AceMining Desk Fan, Quiet Small Fan, USB Fan for Rooms, Rechargeable Table Fan Battery Operated Desktop Fan, Portable Office Fan with 3 speeds, Bedside Fan Electric Plug in

At the affordable price, I initially doubted the quality of this fan. I was afraid they would have had to take a shortcut somewhere, that would degrade the long-term usability of it. I've used it for several weeks now and I am pleased to say that my doubts have Gone Up In Smoke!As long as I keep it charged, I've not had a SINGLE problem. The low speed is perfect for night noise/air, and general heat-discomfort. I work in a WIDE variety of spaces doing remote tech repair. It might be a manufacturing plant kept at a solid 60 degrees F in the winter, or a elderly couples home where it's always 90 degrees F. When you're working in a tight space and in high temperatures - a strong fan quickly becomes a necessity. Especially since technology is so sensitive to water intrusion. One drop of sweat could fry thousands of dollars of equipment. This ingenious portable fan is priced just right, but (in my experience with it) worth Thrice the price. I cannot really give a rating of the time to failure ratio of the battery, but the run-time is excellent. More than enough hours on the battery to last a typical shift of on-site tech repair.At low speed the noise is noticeable, but not obnoxious. More than 10 feet away and ambiance overcomes the sound.At medium speed the noise is more noticeable, but won't drown out anything important to hear. This is about the highest setting I use on a normal basis.At high speed the noise is still not obnoxious. The force of the wind is excellent compared to the noise level.The only problem I have experienced: Using the product while Also charging it. After about 10-15 minutes of a difficult printer repair the fan stopped working. After I unplugged it, it started working again, but only a short time because it was only charging for a short amount of time. My guess is that the charging circuitry is not heat-synced. It could have been a failure of the (borrowed) device I used to charge it, but without a reliable means of troubleshooting and the job I was on, I couldn't fully diagnose the issue. Bottom line: keep it charged when you know you're going to need it. Use a personal, reliable charging device, and you too will be glad you spent the money for such an effective and ingenious device.

I Love this AceMining Fan! Like another reviewer, I have a medical condition that causes me to get overheated and feel like I am burning up. It occurs all throughout the day and night. I have bought many fans, and this one is, by FAR, the BEST one I have found. I bought a second one, because I would be lost if anything happens to the first one. The fan is not too large, and I travel with it everywhere I go. I use it in every room in my home, in the car, at work, in the Dr.'s office, and even outside. It is powerful enough to create a cooling breeze, even on the lower settings, yet quiet enough that I can use it in public without drawing a lot of attention. It charges quickly, and the battery lasts much longer than others I have tried. The battery is totally adequate. The fan part itself swivels in the base, so I can easily direct the breeze where I need it. (I can stand it on the counter, and have a cooling breeze at my face when working in the kitchen.) The only small improvement I think it could use is to add a bit more weight to the base, because I find I knock it over easily. But it is well made, and has stood up to hard and frequent use...All throughout the day. Every. Day. I love it.

I just received this fan today, so obviously I haven't been able to give it a huge testing period, but wanted to leave a review of my first impressions. (If needed, I will come back and update.) I bought this fan to use in case of a power outage. We had one the other week and I did not like not having the option to put a fan on in case I needed it (it's winter and I still use a fan at night, don't judge me. lol But I also sometimes need a fan on me if certain health issues are happening). I picked this fan because the battery amount was more (3600mAh for this one vs 2200mAh for another I had considered), the price was good, and it doesn't take up a lot of room. I was worried that the lowest speed wouldn't be good enough (meaning I would have to use more battery), but the lowest is a good speed and I think it will do great for what I need it for. Then again, I am writing this in the middle of January. I may change my mind in July when it's over 100° here in California, but let's hope it still does a good job and/or there are no power outages. I also like how well the fan works even though it is just centimeters wider and longer than my cell phone (Galaxy S7).

This thing is very quiet, even on the highest setting, and it puts out surprisingly good airflow. You should note that it's very small, so the breeze it puts out is in a fairly narrow cone. It works great as a desktop fan which is what I bought it for, but if you're planning to be some distance from it, you should probably go for something bigger.

Suffering from the heat of our undercooled home, this is my go-to fan for when i'm at the table eating, or sitting watching TV. It is so quiet and yet efficient, that I bought a second one for my workouts on the treadmill. The fan can be tilted in many different ways, and so I prop it up on the front of the treadmill, set it on the highest speed (it has three speeds) and it helps me enormously as I walk at speed on the treadmill. Recommend this highly!

I bought this for my desk at work. I read reviews on a lot of products before giving this one a try and I am SO glad I did. It is small but packs a well needed punch in my, often times stuffy, cubicle. I love that it doesn't require a plug in since those are located way under my desk. I will admit, I thought mine was broken at first. I plugged it into the USB port and tested the buttons. The low setting was great and SO quiet. Then I changed it to medium and then to high and the speed of air flow did not change. Then I came back to the product info and read that is supposed to happen, while charging. After a full charge I unplugged it and the speeds did change just fine. Coworkers are also impressed and I love how light, but sturdy it is and that I can change the direction without having to move it much. LOVE this little fan!

Muy cómodo... Fácil de cargar y de llevar..super recomendable ... Chiquito pero bastante bueno

Con una carga completa, obtuve 10 horas en el nivel 3 como máximo. Es bastante pequeño y no muy sólido, pero por el precio, lo recomendaría ya que tiene una potencia razonable y dura todo el día.
