28V Cooling Fan, Two Battery Set, with Battery Level Indicator. - Brand: elemal - Number of Cooling Fans: 2 - Voltage: 28V - Charger: Included - Cables: Included - Color: Black Two batteries are included. I used it for a total of 10 days, but I no longer need it, so I am selling it. The fans are black, unlike the ones in the picture. The battery life is good, and the airflow is excellent, I think. Thank you for looking.
