I can take it to my office to keep cool while I work and also when I go to bed on a warm night, I can have a good night's sleep running the unit without concern of noise because the unit runs very quietly and can easily run it for at least 8 hours per charge without having to find an outlet to connect to. One last thing the unit is also a humidifier you can add water at the top of the unit and will provide a comfortable level of humidity with a mood setting and soft color lights. I highly recommend this

I tend to run hot and my coworkers that share an office with me are always cold, so this helps me stay cool at work. It is quiet so noise is not disruptive and because of the design, it doesn't blow air into my phone so that I sound like I am in a wind tunnel.
