Review on 💨 5000mAh Battery Operated Neckband Fan - Long 22H Working Time, Strong Airflow, Natural Wind Mode, 360° Adjustable Personal Fan for Outdoor Travel, Office, and More (Blue) by Marvin Leon

Bought for my husband when high temps hit us in Arizona. When working with documents, the weight is not too heavy. But if he has to go under a car/helicopter you can't reach him, stay where you are he says. In addition, hot air was constantly being blown into him when he was working outdoors. Didn't know that would happen. That's why he gave him bad grades. But he likes the long battery life. When not hot, it can be used, but not in extremely hot conditions. I think it depends on how you want to use it.
