  • Works well.
Color: Black Size: 1 Unit
Please understand this is a small fan so don’t expect it to cool down a large space. It does cool down a small space adequately. I used it to cool my face down while outside on a hot and humid day cleaning my horse tack. It made a difference in my comfort level for the better. It’s portable, battery powered & sits upright in a level place. ... show more

  • O2COOL IS COOL
Color: Black Size: 2 Units
It was July 31st, 2019, my family and I were in Brooklyn, New York visiting my grandparents. We realized it was easier to fly there since it is a fourteen-hour drive from Georgia to New York. We figured we did not need to rent a car because we were either going to uber or drive my grandfather’s car (which is a 1998 Honda Accord). One afternoon we decided to go shopping, we got into my grandfather's car and we became aware that the AC was not working, keep in mind that it is ninety degrees outside. The mall was only ten minutes away, so we decided to go anyways. We sure regretted that, instead of taking ten minutes it took us about twenty-five because of New York’s traffic. At the end of the car ride we were all sweaty, uncomfortable, and never wanted to get back in that car. Because I am a genius, I went on Amazon and purchased a portable fan. It was a great purchase because the shipping was fast, affordable, the description was accurate, and the quality and functionality was great. I ordered two portable fans for $16.99 on July 31st and it arrived on August 2nd. We were lucky that the shipping was fast because we used that fan for the other five days that we were on vacation. Seventeen dollars can seem like a lot of money; however, I feel like we got our money's worth from those fans. If you think about it, we basically paid seventeen dollars for AC in the car. We also used the fans in my grandparents' house, which was also hot since they do not have central air. The size of the fan was also true to size. They were the perfect size, small enough to where we could hold and carry them and big enough for us to feel the air blowing. Unlike some other products you buy from Amazon the portable fans description was accurate. It said how it was perfect for both inside and outside, which was true because when we used the fan in and outside it worked great. It being portable was also accurate to description because the fans were light and small enough to carry around. They also did not try and hide the fact that the two d-cell batteries that are needed for the fans to work are not included. The quality and functionality were also great in this product. The fans had two different settings which was nice because it allowed us to be in control. Some people might think for seventeen dollars that the fans quality might not be good, but to us they worked great. They are made from good material and the air that blows from it is strong. In conclusion, I give the portable fans 5 stars. It really made our trip in New York better; we did not have to be sweaty and uncomfortable in my grandparent's car and house. The price of the fans is totally worth $16.99. The shipping was fast, the package only took two days to arrive and we were able to use it as soon as we got it. The description was accurate because the fans were portable, they had different settings, and they did not include the two d-cell batteries. The quality and functionality were also great. The fans cooled us down and they never stopped working. If you are looking to buy two good portable fans that are not super expensive, I believe that this item is for you. You will truly be satisfied and not regret buying these fans. ... show more

  • Great portable fan - puts out a nice flow of air
Color: Grey Size: 1 Unit
We often go to events a our local multi-purpose building and the old water cooler really doesn't do a very good job of cooling the building. We sit at round tables and I would always have a hand held paper fan trying to cool myself. I got on Amazon and found this fan that runs on batteries. I was skeptical as I didn't think it would put out much air but this little fan amazes me and it does the job. There are two speeds and it's super quiet. Great find! ... show more

Color: Grey Size: 1 Unit
I like these, but people should be aware these are not for continuous use for many hours every day, all summer long or the motor will wear out. These do not have DC or AC brushless motors like found in computer fans, equipment, or a brushless AC fans like window fans have. These have motors with armature contact brushes inside like most cordless tools, vacuum cleaners, toy cars, & drones have. If you ran those most of the day, every day, for months, their motors would wear out too. These are for occasional use where power isn't available or convenient -- like during camping trips, fishing, stuck in traffic without AC, keeping cool on the hottest part of the hottest days, or during a power failures on hot days. If you plan on using this as your primary daily personal space fan for a whole summer, plan on buying another when it wears out... they don't cost much when on sale, so maybe stock up on a few spares if no AC power is available & these are your only option. If AC power is available, use an AC powered fans with a brushless motor to get one that will last for continuous long-term use. Or get the more sophisticated & much more expensive battery operated fans that use computer-like fans with brushless motors if no power is available & you need to run a fan daily for hours. These are great for camping trips. At my age & condition heat can kill me, so I also like them to keep cool during power outages. I do keep one at my desk to cool down occasionally but not for all day & daily. At this small size, low battery consumption, & low price, they do not blow hard. They do provide a fair mild breeze if placed nearby. It's a personal fan, but couple people sitting near it will feel it. It is not a window fan. It will not cool down a whole room, tent or apartment when placed in a window, but if you have no power, it is an improvement over nothing at all. If you need something more powerful, it will cost more, & if run on batteries, consume more batteries faster. More wind requires more power/batteries. I did a run-time test on these by putting AA size Tenergy rechargeable batteries in a "D" cell adapter enclosure, & used them in the fan. It ran it on 2 AA batteries (not D cells). It ran 8 hours before I noticed the fan was starting to run slower. By 10 hours it had slowed down to as fast as setting it on low with fresh batteries. By 11 hours, although it was still spinning, it wasn't enough to feel any breeze from it anymore. D cells have about 3 times the power & run-time of AA batteries. So you will get a very long run-time. My window AC unit never circulates enough cool air all the way to the bathroom. So it's always very hot in there. Don't want to open the bathroom window to let the hot, humid swampy air in. I place this fan in the bathroom doorway blowing in, & I can feel fair breeze from the toilet 5 feet away. I understood these don't blow hard but have a very long run time. So I bought 3 to keep cool enough camping or during power failures, & as spares if I wear one out (I use one at my desk occasionally because it takes up little space & is so portable). Use it for the right purpose! It is not for continuous use all day, every day, for a whole summer. It's a personal fan for occasional or emergency use. I probably would have gave it 5 stars if they warned people not to use it continuously daily. I was aware of what I was getting, but others may not be. ... show more

  • nice little battery operated fan
Color: Black Size: 1 Unit
Our apartment community recently had a planned 14 hour outage. I bought this fan and it worked well enough to keep me comfortable. Uses two D batteries. Is adjustable but does not go side to side. Air flow is fine for a small fan. Noise is minimal. Seems quite durable. I'd buy this again.
