i work 10 hour days. the only setting that lasts that long is 2/4. and it is underpowered no matter the setting you have it on. it's much smaller than expected. i guess blame me for not looking at product dimensions, but it is overall really disappointing. the clips are not strong, and so your shirt pulls out of it every time you move even a little bit. i often checked to see if it was on because i couldn't really tell.there is a 2 fan one from another brand on the marketplace. i don't think i am allowed to link it in this review, but i just got it in today, and it is a night and day difference. it has 10 speeds, 20,000mah battery, and at 5/10 speed absolutely blows this one on max out of the water. it has super strong clips. if you're looking for something to really help cool ya down while doing outdoor work, spring for the more expensive one that i'm referencing. it even has usb out to charge a device from and a kickstand to turn it into a tabletop fan. very happy with that purchase. very disappointed in this product.
1. not good for inside your shirt. it suffocates very easily due to lack of airflow at the base. a ported housing could solve this.2. very loud, has a high pitched whining noise3. not powerful at all. cheaper brands ive seen have much more airflow4. very big and bulky5. cheaper options available pros:1. battery life is good, 4-5hrs at high speed
the fan does not blow a whole lot of air at all. and the battery only last about 5 hours far from the specs that i seen when i were selling. it said it would last 24 hours. but nothing close to that in the way it looked on there like it was blowing out a lot of air it does not. i would not buy this if i were you. i would go with a different brand
we bought these for use when working on our food truck which gets extremely hot. i like that it had clips which allowed us to attach the fan to our shirts while still being able to serve customers. however, i guess we chose the wrong wattage because the force of air was not strong enough to keep us cool. it did the job when we opened the freezer and the cool air was sucked through the fan and blown on us. the moments we could do this were far and in between though.
recently bought this to combat the high temps. however, as a big man, i wasted my money. no matter where i clip it, i barely feel it unless i suck my gut in and have my shirt a certain way. only reason i gave it a 3 is because i gave it to my kid and he loves it.
