A power outage in the height of Texas summer is just about the worst thing that can happen. During one that lasted several hours, I ended up driving across town and taking my elderly dog shopping, just to get her inside somewhere that had a/c. More recently, we've had some short power outages, lasting maybe an hour each. Still, that's enough time for my apartment to go from slightly-warmer-than-I'd-like to my-living-room-is-a-burning-hell. Looking for a back-up plan, I decided to see if battery operated fans were even a thing, and that's when I found this O2Cool fan. I was a little nervous about buying it, since a few reviewers said theirs didn't work or didn't last, but a few reviews from hurricane areas had me wanting to give it a try. So I ordered one and crossed my fingers. TL;DR: Awesome fan, works great! First off, I like the size and design. This isn't one of those tiny palm-sized USB fans; it's about a foot wide in total, with a 10" span inside for the actual fan blades. It's slightly taller than it is wide, but it's depth is pretty compact. The vented cover is sized just right for me to not accidentally slip a finger inside when I pick it up, though it does have a carrying handle if you want to play it really safe. It does come with an A/C adapter, which I guess is nice, but I don't really need. Then again, it may come in handy if one of my two regular fans goes out and I need a temporary replacement. It's kind of a battery hog in that it needs 6 D-batteries to run, but honestly, I think that's a good thing. Any less, and it'd be a much smaller, weaker fan that wouldn't last any time at all. I haven't had occasion to run it for hours and hours and hours, but according to other customers, it lasts 9+ hours on high and even longer on low. I think that will be plenty to get me through the next power outage. And about those low and high speeds... This thing has great air flow. I wouldn't want to set it up 10 feet away from me, but since it's not tied to a cord or outlet, that won't be a problem. On low speed, there's plenty of air flow, and on high speed, it's awesome. It's slightly less powerful than the 22" corded turbo fans I use on a daily basis. All in all, I'd say this is an awesome buy. I was impressed enough with the first one that I immediately ordered a second, and both work very well with both the A/C adapter and batteries. I'm stocked up on D batteries now, too, so it looks like I'm set to ride out the next power outage in comfort! Update 12/1/2108: I bought two of these fans to get me through a power outage, which hasn't happened yet. But a few weeks ago, my apartment's a/c went out in the middle of the night, and the two fans I brought into the bedroom just weren't enough. I ended up grabbing one of these battery operated fans, intending to use the included A/C cord, and set it up on my nightstand. But in my sleepy, overheated stupor, I turned it on and quickly fell asleep -- forgetting to plug it in. Six hours later, I woke up and called maintenance, and they had my a/c fixed fast. Then I went to unplug and put away this fan, only to realize I'd left it running on high for 6 hours on nothing but battery power! So yes, I can now say without a doubt that these little fans run great for at least several hours. Update: Here I am. Power outage. Texas. Summer. While my neighbors sit in their doorways trying to catch a weak breeze, my dog and I are comfortably lounging on the sofa, a fan trained on each of us, while she sleeps and I read my Kindle. This is EXACTLY the scenario I wanted to be prepared for, and these fans are everything I'd hoped for!

I have been using this fan since December 2014 and it has been perfect. I originally bought this fan to use in my dorm because last semsester (fall 2014) the ac in my (low cost / old) dorm stopped blowing cool/cold air. It only blew out very hot air. I was left to the mercy of the university to send someone out to fix since we are not allowed to mess with at all. That person never came so rather than allow the hot air to blow and bake me to death, I just had to completely shut it off ( my dorm still uses individual ac units that are attached to the windows lol ) but doing so just leaves the air very stuffy and basically zero circulation in my room. That's why I bought this, sorry if it is too much but I feel it demonstrates what I was looking for in a fan when I went shopping on amazon for one. here are the pro's and cons pros: Size is perfect for sitting on a desktop in the corner. I can set it in the corner and be able to utilize my desktop for either my laptop or for Home Work. To my amazement this little fan blows air very well. It has two settings for how hard it blows air. the lowest is usually enough for me since I have facing towards my face on my desktop but even on the highest I don't get that feeling of being smacked in the face by the air. It isn't "weak" but it isn't powerful like an industrial fan. If need a heavy duty fan then buy an industrial one. I obviously don't need such a large fan in my dorm and doubt it would even be allowed. Fairly quiet and sound isn't annoying. I find it soothing when my dorm room is completely silent. I use the adapter and don't really use the batteries because I leave it on almost all day 24/7. So I am able to tell you how long it lasts on batteries but it requires 4 D batteries so it should last a decent amount. Cons: none will keep review updated on status on my fan or if it ever "goes out". The price on this is very reasonable. I didn't want a complicated / high-tech fan that had tons of settings. I just wanted something simple but functional and durable. Looking at the reviews on amazon I decided this O2COOL fan W/adapter was just what I was looking for.

Had one of these that lasted five years in rough conditions. Ordered two more. Some tips: make sure the fan is in the off (middle) position when you put in the batteries or power cord, click the power cord in all the way, and be sure you have fresh batteries. Love the portability, power options, and wind power of this fan. Love how sleek it is, too. Takes up very little room.

So I rounded down on this one. It's between a 4 and 4.5. I bought it so I'd have a fan to put in the window that would blow fresh air toward my bed, without blowing it directly on my face. It's a delicate balancing act. Anyway, the fan fits perfectly on our sill, and the cord was *just* long enough to plug in. The fan has two settings, low and high. Low setting isn't getting enough power, I think? It cuts in and out. Hard to sleep when the motor keeps slowing down, almost dying, then speeding back up. High power works fine, but it's not very powerful. It's spinning its little heart out, making a good drowning-all-other-noises racket, but it's not pulling a whole lot of air in. I can imagine this would be perfect for a smaller space, like a camper or a little cabin. But it's not doing much to cool down my medium-sized bedroom. On the other hand, it reduces the noise of the dogs barking next door. On the other, other hand, the reason the barking is so loud is because I have the window open. Bottom line: if I'm sitting right next to the fan on the computer, it provides a nice air flow. A few feet away on the bed, not so effective.
