O2COOL Battery Operated Adapter Graphite Review

I bought this for an emergency and of course had to use it during Hurricane Irma. My power went out for a week. I ran this fan about 16 hours a day and ran it on low speed (to save batteries) for 4 days before I had to replace the batteries. I don't know of any other fan that is as effective!

What a disappointment. Hurricane Delta is coming so I pulled out my supplies to be ready for the power outage. I took a new fan out of a new box and put in 6 new Duracell D batteries but it doesn't work. I changed the batteries just to be safe and it still doesn't work. I plugged in the power supply and the fan worked, but the whole point of buying this fan was to turn off the power. A very embarrassing waste of money.

Better than expected. It's powerful to suck a small fan. Very quiet. This is the perfect size for a countertop, table or bedside table. I was looking for a battery powered fan to use during power outages (we have lots of these here in Connecticut during hurricane season - most recently we were out for six days during a heat wave). You can also plug it in and store the batteries for an emergency or camping, etc. I love it so much I plan to buy another one for work!

I am currently having a power outage due to work being done outside of my home. But I'm fine because I have this little fan. Just a note buyers. Be careful with your batteries. DO NOT leave them in the fan when not in use. I only use this fan in emergencies. When not in use, I take out the batteries and store them right away in a separate box. Your batteries last longer and are not at risk of corrosion! This fan is perfect for what I need it for. Thank you!

We really like this fan and would like to buy it earlier. It's a lot more powerful than we thought a battery fan could be. It actually blows out some air and makes quite a bit of noise (those who need to sleep with a fan might like this). I love that you can power it from the AC adapter when auxiliary power is available. It only comes with a household power cord, but we have a 9v adapter that plugs into the cigarette lighter and works great with that too. We used it on our boat this summer to…

I have used both of these older generation fans while camping in 105 degree heat and high humidity. They were like an air conditioner. I just upgraded to this new version and I am very satisfied. The fan is relatively quiet at low or high speed and doesn't have the high-pitched whine that the older version had. As mentioned, the fan was powered by an outlet, but not by batteries. The solution was to switch to Duracell batteries. Energizer batteries have a slightly thinner lead on the positive…

This fan saved me. I worked as a postcard seller for American Greetings, so I worked in different stores laying out postcards and keeping the shelves organized. Long story short, many of these stores were VERY WARM inside with minimal air conditioning and I was sweating profusely. There is no way to connect anything. So I bought this fan, got some big clips to attach it to my cart of boxes, and left it on all the time while I worked. The other workers in the shops I worked in were also jealous…

O2COOL CHICAGO SUPPORT WILL NOT CALL YOU BACK! When you call the company you get a voicemail straight away and no one ever calls you back! I emailed their support team, no one ever emailed me back! I have no idea how to put the batteries in properly. There is a large distance between each battery, so the product does not work. O2COOL must post the video and write the web address directly on the box. Videos must show assembly instructions, operating instructions, care instructions and answers to
