coldSky Handheld Fan

With its 4000mAh battery, the fan is designed to last through a full day of intermittent use. Exact runtime depends on which of the five speed settings you choose, but you can expect several hours of continuous cooling on lower settings.

Yes, the lower speed settings are engineered to be very quiet, making them suitable for shared workspaces or quiet environments. The higher settings will produce more audible airflow, which is expected for increased power.

The integrated LED display clearly shows your current battery percentage. This allows you to monitor your power levels in real-time so you can recharge before the battery runs completely dry.

The fan is designed with portability in mind and features a compact form factor that fits easily into most standard handbags, backpacks, or even large jacket pockets. It is lightweight enough to carry comfortably throughout the day.

While the device does not have a physical lock switch, the power button is recessed to minimize the risk of accidental activation. However, we recommend placing it in a separate pocket or pouch to ensure it doesn't turn on while packed away.
