Great device, recently bought the battery pack and dock with it and hugely satisfied with the quality and service of the products and this company!
Robert Golz –
Very satisfied at first. However the Duux now beeps when on the charger. Removed the battery and then the beep is gone.
So charger / battery is acting up .

Expensive battery because it lasts very short and also drains very quickly when not in use.

Hello,
Thank you for writing a review! Sorry to hear that you are not satisfied with the battery life. When the fan is not being used it does indeed slowly drain, this is because the fan is then in standby. You can prevent this by removing the battery from the ventilator or putting it on the charger.

Great machine, quiet and lots of airflow. Light weight, easy to move because of the placed battery. No tangling with wires. A topper.
