Where has this been all my life? I never write amazon reviews, but I was so impressed with this product that I just had to make an exception...I am a chef/manager so half of my time is spent in a hot kitchen, and the other is spent in an almost equally hot office. I was looking for a USB fan that could give a little respite and I absolutely hit the jackpot with this one!Where do I begin? On its lowest setting, this fan provides a gentle breeze from almost 2 feet away. It is quieter than most computer fans. Second setting is something similar to the highest cool setting on the most powerful hairdryer you've ever owned. A shade louder but completely unobtrusive and still easily felt from 2-2 1/2 feet away. The third setting is more powerful than some regular fans that I have owned, and still pretty quiet at that.It is charged via USB and it uses the same lithium ion battery that is found is most e-cigarette vape mods. In a pinch, you could take the battery out of your vape and use it to power this fan. Plugged into a USB charger/port it charges whatever battery is inside it. So if for whatever reason... if you wanted, you could conceivably stealth charge your vape battery. Plugged into a USB port the fan also works without any battery installed at all. You can also take this battery and put it in your vape battery charger if you have one and charge it that way.A fourth click on the "on" button turns off the fan and activates an LED light on the side. It isn't as bright as the one on most smart phones these days, but I could see it being useful in certain situations.At any power setting, if you hold down the "on" button for 4 seconds, an LED illuminates the blades in the center of the fan. It is a cool looking effect, though I wouldn't personally use it unless it was plugged in as it would just put additional drain on the battery.Finally, it is a nice compact size. That is perhaps is the most impressive part, especially considering how much power it has! I have included a picture of it in my hand. Admittedly, my hands are a little on the large side, but it would still slip easily into a laptop case or perhaps a purse. It is only about an inch and a half thick.If you're looking for a small USB/battery powered fan you should get one! It's FANtastic! :)

When my wife and I go, cruising, there is always a problem with the room, being cool enough and the thermostat in the room not being very responsive. We read reviews of this on Amazon and we’re very skeptical. Lo and behold we got this in our hand and plugged it into a USB charger, it worked perfectly! We used it on the last cruise that we took, and it was actually the first time that we were comfortable in the room with the fan producing an incredible amount of circulating air for the little product that it was. We had to keep it plugged in to have it working all night and the battery power Seem to run out after an hour and a half but being able to have this little fan point at the bed was a blessing. We will never go on a cruise without this fan or one similar to it. The price was very good and it is small enough to put into a backpack.

I bought this fan to put in a hotel room or cruise cabin while on vacation. It fits nicely in a suitcase and sits on a bedside table. It also has a USB charger and actually holds a charge for a long period of time. I like the fact that it has different speeds and has a light in case you get up a night, you can see in a dark room. I recommend this fan. It has really been a great purchase.

The first unit I purchased was not rechargeable and only worked while pulled in, I returned it, and the replacement was able to hold a charge. I love it! It is perfect for travel and when I go places I know will be hot.I ordered a third for my desk at work, it is not rechargeable but I kept it b/c it is still a powerful little fan.

Not only is it super cute but the fan is very powerful for being as small as it is, I also love the blue light it comes with, and the air flow is amazing.

I sleep with a fan on every night when I am at home but, I travel often and its not easy to bring my fan with me. I wasn't sleeping well with the awful noise from the fan app on my phone that I had been using. So, I tried 5+ small fans and this was the one I ended up keeping. I absolutely love this fan. It keeps me cool at night if I have it facing me and the white noise helps me sleep. There are 3 settings - high, medium, and low. I have used both medium and high and love them both. Its very small and compact so, its easy to transport compared to some of the others I tried. I'm not sure how the battery life is as I've kept it plugged in every time I used it. I highly recommend!

Stopped charging and the charger port broke. It was low noise. Had great airflow. Not a bad fan just can tell it’s cheep.

Going on holiday it’s great for that sort of thing , can be charged , like your mobile. Perfect.

Its good though I did expect a bit more air flow but still good
