🌬️ O2 Cool Fan: Versatile 8 inch Portable Fan with AC Adapter - Battery or Electric Operated for Indoor and Outdoor Use, 90 Degree Tilt Feature Review

This product saved my life during Hurricane Irma! When we had a power outage I quickly turned on the fan and was able to sleep well in these tense blustery conditions! Thank you!

Fully operational - even with new batteries (tested in our tests) and mains adapter. I have about two dozen O2Cool fans - for the house, for the van, as gifts, and this is the first of the ones that were on Dead on Arrival. The plastic frame seems thinner than the others. I've never ordered rounds. going back.

The fan is lightweight which is good for traveling. But after adding batteries, it's hard! This will provide some air movement, but not as much. The switch on the side is very sensitive. I had a fan in my suitcase and it came on while driving and drained the battery. The battery compartment is locked with a tiny screw, you need to have a screwdriver with you or you risk losing battery power.

I love these little fans! Enough power for a desktop computer or TV from a few feet away, so quiet you won't even notice! I didn't think my former O2Cool fans could be beat, but they do! (PS The only reason I had to replace them was because I dropped them which caused the motor housing to come loose and make it rumble. They have a different housing so I don't think I'll have the same problem but I try not to drop them!

The only thing I don't like about this product is that it's made of lightweight plastic and feels cheap. Otherwise it is SUPER quiet and produces more wind than I would have expected from such a small and thin fan. I've got over 40 hours and counting (on low fan speed) from a set of slightly used batteries. I wish I had this fan right after the hurricane when I really needed it, but at least I'll be ready next time we lose the AC.

Looks nice, makes a pretty good breeze for its size and seems quiet. One complaint is that you need a screwdriver to open the battery door, which is poor design. Also, the batteries were very tight and difficult to remove. Unfortunately I had to return it as the outside of the switch on the unit I received was broken (I had to poke in the slot with this screwdriver to turn it on). So can't say anything about long-term use. The season I need this is over so I haven't reordered, might try it on…

Batteries just received and installed. I didn't expect the air outlet to be very strong, but I am very surprised that when using batteries whose name is NO Air, the stronger airflow actually comes from the back of the fan and not from the front as on the Photos shown where it's "o2cool. Then when using AC everything is fine - good strong airflow. Update: I believe the fan blades spin backwards when using batteries - or only very weak with batteries but they should be fresh As they came from…

Looking for a quiet fan to circulate the air in my home office. I have another O2Cool fan that runs on batteries only and the hinge is a bit loose (can't tighten it) so sometimes it falls off. Otherwise I liked this fan so had high hopes for these given its similar (slightly larger) size, 3 speeds and AC power. I really wanted to like this fan. Unfortunately: 1) This fan is significantly noisier than the previous O2Cool fan - in my opinion this fan really needs to run at a much lower speed to…
