This stroller fan by Anglink is powered by a 2600 mAh battery. That battery is rechargeable. The unit comes with a USB charging cable. You can power it for a long time just pulling power via a USB port.

The fan itself has 4 speed settings. This fan will run up to 8 hours on the slowest speed and three and a half hours on the fastest speed.
This unit has a wider than average clip for holding it in place. It can stand alone using that clip as a base, and that makes it more stable than the average stroller fan if it isn’t mounted on the stroller.
The clip is strong on its own, but you don’t need a lot of force to remove it and re-mount the fan.
Like other stroller fans on our list, it can rotate 360 degrees both vertically and horizontally. Turn it all the way around. Rotate it forward, backward and around. Direct the air flow wherever you need it.
What is the Downside?
One downside of the model is the mediocre quality. Get a good battery, and the unit may still stop working after you’ve owned it just a few months. While the fan keeps curious fingers out, the battery compartment door may fall off.
And the fan can shift as you push the stroller around. Hit a bump, and now it isn’t pointing at the baby’s face.

A 3M vortex tube. It can actually produce freezing temperatures.

Squirrel cage fans are great for moving large volumes of air.

When we trashed our old gas furnace I saved the squirrel cage blower fan and I use it to circulate air in my shop/shed.

And when we had a water leak in the basement I used it to dry the floors. I opened a window at one end and exhausted the air through a window at the opposite end. Worked great except that it was Summer and the screen at the entrance end kept getting blocked by mosquitoes and other bugs.
