Review on XPOWER FC-150B Portable High Velocity AC/DC Dual Power Operated Portable Rechargeable Battery 18,200MAh Utility Fan, Extended Air Flow, 1000 CFM by Dawn Bias

I'm something of a fan nut, and I own quite a few. Small fans for desktop/workbench, HUGE fans for my shop, carpet fans, floor fans.you name it and I've probably bought one.But THIS is something entirely different! On the lowest setting it is quiet enough to speak over in a normal voice, while somehow creating airflow through an entire room. The second speed is about twice as loud, but it's well built so there isn't any squeaking or rattling, just a good solid hum. The third speed is comparable to fans two or three times this size on their max setting. You're not going to talk over the 3rd speed, and at this point you're going to need to make sure everything is firmly held down on tabletops. If you have any paper or trash laying around, you'll quickly find it!And then there is the 4th speed setting. Have you ever pulled out into the street and realized that the oncoming car was moving faster than you thought, so you slam your foot to the floor and push that 1993 Lumina to the max? Yeah, so, imagine doing that, but instead of a Chevy Lumina, you're being dragged behind the chariot of Zeus as he races against the Sun in a contest to dominate the sky. The roar is like that of a jet engine at full blast into a bullhorn. The wind produced by this can strip paint off of your car, while it is still parked outside. I was nearly blown off my bed when I used this for the first time. Some even believe that one of these being left on "4" is what caused Hurricane Ike in 2008. I'm still trying to find my dog, but from the puppy shaped hole in my brick wall, I'm pretty sure he is living out his dream of being the first dogo on the Moon.If you need a fan that will gently stir the air, but has the power to deforest half of Virginia, look no further.
