I received the Opolar 10000mAh 8-Inch ... Fan yesterday and tried it last light, running it on low, plugged in to charge the internal battery in the process. At a distance of about 7í I could not hear the fan (on low) and could feel air movement ó nice and easy to disregard. Neither the sound or air movement would interfere with sleep.

Itís running on battery now. At 3.5í I can just hear the fan above ambient noise. I tilted it up so it blows just over my head ó cool but not irritating. The clip shown acts as a stand if you have a flat surface to set it on. I havenít needed to use the clip.

This was a great suggestion. Thanks Les.
