Review on 🌀 USB Rechargeable Neckband Fan - Hands-Free Personal Fan with Headphone Design | Portable Wearable Mini Fan (Blue, 3 Speeds, 5-10 Working Hours) by Jacob Seymour

Apparently similar fans are sold by dozens of resellers. My only concern is that the fan might come with a crappy battery and not last long. I bought my fan from Maimuxi and am happy to report that: - The fan has a battery cover that allows you to replace the 18650 lithium battery, although you will need a screwdriver to attach the cover. The supplied battery was tested by my charger to 1620 mAh capacity. Not 1800mAh as advertised, but not far off. I replaced the standard battery with a 3200mah battery and kept the standard battery as a backup. Should get pretty good mileage from this fan. For the price, it's hard to beat.
