the perfect fan for my desk. It can really blow and keeps me cool. It has 3 fan speeds and works for several hours on one charge. It folds flat and can be stored away in a drawer easily when not in use

I love this. I work in an office space with 7 other people so naturally we all have different temperature preferences. I like things a little cooler while a couple coworkers prefer the heat. This fan was perfect for me. I can’t speak to the battery life since I have mine close to an outlet so I generally have it plugged in. The low setting is great - quiet but enough power for me to cool down. The medium and high settings are stronger, but a tad louder, so I don’t use those since my working space is small and I don’t want to disturb anyone. I don’t think it would be annoying necessarily, but the low setting is virtually silent so I tend to use that one. I love that it is small and compact. It fits right next to my monitor and doesn’t crowd or clutter my desk. I highly recommend for those who need a small fan to keep them cool is a crowded space!

I love this portable fan! It’s so easy to put in my computer bag, take it to the office & pull it out when needed. It works great & has variable speeds.

These work great. 3 speeds and you can adjust the flow direction up or down using the stand. The battery with last several hours on low speed. I used this to help me sleep during a blackout this summer and I bought 2 more after that. This is too small for sharing. Now my husband and son have their own!

I like how portable it is and the battery lasts. For a small fan it blows fantastic flow of air. Perfect for my bedroom. I'm actually going to buy one for my daughter.

Wanted a small rechargeable and portable fan. This fan meets that and can sit on a surface with it folded out or can hang by the same fold out arm. It had charge on arrival so I was able to immediately try it out. Charging cord includied but not type C plug adapter. Box says LED red while charging and turns green when done, but I haven't tried it yet. At a distance @ 5' I could feel a faint movement of air and barely any sound. Medium setting was a slight increase of both, definitely feeling the air move but wouldn't interfere with a phone call. High was a good breeze and yes more sound but still didn't interfere with TV or phone calls. I wouldn't want it close to the phone as the breeze and the sound might begin to interfere. Would be nice for desk, tent, emergency use or other areas you could hang or provide level stable place to sit. Would keep it dry though.It's surprising how much air it moved yet quite. Box says running at DC 5V. It stands on its own well and feels fairly sturdy. The box has good directions if you have your reading glasses on. (English only) It does state that it has a 1 year warranty with a Yahoo customer support email listed. Yes, it's made in China.Box states the battery should be removed (recycled) before eventual disposal of the fan. Wouldn't it be nice to be able to replace the battery? If it lasts a year plus, I will be pleased.

I have to say this is a nice little fan! It's quiet, it really blows a strong focused wind stream.No, it is not a full sized, or anything like a 6" - 8" or so fan, but it's got the ability to put wind right where you want it, you can just hold it and move it around as well.How long it lasts remains to be seen. It's a sealed unit, no apparent way to open it and change the battery. How long the battery stays viable, and if this will run on USB with a dead / bad battery is unknown.It's minimal design is a plus, I really dislike unnecessary plasticky trim, this folds flat.I'd like to see a larger version of it.Can't beat the price.

The reason I'm giving this fan one star is because:1) The battery life is ridiculous. Even on the low setting, it hardly lasts more than a couple hours. What is the point of a battery life as bad as that? I have it in my office space, and long story short, as long as I have it plugged in, it's fine. But... again, why have a battery for something that basically needs to be plugged in? It's functionally useless as a battery-operated fan if you intend to use it for any length of time.2) It's NOT "ultra quiet." Is it incredibly loud? No. But it's definitely not "ultra quiet." In fact, it's loud enough that people in the next room can hear it, especially when on the "high" setting. That setting is actually quite loud. Again, it's not horrible, but the description is deceptive.3) It supposedly has a "strong wind." Look, this fan is super cheap, so I'm not really complaining about the wind it generates. It works for me. But the idea that it's a "strong wind" is laughable. It's more like "a faint breeze."SUMMARYConsidering how cheap this fan is, it works for me. In fact, I'm not returning it! Yay! I'm going to keep using it. The reason is that I can easily plug it into my computer and not have to worry about the battery life. But if I had been buying it for its intended purpose (having a battery-operated fan that I could use when away from a power source), it completely sucks.

Fan is quiet especially on lowest speed. Lasts a long time on full charge.

Para disipar los humos de la soldadura de estaño al soldar sin tener cables sobre la mesa de trabajo, esto es uso inverso a lo normal. no quiero aire quiero que el ventilador aleje los humos de la soldadura.

Muy potente y práctico,

Super recomendado, no hace ruido para nada en los primeros 2 niveles y es como si tuvieras una mini turbina, esta bien chido.Actualizo, lo compré el 27 de Mayo y hoy 10 de Julio, dejó de funcionar la batería, solo funciona conectado a la corriente

Me encantó, es más pequeño de lo q imagine pero hace muy buena su función, muy práctico
