Not good for USB fan

One is working, one is broken, and one is flashing at high speed and the fan is slowing down. Keep looking for the one with the best track record.

Pros

Instructions for use: Plug the controller into a phone charger or wall charger, insert the fan's USB plug into the controller's USB port, and then rotate the adjustment knob to adjust the low and high air volume . Turn the knob clockwise to increase the air volume. Turning it counter-clockwise will soften the air supply and the knob has a switching function.

Cons
