Good little fan

It’s a pretty good little fan, and I’ve got no complaints for the $20 price. A very necessary item for camping or hiking during hot and humid summer days, when you can’t always count on a breeze when you want it. Also makes a rather quiet and conveniently sized fan around your home, car, or office (I’ve often been annoyed that 120V box fans are so loud, even on their LOW setting). And an important bit of emergency preparedness, providing just a little bit of airflow and cooling in event of grid power failing during hot summer days (hope you’ve got LOTS of fully-charged D batteries lying around, or a spare car battery!).

This fan is far more better than other battery ones!!

This item I bought a while ago for 17 or 18 dollars and now it’s extremely high that I cannot afford to purchase it again. I was looking into buy it to send it to my mom in puerto rico since they don’t have any power because of Hurricane maria. The fan is battery operated. And i love it and it a perfect size. I recommend this fan to anyone but it’s a little to much money.

Very nice fan

This fan is outstanding. It moves plenty of air and having dual power makes it extra useful. I like the design and quality of O2COOL fans and own several types.

It does have a useful external power inlet

I was expecting more air-movement for the size increase over the 5in O2Cool Portable fan — but I’d say it is maybe only 15-20% more. It does have a useful external power inlet, but otherwise the 5in fan is a btter choice for the dollars to air flow ratio.

O2Cool is Oh So Cool…..love it!

Best fan ever! I’ve been using it for several months…it’s portability and strength is well worth the money. I haven’t used batteries with it, so I cannot speak for how long they last; I have just used it where I can plug it in (on my deck, on my night stand at night, etc.) and it does the job! Quiet (a very soft ‘humming’ fan noise), powerful, cooling, and lightweight enough to move around from room to room with ease. I actually ordered another one just to have an extra in our house!

I take them camping for the tent and works great. Then when the power goes out

I had bought 1 from Target 2 years ago. Couldn’t find them this year. I take them camping for the tent and works great. Then when the power goes out ,I use them then. Love it.

Good But A Little Noisy

I bought this fan as a replacement for one that stopped working after a week of sporadic use. Because my computer sits in front of a heater vent, the monitor was always in danger of overheating and I needed a small fan to put behind it. The last one was a bit smaller and though it put out enough cool air, it didn’t take long for it to burn out. So far this one is doing the trick. It’s a little larger and puts out quite a bit of air for its size. The problem is that it also puts out quite a bit of noise. I wouldn’t expect it to be completely silent and on low it’s fairly quiet. But when the furnace kicks on sometimes it needs to run on high and it has developed a squeaky rattle. Since I usually wear a headset when using the computer, I can stand the noise – although I can still hear it. Without the headset, the noise can be very distracting and sometimes irritating. I’m not sure if it’s just this particular model or if I just happened to get a noisy one. It works very well for what I need, but I’m not sure I’d recommend it to someone who is looking for a quiet fan.

Quality item

Works great. Storm knocked out power in our area for awhile and the battery-operated feature of this fan worked very well. Just the right size, too.
