O2COOLTreva 10-Inch Portable Desktop Air Circulation Battery Fan - 2 Cooling Speeds

I bought the double pack of 10’ and one 5’. Both sizes provide a surprisingly powerful air flow, plugged in and on alkaline batteries. They are very quiet, similar to a white noise machine. The 5” only takes batteries, so I ran it on high for 4 days, all day and night, without having to change the batteries. I spent weeks researching, with exception of tiny handheld fans, every fan I found only takes rechargeable batteries! If your power is out for weeks, how are you supposed to recharge any type of battery???? I have lived on the Gulf for my entire 52 two years of life. Through three major hurricanes, tropical storms, and random blackouts in the hottest parts of the year. I wish I had these earlier.

Almost silent, two stage fans. A good buy for a little extra air movement.

I like the quietness of the fan, perfect size for the space I have available.

We bought for emergency use after an extended power outage in hot weather. They are compact but move the air quite well. Like that they run on battery or electric current. They are going in our emergency cabinet for future power outage.

Preparing for hurricane season in FL. They take a lot of batteries but they work perfectly. Will just need to keep batteries on hand. Like the price for two. Quiet and puts out a nice breeze. Didn't rate the battery life since we aren't really using them...and hope we never have to!

Portability and versatility. Can be used with batteries or with the adapter which is great.

Received 2 in a pack. One works great. But it was a present months ahead of time. So when the present was open it was too late according to Amazon to return. One worked part time. I tried to notify the company that makes them and they refused to fix or replace it because I bought it on Amazon. Amazon told me it's too late to return. SO I am stuck with a bad fan. But so far the good one still works.

Good output seem well made
