Review on 🌬️ Ultimate 10000mAh Portable Neck Fan: Wearable, Rechargeable, 48H Working Time – Ideal for Travel, Hiking & Outdoors by Jon Dunn

My God, that thing is heavy! I have several less expensive, highly rated Revain neck fans, and while this one has longer battery life, it's not worth the extra weight. The weight of the battery causes it to move from side to side with EVERY movement. Stick with smaller fans, the battery lasts for everything you do. No need for marathon battery life at the expense of convenience. However, it does what it says, which is why it gets at least three stars out of five.
