Review on Oct17 Portable Stroller Rechargeable Operated Heating, Cooling & Air Quality by Cassie Marie

Wow, that's really cool stuff. I noticed that it runs on an 18650 battery, which I have a few that I use for flashlights and vaping. My wife bought this for her stroller when we vacation in Tennessee this year. Now I know I'll have plenty of spare batteries, and the charging port is handy too. This fan also has speed control, which is also a big plus. The speed control is on the potentiometer, not the clicking speed control. I like this option better because you can smoothly control the speed of the motor. Very good.
