Got this to help with keeping the airflow going in my smaller office loft in my apartment as the minisplit system does not cool the area and the small windows upstairs do not provide enough air. So far this has been great and at full speed moves a LOT of air. The fact that it is wireless and chargable is such a plus as well so i dont need another plug or extension cord to make this work. It also charges to full capacity relatively quickly - i have not had to recharge since having it so im not too sure on the extent of its power but it is definitely a good length of time. It is light and easy to move and quickly adjust the speed you want to go. Of course, the max speed is affected by the amount of battery so keep that in mind if you really need something to go max at all times. Im waiting on summer to see if this can pull off what i need to keep temps down in an otherwise super stuffy space with a pc, lights, etc. running in 80degree weather.
