We live in an area that is prone to storms and that sometimes results in power outages. When that happens in the middle of the night, we often wake up and cannot go back to sleep because it is so hot and so QUIET! We bought this battery operated fan in hopes of making things a bit more tolerable during power outages. So far, this fan has lived up to its advertised potential. I operated the fan on HIGH for about 3½ hours before the battery was drained. It took roughly 2 hours to recharge the battery after that. As for NOISE: we actually like fan noise when we are trying to sleep, so were hoping for MORE noise. I would say the fan makes less noise than the average kitchen oven vent fan. It is a (to me) very soothing noise, yet not so loud that it requires raising your voice to carry on a conversation. As an added bonus, we can take the fan outside to the patio or porch without the need of an electrical outlet. It is light enough that anyone can move it from place to place, and the air flow can be directed vertically by simply tilting the fan in its frame. The fan moves enough air that it covers a 15x12 room adequately. I would recommend this fan to anyone.

There is seriously only 1 thing I hate about this fan. Y Oh cannot remove the faceplate! There is no way to clean the inside of the fan. I have 2 dogs and this fan is on top of a 3.5 foot dresser (not directly taking air in at hog height) and every 2-3 months it gets so caked up with dog hair I had to spend another $60 to get a vacuum/blower crevice tool and it takes about 45 mins - 1 hour to clean the majority of the hair out. I have the smaller yellow version and you can remove the faceplate for easy clean up, so I may invest in a mesh screen to catch it on the back before it is sucked in.

This fan is wonderful for moving from room to room or even packing in the car to have in hotel rooms. It runs very long on a charge and is incredibly quiet.

Bought this fan to take to a music festival I felt to as portable cooling and it delivered. Was there for 5 days and I forgot the charging cord but was able to make it last all 5 days on 1 charge using it on the higher side of medium for cooling at the hottest parts of the day in my tent. Really good air flow and stayed where I pointed it no problems. Even using it on high it wasnt super loud.

works great. Very helpful for a fair sized room. The low speed setting is good at hot nights to cool enough to have a good sleep. Last more than 20 hour when set to low speed. But only about 3 hours at max speed. If it can last long will be perfect

Ive owned this unit for 2 years. Ive charged it fully and drained it fully about 20 times. Ive always left the battery at full charge when not in use . Recently I went to charge the unit from being flat after it only been flat for a day and the unit will no longer turn on or charge. Now it is a $90 paperweight. The unit is built out of metal which allowed it to push plenty of air. While it was working the only complaint I had was that moving the position of the fan in relation to the stand would sometimes cause the holding bolts to disconnect. At full power the fan would last about 3 hours. At half power about 8 hours, and it 30% power it would last a full 24 hours as advertised. I figured that once the battery failed to charge I could still use this fan as a plug-in. I was wrong. I think Ill take it apart and see what makes it tick, now it is no longer working.

Overall, a nice fan with very high airflow. CONS: - Battery is a bit lacking. Only lasted ~4.5hrs on a full charge on high. I would expect about double that on medium, but I havent tested it yet. - While the stand isnt huge, I feel like it could have been smaller, or foldable for this price point. - The knobs to set the angle seem a bit weak and likely to crack over time (thin walled ABS, probably no UV stabilizer). And God help you if you accidentally unscrew one all the way! You practically have to take the whole thing apart just to get the knob back on since the screw holding it falls into the fan cage. - Must be charged via a 12V barrel jack, a USB powerpak wont cut it. PROS: - Very high airflow - BLDC is good quality and I expect it to last for a long time - No bearing noise (although there is some blade noise at higher speeds, but not much) - Seems like the IPX4 rating is appropriate, this thing should last awhile when doing drive-and-tent camping TL;DR - Overall, pretty good. High airflow, but low battery life at max speed. Stand is the weakest part of the whole design. Its obvious the costs went into the battery, motor, and electronics rather than the stand. Which is a good thing.

We bought this fan to take with us on a road trip. Sleeping with a fan (for noise and breeze) at home every night, we know that not having one in our hotel would have resulted in a significant loss of sleep/rest. This fan although not as loud as the one in our bedroom, produced plenty of sound and breeze to ensure a rest as good as the hotel mattress would allow. So far, we have only used it for a few minutes while only the power of the batteries. When unplugging the unit, no slowing was noticed. The size of this fan is perfect for travel. Were it any smaller it would not have produced the desired breeze. Were it any larger, it would have been too large for reasonable luggage. Overall, we are 5-star pleased. If a problem with the durability of the fan - or any unexpected deficiency - should arise within a short time-span, then I will update the review to reflect that.

I ordered this fan 2 weeks ago and I am so pleased with its performance. I live in South Florida and wanted a fan for the back patio since it can get very warm with stagnant air flow. The first time I used it, it turned my patio into an enjoyable summer hang out. On high, it works for almost 6 hours. When I turned it down, I was out all day and it did not reach the end of the charge. I like that the fan level is variable, not just on and off, I cant say how long it takes to recharge because I plug it in and walk away. I also like that it will run when it is plugged into the wall, while it is charging. Thats a nice added feature because I have a blue too speaker that will not play while charging - annoying. There is not a negative thing I can say about this fan!

This fan is cool, and the best battery-powered one I’ve ever used (I have a few). I live off-grid so my power runs out by 2am every night and doesn’t come back on until 8am or later. But this thing charges itself during the day and just keeps on running all night, then recharges itself after the power comes back on usually 6-8 hours later. It keeps the bedroom breezy & cool all night long, isn’t too noisy, and the speed is super adjustable. It’s also lightweight and easy to carry because of the handle, so I often take it with me when I go to art shows/fairs as a way of keeping myself and my clients cool while making & selling artwork under my canopy. It also makes hanging out outdoors more comfortable because it gets so darn hot in the summer, but I just pick a spot in the shade, set this thing next to me, and I can keep cool for hours while reading, painting, etc., and not have to be stuck in-doors next to my swamp cooler. The breeze also helps keep flies off my person and my paintings. The battery lasts for many hours, especially if you keep it on a medium or low setting (rather than a high setting) and though I’ve had it for 2 years now, the battery seems just as good, and the fan is still working perfectly. It’s made of sturdy metal and has handled accidental falls/drops/kicks/etc like a champ.
