Review on 🌀 Portable Neck Fan, Hands Free Design with Strong Airflow - 3 Levels, 360° Rotation, USB Rechargeable Mini Personal Fan for Sports, Office, and Outdoor Use (Black) by Pete Door

A neat little gadget and a bargain. The promised 3-5 hours are enough if it doesn't blow at maximum power. Admittedly, this is hardly an issue as I rarely need to go past the second stage and it's powerful enough to reach my face from about a foot away. The flexible neck is a plus, but at higher settings the fan glides very softly so the fan head needs correction, but that's another indication of blowing power. It also comes with a small charger, which is nice because the batteries get boring. The specified load time is pretty accurate. Overall, it's definitely worth a look and more than worth the price.
