Charging is handled via a convenient USB-C port, while the intelligent Li-ion charging circuit helps provide safe and efficient charging. A full charge takes approximately 3 hours when using a 5V/2A power adapter.

Its foldable construction makes it easier to transport and store, while the integrated lockout switch helps prevent accidental activation during transportation. The removable rear cover allows easy access for cleaning, helping maintain the fan and its airflow performance over time.
