How long does the battery last?
Up to 9 hours at low settings; varies by speed. The LED display shows real-time battery percentage so you can plan your charge.
How quiet is it? Is it 30dB?
At the lowest setting, the fan operates at approximately 30dB — quieter than a whisper. Higher speeds produce more sound, which is normal for any fan. The 7-blade design helps keep airflow smooth.
Can it be wall-mounted?
Yes. A mounting hook is included. Use flat on desk or hang securely on a solid wall.
Can I use it while charging?
Yes, pass-through charging supported. Standard 5V/2A USB-C charger recommended. 1M cable included.
How do I control 100 speed levels?
Touch: long-press 2s on/off; tap +/- for 20-level jumps; long-press for stepless fine-tuning. Display shows exact level.
