Portable Fan Hand Free Small Personal Mini USB Fan 2000mAh Rechargeable Battery Operated Neck Fan 12H Working Hours 3 Speeds 360 Degree Adjustment Head for Office Travel Outdoor Camping(Black)

This is an update to my previous review.I had thought that I'd have to hold the unit against my face, for example, to feel any coolness, which defeats the purpose and hands free use case while travelling /biking/ hiking.Summer's almost over now, but I received a replacement unit, which seems to work great. It is slightly bigger - the whole piece as well as the fans themselves. It must be an improved model the manual says DNF Y2The good thing I find with this piece is that at a slight marginal extra weight, the air flow seems strong and pronounced and also seems flexible enough such that the air flow is towards me and I can feel the air hands free.Hope it does not stop working suddenly/ mysteriously like the previous unitThank you LUWATT!------------------------------------------------------------------------------You would think that such a fan is a great idea while hiking or biking out in the heat in sunny warm days.This is very light and wearable for that, but otherwise useless, because the air flow will not really help you feel any cooler at all.I desperately hoped it would work, and tried to use it 2-3 times while riding the bike - but it did not work at all. just had extra stuff to carry and worry about, and worse, on the 3rd attempt to feel happy about the purchase, one of the fans would not even move. Have no idea why. Now it is a purely cosmetic junk waiting to be thrown.With one fan running, i can may be hold it against my face while I am sitting on a chair at home or office - but you do not need a USB fan for that. A regular fan or AC would serve indoors.I wonder how anyone can use it.

Too many people forget that they can always put clothes on and the rest of who are dying from the heat they insist on blasting simply can’t take all our clothes off in public.Thus was my difficulty last month when we travelled for business trip Vegas.I had a heat stroke in 1995. My core got up to 104. My body does not regulate temperature properly because of it.Yet despite it being in the upper 70s outside with little relief from the hope of any air conditioning (or smoke free air), this little beaut made it bearable.Had to charge frequently, because I kept it on high, but this is a gem. One I will not be traveling without ever again.And for those of you who are always “cold”, how about you carry a sweater with you? Because you may be the unfortunate souls I decide to strip off my layers in front of. And wat a sandwich once in a awhile.I’m dying of heat, fanning myself, panting, drinking tons of water, and begging the airline attendant to plead with the pilot to turn the heat down a few degrees... and begging for ice in a baggie to bring my temperature down.You could AT LEAST SHUT THE WINDOW BLINDS, COVER UP, AND WEAR MORE LAYERS (including long pants) so the rest of the world can survive!Until then, my impending public nudity, me fanning like crazy (including my wildly flapping bat wing arm fat possibly accidentally hitting you), me fanning toward you (bringing on my giddy shadenfreuden), or other mishap will likely impact you and your vision.This thing is AWESOME! You are not.

I purchased this product and it came with the sports fan and a USB-C to USB-A Charging cable. Out of the box, the fan worked as expected. The fan power is too trivial unless you set it on the highest setting, which is surprisingly noisy. (Maybe use a brushless motor/fan?)Upon charging it, I used this product until the battery died, then placed it on the charging cable provided. The RED LED did not come on and after checking it 30 minutes, 1 hour and 2 hours later, the battery was not charged or charging and the fans were inoperable.All in all, there may be some better fans out there, as when it did work, I only noticed a difference if I was in an already air-conditioned space. Using these out in the blazing sun makes no difference and the noisiness of the fan compared to its ability is quite inferior.I am afraid that, at this time, I simply cannot recommend this product for its intended use.

I will keep this because I expect it to be useful but it does have a couple of issues. When on, the buzzing of the motor is annoying, not loud, but you feel the sound and motor vibration where the device rests on your collarbone. The fans are roughly 2-in in diameter, twice what I expected. The lowest speed is adequate, the second speed should handle most reasonable temperature situations, and the highest speed really pushes a lot of air through. Feels like having a small plane on your shoulders but smoothes out the vibrations a bit, too. No cooling, just a fan, and a fan can only move air. The charging cable doesn't fit well. Not sure the cable works. The red light came on but never went blue, even after 4 hrs of charging. If I find I can't recharge it, I'll try a different cable. If it still doesn't charge, I'll return it.

I used this fan while putting my makeup on in my apartment because the bathroom gets hot. Initially it worked just as intended and brought much needed relief during the hot summer mornings. I also used it while I would watch television on my couch, and again much needed relief. However, the left side of the fan stopped working all of a sudden, just totally went out on me. I put it away intending to send it back. I tried it one more time and the fan began working again. Not sure if this is just a short that happens from time to time but it was very disappointing. Also after some time on one side of my face a felt a little windburned.
