Review on 🔌 ELUTENG 120mm USB Powered Fan with 3-Speeds, 1500PRM, Portable Cooling for Gaming PC, Tablet, TV Receiver, Router, DVR, PlayStation, Xbox, Computer and More by Kelly Sadiq

I have a costume mask with lenses I see through that periodically fog up from breathing. I installed one of them in the mask, facing the lenses, and ran a cable through my suit to a phone charger sewn into my shirt. It worked PERFECTLY. A full day of clear vision at low speed and a light breeze at high speed. Very quiet. Even at high speed, the noise wasn't that noticeable and literally touched my head.
