How long will one charge last and how can I power the fan?

The built-in 4000mAh battery delivers anywhere from 5 to 23 hours of runtime depending on the selected speed, and you can also run the fan continuously via USB when near a power source. This dual power design gives flexibility for long trips or stationary use.

• Low speed: longest runtime (up to 23 hours).
• High speed: stronger airflow for short bursts (runtime reduces accordingly).
• USB-C input for continuous use and easy charging.
• Emergency power bank function to charge phones from the fan’s battery.

Is this fan truly quiet enough for sleeping or working?

Yes — the fan is engineered for low acoustic output with a maximum noise level under 35 dB, so it won’t interfere with sleep, calls, or focused tasks. Its compact motor and blade design prioritize smooth airflow while keeping sound minimal.

• Max noise below 35 dB for undisturbed sleep or meetings.
• Small motor tuned for minimal vibration and hum.
• Four speeds let you balance airflow and noise.
• Stable base and foldable bracket reduce rattling on surfaces.

• Compact dimensions and light weight for easy carrying.
• Foldable bracket protects the fan while travelling.
• Detachable grille and blades for quick cleaning.
• Sturdy construction designed for everyday handling.
