I was looking for a quiet, small, & discrete desk fan for work. They added more printers into our small office and its increased the heat quite a bit. I purchased this fan and I am seriously impressed with its power! I have it plugged into my laptop without the battery in it and it worked excellent immediately. I actually had to turn it down to the lowest breeze setting because I got a bit chilly. It is quiet and strong on all settings.I don't have a use for the flashlight feature yet, but I could see it being very handy if used while camping. I also chose this model because of the hole at the top that a hook could be put through to hang it. I think it would work great inside a tent once charged up with the battery.I've only had it for a day but everything worked perfectly straight from the box. It's made my work day much more pleasant.Fortunately, it did fit my cellphone adapter - as I happen not to have an USB port on my keyboard. Otherwise, it is a nice little fan which I ran for four hours (twice) at a low speed without the motor slowing down. Both times after I did it, it took just about an hour to recharge it. Unfortunately, it does not tilt, but for the price and the amount of the air it circulates (I found it to be absolutely sufficient at a low speed) - can not beat it! Highly recommend for the table-top usages in the areas with limited ventilation.Very powerful little fan. Surprising output for such a small footprint. Has 3 speeds (low,med,high). High is much more powerful than medium, in fact, it has a little trouble staying in one spot on high and can get tipsy. I put it on a non slip surface and it stays put. The little light can only be turned on if the fan is not running, which is no big deal. I use an Orbtronic (Panasonic) 18650 protected lithium battery in this fan rather than the battery that it came with. I trimmed the spring down so that it would fit, as it is a bit longer than the unprotected 18650s. It works great. I use it in close quarters in the house for noise and some breeze in my face, and also in our tent. I love this fan, paid full price for it, and highly recommend.I Love this fan!!! I was going on a trip and it was important to me to have a really good fan that would work while not plugged in. I found 2 on Amazon. I bought 2 of a different one which I thought I would like better.. And one of this one. When they came this one was BY FAR the best!!! I had to order a second one asap to have 2 of these to take with me on my trip!!! I didn't even take the other one.It's very small but very powerful!! It's relatively quiet and the battery lasts a long time on low or medium!!At my house I sleep with my AC at 67 as I have hot flashes all night!! Going camping for several weeks in Costa Rica I was so scared I wouldn't be able to sleep!! With these fans I did fine!! Great product!!You NEED these! "They are so cool" we're the first words that came out of my mouth when I turned them on. I had thought they were going to be bigger and was disappointed at first glance but WOW! I bought these so that I make some Redneck Portable A/Cs for my kid's Cross Country meets. They come with a rechargeable battery and USB adapter. They have 3 speeds and put out a decent amount of wind on the lowest setting. They have a tiny little flashlight on the end too. The highest setting is awesome. Don't let the size fool you. They are awesome. I'm thinking about buying several more. I love them.Update: the price has increased since I purchased these a couple of weeks ago. They are great little fans.This fan is awesome ! I received this fan the other day and decided to use it this weekend. I was going to the beach and working in the back yard so I thought these would be good places to try it.To my surprise, the fan was great ! Its output is strong and really did comfort me. The battery lasted a long time. Two hours at the beach and an hour and a half at home, then needed to be recharged.I intend on bringing it to work and keep it on my desk.The only thing it is missing is some rubber on the base to keep it from moving while it's on.Great little fan - 3 speeds and a LED light on it. Can't beat is for $13.My only compliant - and it may have been my fault. I thought I had fully charged the device (it was green). We used this through the night camping and it died somewhere between 2AM-4AM. While this could have been my fault - the battery life seemed short. Not ideal if you need it to run for an entire night or multiple nights.I got this for a small bathroom with no ventilation. When you close the door to do "your business," the room can get rather stifling. I don't have a lot of space in that room so needed something small yet effective. This fit the bill just fine and many of my guests have thanked me for it. I also like the fact that it has a rechargeable battery. For its size, it's surprisingly powerful, creating nice cooling.
