Review on 🌀 Portable Neck Fan, Hands-Free Personal Rechargeable Fan - USB Mini Wearable Sports Battery Powered Face Fans, Suitable For Office, Outdoor, Travel (Black/Red) by Vivian Eker

Update: A minute ago I wrote TLDR which for some reason has not survived. The item's red LED charge indicator didn't go out for a single day, even after I unplugged it and completely drained the battery. I've tried leaving it on and only unplugging it when needed, but the constant draining probably killed the battery from freezing. Disappointed, he didn't last more than a few months. It's as light as can be while still supporting reasonably powerful fans and a decent battery. Definitely makes a big difference for me when I'm in the studio and generally because of my nervous issues (I'm always hot). Battery life is good considering it's driving two separate fans, although you'll find smaller individual fans that last much longer (so be prepared).
