My RV is without house power, so my fantastic in roof fan runs off my engine battery. This worries me enough that I just wont let it run long. So I purchased this hoping it would move enough air to help me cool off enough to sleep. It does, even on low and even 21/2 feet away. It's very quiet too. I ran it for over 6 hours last night and it still has power. Seems to be made well. Last but not least, it's so darn cute!

I was looking for a small fan I could take with me when I travel to Europe. European hotels do not have very good air conditioning, and very few hotels have windows you can open. Sleeping at night can be hot and uncomfortable. Since Europe power is 220 volt, purchasing a US 110 volt fan would not work. I could purchase a 220 volt fan, but I do not travel to Europe that much, so that is a waste. I could purchase a US 110 volt fan, and a 220 volt to 110 volt converter, but I have no other use for the converter. Also the 220 volt to 110 volt converters can be expensive, big, and heavy. This fan fixed all that. It is a 5 volt DC fan. Power is either via the included removable/rechargeable Lithium battery, or you run/charge it via the included 40 inch USB cable (Type A to Mini-B). You either plug the fan into the USB port on your laptop computer, or purchase a $5 USB charging cube (which run on 220 volts or 110 volts) like I did. An added bonus is the 2 built in blue "night lights", and a white "flash light" that is on the side. Press the "ON" button once, gives you low speed, twice gives medium speed, three times high speed (see note below), and the 4th time turns off the fan, and turns on the white side light.The fan has plenty of power as far as I am concerned. Running it on medium speed provides a nice breeze. Running on high is very powerful, but also somewhat noisy.A few notes on the fan.1) The removable/replaceable rechargeable battery that is included with the fan, looks like an AA battery, but is a lot bigger (see picture).2) The battery is a Lithium battery, which means it should recharge many many times. Just plug the fan into USB power, and the battery charges. When the charging light changes from "red" to "green", the battery is fully charged.IMPORTANT NOTE: Per TSA regulations, Lithium batteries can NOT be put in CHECKED baggage. This battery has to be carried in your CARRY-ON baggage. So put the fan in you checked baggage if you want, but put the removable battery in your carry-on baggage.3) The fan has 3 speeds, but the high speed setting runs at medium speed if the USB port has power to it. I think this prevents the fan from overloading your USB port on your computer.4) The white side light does not work when the fan is running.5) The blue lights turn on by holding down the "ON" button for a couple seconds when the fan is running on any of it's speeds.

So here are some details for those of you who want it. I used this while camping.On High - Stock battery (Lithium Ion) ran 1 hour 31 minutes. Cutoff voltage was 3.49On High - EBL 3000 mah battery (Lithium Ion) ran 1 hour 37 minutes. Cutoff voltage was 3.57On an external battery pack plugged into USB, high only runs as fast as medium - So here are the results.PNY 7800 mah battery pack ran 7 hours 42 minutes on Medium.Anker 20,000 mah battery pack ran 21 hours 4 minutes on Medium.Conclusion - Buy an external battery pack for use when camping, even on medium it moves a lot of air.

I ordered five of these fans to send to Puerto Rico, after hurricane Maria. My family have called me and given me so many compliments and great feedback about these fans. The fan is small, but it pushes a comfortable amount of air to the user. It is so nice to be able to recharge it via USB! I personally like the design and color. Will recommend buying for camping too. Nice product!

There was no USB cable included with my fan so I used my own because I needed it for Hurricane Irma as we were without power. It will only run on the first two speeds. When you turn it on high, it cuts off. Seeing that it runs, I assume it is a fault with the fan itself and not the battery. So, no cable and it only runs on two speeds. Not what I paid for and now I have to go through the hassle of returning it.Update: This company stands behind their product! Not only did they honor their warranty, they replaced my fan immediately with one that works perfectly. Their customer service is excellent (thank you Gigi!). I have since even ordered another fan as a gift and am planning on at least one more. This little fan has power! I originally ordered it to use during Hurricane Irma. But I'm keeping it out of my hurricane supplies and using it year round in Florida. It's great to have in the bathroom when it's still steamy from taking a shower and you're trying to put makeup on. Or, um, hot flashes! Great product! Looking forward to doing more business with them.

Deceptively powerful desk fan. I just wanted something to circulate air while i was gaming, sometimes a room with multiple pc's/consoles can get warm. I was blown (pun intended) away by this fan. Low and medium settings are decent and super quiet. High does make some fan buzz but not bad, however the air it kicks out at you is amazing. The battery is a nice add on though I can't imagine using it not plugged in, maybe camping? I also set it by my bedside now with my phone on low circulating air in the bedroom. I don't use the backlight, nice touch though. For the price its a win buy. If you're just looking for a small desk fan get it. I don't review stuff much here but I purchase plenty. This item deserved a review.

So i bought this mainly in case the power goes out during Hurricane Irma here in Florida and its hot here so no AC or fans. This thing is tiny but wow it is powerful. it has 3 settings low med and high. Charges via USB. the battery is a "Lithium" very odd type battery. You cant get it at your local store. Would love to have a few extra batteries. (UPDATE 9-12-17) This was a lifesaver during Hurricane Irma. Lost power now for 2 days due to the hurricane. ITs hot here in Florida and this fan works great. Last around 6 hours on medium setting. I recharge it via USB in the car since i have no power right now.

For a battery powered fan, the Opolar F201 gives off a very decent blast of air. One reason for this is the use of the 18650 batteries, these are generally used in Ecigs because they are capable of higher wattage. It is total genius to use them for a fan as you get so much more power than those that use the alcaline batteries.The fan itself is well built, has 3 power settings and it even has a led light!. The fan is noisy most fans are, but in an office or out in the wild you won't notice.Opolar were very helpful in the entire transaction.

It has 3 levels, and level 3 is super strong, you would not believe how much.Still, level 3 usually does not last too long, as the battery drains when you have it in that speed.If connected, mine one at the least, does only run in speeds 1 and 2 (even speed 3 is selected).Anyways, speed 2 is very good.If you sweat at nights, this is a very good companion, and speed 1 or 2 might do the trick just fine.

I bought this fan to keep me cool while sleeping in very hot weather. I set it up to discover that Speed 3, which is very powerful and exactly what I need, doesn't work while the fan is plugged in (only when running on battery which runs out after 1-2 hours). This otherwise very effective fan loses a star for this serious limitation, and loses another star for failing to mention this in the product description.

I loved the portability of this fan and the 3 settings on it controlled by the on button. There is also a handy light on the side which is also controlled by the same on button.I used this during the heat wave at night and got so cool, on setting 1, I had to turn it off then on again a few hours later.It has a quiet but effective fan, which for its size is quiet amazing. I have both a large rotating fan and a column one and it gave both fans a run for their money I even took it to a concert in the park and had the family fighting over it's coolness. On the first setting the internal battery for the fan lasts about 5 hours and less if you use the higher settings.I would definitely recommend this fan!

So far so goodBattery life is goodpower is excellentBought to go on my running machine to try and make the runs feel less stale, definitely worked, the max setting is very strong for it's sizeHas also been used in hospital and on my desk - works great everywhereThe torch is bit odd and kind of just tagged on, but at the same time you don't have to use it
