SWEETFULL Portable Neck Fan 

I think it works well for cooling when lounging around. I don't think this would cool well if one were to wear it during a workout.

You can use pretty much any USB-C charging cord. They are commonly used with Android phones.

It is still working same as it was new.

This is a game changer when it comes to those who work in factories as the conditions in said work places have steadily declined due the overly disregard for human safety in favor of the ever increasing desire for greed. When working in temperatures in excess of 100 degrees fahrenheit, with no reprieve, unfortunately this may be the only answer for those seeking relief. Amusing, possibly, but this device could literally save lives, as hyperbolic as that may sound to those who've never experienced that reality..
