O2COOL 5-inch Portable USB or Electric Fan in Black and Gray Review

I've stayed in quite a few hotel rooms where there isn't a constant noise that drowns out all other noise. Well, this little fan does that for me and provides a nice breeze at night. You'll need to buy a USB/plug adapter so you can plug it into the wall, but it's not an expensive device.

Perfect for what I need. I wanted a fan small enough to fit in my bathroom while getting ready in the mornings on hot days. It's a small but efficient electric fan that keeps me cool and is pretty quiet. It's also adjustable to direct the air where you want it. Definitely recommend.

This worked great on our cruise. I have to have my fan when I sleep. I wish it was a little stronger but for the price and size it was great. It is very compact, so perfect for traveling.

I love this little thing! I rely heavily on a fan to sleep at night. It's a mix of noise and airflow. I travel about every 2 months which usually involves flying. The lack of a fan usually keeps me up at night. I found this little guy and he's perfect! Small enough for me to carry around, the bung usually suffices, throws just the right amount of air for me, can be a bit noisy but I can easily adapt. I just leave it at home in my hand luggage and take it out when I'm in the right place. Serious

Great little USB car fan. I bought two and attached them to the 3rd row window with clear 3M double sided tape. Both fans were connected to a RAVPower 2680 battery pack and only used 50% for a week of travel with a minimum run time of 7-8 hours per day. The noise level isn't too bad, but it vibrates a lot. The power button is loose and the USB power cable is very thin.

This is the third one I've bought. They are perfect for a desk fan to help with my hot flashes. In the middle of the night I often reach for the one on the bedside table. It's nice knowing my fingers are safe even if I'm doing it in the dark. We also use them when we travel.

I love this fan! It folds up, fits in my pocket, plugs into my laptop's USB port, and delivers a gentle breeze and some white noise. The cord can be wrapped into a pleated fan at the back, and the elastic band keeps it tidy. As a frequent traveler and street fighter, I'm very glad I found this fan! It's really a lot more fun to work anywhere/anywhere.

a fan the size of my palm (I have big hands for a girl). has only one speed, and the footprint is the same as that of the fan. The cable is removed from the fan. Supplied with socket. I will most likely use it as a travel fan as the fan speed is faster than I would like on my desktop. (speed is probably a bit above average for desktop fans, but not as fast as fast)

I bought the same fan over a year ago and it has become my workhorse to cool my laptop CPU and GPU. When my computer was under heavy load, it would overheat and shut down several times a day. Under idle conditions, the GPU ran hotter than was assumed for sure (>60 degrees C). When stress testing a graphics card (GPU) in the middle of the test, the temperature of the GPU rises sharply until it exceeds 100 degrees C (212 degrees Fahrenheit), after which the computer shuts down to prevent the…
