Review: O2COOL Treva Fan: Small but Fierce Breeze Boss - So, the O2COOL Treva 5 Inch Battery Powered Fan claims to be portable with 2 cooling speeds — which sounds like the perfect sidekick for surviving your office’s questionable AC decisions or your “I forgot to open the window” moments. Does it work? Remarkably well. Like, “I swear I’m in a tropical breeze commercial” well. It’s tiny, but don’t let that fool you — this thing packs a punch. Two speeds mean you can choose between a gentle “ahh” and a full-on “I’m blasting a hurricane” mode. Perfect for when you want to subtly cool off or announce to the room that yes, it is that hot. Battery powered means no awkward cord tangles or hunting for the nearest outlet like a caffeinated squirrel. Just pop in the batteries, turn it on, and bask in your personal wind tunnel. Pros: Surprisingly powerful for its size — like a pocket-sized wind machine. Two speeds let you control your breeze level, from “nice breeze” to “hold onto your hat.” Battery powered and portable, so you can bring it anywhere — including your desk, picnic, or that desert island you’re dreaming of. Cons: Batteries not included, so prepare for a scavenger hunt or emergency run to the store. Not quite strong enough to blow papers off your desk, but close enough to make you paranoid. Might cause coworkers to envy your personal breeze zone (or secretly plot to steal it). Final Verdict: ⭐️⭐️⭐️⭐️⭐️ – 5 stars. Small, portable, and blows away the competition — literally. If you need a breeze buddy that won’t judge your sweaty existence, this is it.
Review: O2COOL IS COOL - 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 desertcart 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 desertcart 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.

## Questions & Answers

**Q: What is the battery life at high and low speeds?  Thanks.**
A: I just got 3 of these on a hot summer day. Although I have AC, I don't push it hard to save on the electric, so use fans to help make the AC feel a little cooler, & circulate some of the cool air to the bathroom. I also couldn't find a fan that would fit in my tiny bathroom window. These fit perfectly. I immediately tested them out. My "D" cell rechargeable Tenergy batteries were purchase around 2002-2003. They were old, well used & through a fire so suffered severe heat & steam. Rated at 10ah (10,000 mah), I'm sure as old as they are, they're only half the the power of their original new Ah rating... probably worse. Rechargeable batteries deliver almost constant current until they're just about fully discharged. So I expected full speed from the fans until the batteries were almost wore out, & that's what I got. On my very old worn rechargeable "D" cells, all 3 fans ran at full speed on high with no change for 23 hours. By 24 hours they had slowed down to about the speed they would be on the low speed with fresh batteries. By 25 hours they slowed down so much that I could only feel a breeze by putting them close to my face. So on my very old batteries who's life expectancy was exceeded many years ago, I got 24 hours of useful continuous breeze. Some say they can't feel a breeze unless they're within a foot or 2 from it. Not true. They're either using some pretty bad or worn out batteries, or got a defective one. Placed just outside my bathroom door to circulate some of the cool AC air into the bathroom, I could comfortably feel a breeze from the toilet 6 feet away. But beware this thing probably only draws a watt or less. It will not blow as hard as a 35-150 fan. It's a small portable device that will provide a mild breeze, but not from across the room. In shorts & a T-shirt it definitely felt good from as much as 6 feet away for 24 hours.

**Q: is there a way to make it blow cold air without dripping water on it?**
A: I'm pretty sure you were thinking of those condenser fans (?) that use water by creating a fine mist and as it blows air it has the ability to cool the area by 15+ degrees. Its not a dumb question. Try a personal mister in front of it (mist being directed towards you not the fan) and that will feel much cooler. That's how humans cool down, moisture (sweat)...air...
Ice in front of a fan can in fact drop the temp of the air traveling over it but you have to be close to the source or the air gets warmed again by time it reaches you.  As far as the product goes....o2cool fans are great! Best wishes

**Q: Is there an adapter that can be purchased for the 02COOL 5" Fan?**
A: Its a DC 5521 plug also the older model does have the dc plug I'm not sure if there is one without exactly. This is the plug I use to run the fan off a portable charger https://www.amazon.com/dp/B07J6NQ1KN/ref=cm_sw_r_u_apa_fab_AoPGFbC78RXG7

**Q: Is there a way to rig this for use as a tent ceiling fan?**
A: Being a tent camper and a person who likes to make things work, I would say yes, you could. It would probably have to be hung upside down with a heavy grade string or a small rope around where the battery housing connects to the fan part. I hope this idea helps.
