Review on Mikikin Portable Mini Clip-on Stroller Fan: Versatile, Quiet, USB Rechargeable, Ideal for Home, Office, Car, Travel, Camping, Outdoor by Joe Patterson

I play the violin both solo and in a chamber ensemble. We play a lot of gigs, mostly weddings and parties and I'm usually sweaty after bringing all the gear and setting it up. I attach this little fan to my music stand and it's just great. I leave it on high speed for the first 30 minutes or so to cool down, then switch to medium speed for a while. Thus, it lasts about 3 hours, which is suitable for most concerts. When I need more time, I just plug it into a portable charger with a small power bank (which includes 2 x 18650 batteries, $10 on Amazon) and it can last most of the day. It's so small and quiet that I can't even hear it when there's noise around. It's easy to set up, but I wish the neck was a little stiffer. This is exactly what I was looking for to feel comfortable, I wish they had them many years ago.
