Treva Mini Clip On Fan - Tiny Personal Fan Clips Onto Cell Phones, Tablets, Laptop Computers – Cordless, Battery Operated - Portable Cooling For Travel, Bed, Camping, Beach, Outdoors, Gray

I use it to cool down my Bass Amplifier… works really well.

Do not buy these. Are they a tiny squirrel cage fan? Yes. Do they blow out enough air to notice that they are on and trying to cool you down? No. These are not worth your time. Do not buy these.

Very weak fan and it churns thru batteries like no one’s business. It would have been more cost efficient to just get one that plugs into a power source.

On a hot day, I guess any breeze is welcomed. Unfortunately it isn't strong enough when a couple of feet away. As a stroller fan, the baby just kept removing it from the side of the stroller and held it in from of him instead. as a small table fan it wasn't much help in front of the computer but it did help keep the laptop cool when I aimed the fan towards its vents. Battery life is good. I used rechargeable batteries. Sturdy enough to survive a rough handling 3 y.o. toddler.

We had a long car ride across country and I needed a small fan to clip on my rabbit cages to keep them cool on our trip. These worked perfect clips on easy and stayed on the whole time without having to adjust it was the perfect amount of air for my rabbits. As for using it for me when I was hot and needed to use it I felt like it didn't blow enough cold air or hard enough to feel it.
