efluky 3-Speed Mini Desk Fan, Rechargeable Battery Operated with LED Light, Portable USB Fan Quiet for Home, Office, Travel, Camping, Outdoor & Indoor Use, 4.9-Inch, Blue

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! :)

I'm one of those people that cannot sleep without a fan. I need the air circulation and the soft noise. I live in a city that is notorious for the power going out, and I go out of town a few times a year, so I bought this to try out. This fan is small but it packs so much cooling power! I love that it's chargeable. It has 3 settings and a useful flashlight on the side too. It is great to pack for my hotel nights. It helps me sleep.

This is an awesome little fan.I actually own FOUR of these! One for the office, one for home and sleeping, one for travel, and one for lending out. They're quiet, move a LOT of air (on low power, you can feel it from 4 or 5 feet away), and hold a charge like nobody's business. Fully charged, it can run on low for a full night's sleep.Not only have I bought four of these, but others who have seen them in action have ordered them as well. It's a popular item around the office, that's for sure!Perhaps the only downside is the light. It's blue - which looks nice, but red would easier to have on for ambient light and fall asleep to. Other than that, this is a great fan and well worth the money.

This little fan is great. It has multiple speeds and can run on a battery, and charge the battery while plugged in. However, you do not NEED to use a battery. I travel with the fan and I don't bother with the battery since you aren't supposed to keep lithium batteries in your luggage. It even has a built in flashlight! As a fan, it has three speeds starting with the slowest, which is nice. It is reasonably quiet, moreso than most small fans I have tried, and it is very light. That may be the only problem - it is so light that it might walk a bit if the power cord doesn't have enough slack, the surface it is on is slick, or if the fan is on high. I guess it would be nice if you could aim it up or down a bit, but I have never found that to be an insurmountable problem.EDIT: 18 months later, the fan has broken. Actually, the fan is fine and it works with a charged battery, however, it no longer works when plugged into a USB cord. It can neither charge nor run without a battery. The problem is that the female USB socket got bent out of shape and/or pulled away from the circuit board. I might still be able to repair it, but I'll probably just buy another one. It is cheap and quiet and light and I took it on more than a dozen trips, so it was banged around a bit.

This little fan is powerful! It’s light weight and keeps me cool at night on the lowest setting!Highly recommend!

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.
