O2COOL 5 Inch Portable USB Desk Fan with Rechargeable Battery - Personal Cooling Fan for Office, Home, Travel & Outdoor Activities

Best portable fan yet! And this is the THIRD one I've tried. This fan is pretty powerful, but obviously not as powerful as a huge, regular sized fan. I'm a Registered Nurse and I do a lot of running around and heavy lifting on the job. I tend to get really sweaty at work when I'm running around. When I go to chart, I plug this fan in, and it cools me down! It's not loud. I love that it can be adjusted up or down. The fact that I can plug it right into the computer is great, since there aren't always plugs available where I am sitting, but there is almost always a free USB port.It is the best made portable fans I've used. The others all broke within a couple of weeks of use. Basically, the other fans I bought would have a loose part near where the cord plugged into it, which would always end up breaking, or they barely generated any air flow. This one seems very sturdy. I've had it for about a year, and I use it every single day that I work. I pack it up and put it in my bag at the end of my shift, and take it out of my bag and plug it in at the beginning. So it gets quite a bit of wear and tear, and transport.Another awesome feature is the USB port plug. I've tried battery operated fans and those run out of batteries constantly, or they air flow they generate doesn't do anything hardly. I've had multiple co-workers ask me where I bought this fan and how they can get one. The price is incredibly affordable, making this a steal of a deal considering how well it works. It comes in multiple colors. It does come with an adapter to plug the USB into an actual outlet, but I usually just plug it into the computer.I can't say enough good things about this fan! I would definitely recommend to a friend, and would absolutely purchase again.O2COOL 5" Portable USB or Electric Fan, Blue
