Review: I'm going to use this a lot - Unfortunately my work takes me into the outdoors and other hot environments in heavy clothing that doesn't breathe at all. And this is in Florida. I hoped this would provide some relief and it certainly does. The best way I can describe it is I am still not totally comfortable, but if this thing is turned off for an instant I want it back on right away. Details: Weighs about the same as a smart phone. About the thickness of a hard pack of cigarettes. Its about 3 inches wide and a little less than 5 inches long. It fits in the typical breast pocket of a man's shirt. It makes a noise that sounds like a hair dryer, but very, very quiet. Its certainly not noisy. I can't hear it unless I am in a quiet room and even then its not objectionable. Because rechargeable batteries have a slightly lower voltage than disposable ones, it runs slightly slower with rechargeables, but its a small difference. I tried it with new alkalines and some fully charged NIMH's and compared its speeds. I measured that it draws 200mA from two fresh charged NiMH batteries, so a little more than a ten hour run time on a set of batteries, although you will probably want to change them before its fully dead as it slows down. The fan has one speed. Its no powerhouse as you can imagine but it feels good. Its enough to make a little wind buffeting noise around my ears. Its actually more air than I expected something like this to produce. There is a slider switch on the side to turn it on and off. To me, the lanyard is the only place where the price really shows. Its a thin string that is slightly uncomfortable against my neck. It has no provision for adjusting it to get the fan closer to your neck, but you can accomplish this by tying the string at the top and letting the extra hang down the back of your neck. If the fan outlives the lanyard I will replace it with something more comfortable and adjustable. I think it might be possible for girls with long hair to get some caught in the fan if it hangs down over their chest. Overall fantastic product.

### ⭐⭐⭐⭐ works well
*by A***R on July 15, 2026*

works well I use as a back up for ones I have that are charged with usb, if going to the park or outdoor event, I like to have a backup incase I wear down my charged one - this isn't as powerful but moves air to help keep me cool when hot out
