Review on Hands-Free Neckband Fan Computer Accessories & Peripherals by John Shorter

Charged and used once when mowing the lawn. It only lasted an hour or an hour and a half before the battery died. Brought it home to charge the battery and in less than a couple of minutes it showed it was fully charged. Try turning it on, but it won't turn on. After troubleshooting I found that the battery was dead. The fan will only turn on when connected to an external power source via the charging port.
