Portable USB rechargeable fan

The Ruth's sister portable air cooler is a compact rechargeable fan designed for personal desk use. It operates from an internal battery that is charged through a USB connection. Three speed settings let the user adjust airflow to suit the immediate environment. An integrated LED light adds a secondary illumination function.

Thermals noise and power draw

The device runs directly from its built-in battery during use so it draws no power from the host system. Fan noise varies with the selected speed setting but remains at a low personal-cooling level. Heat output is minimal because the low-voltage motor and LED produce very little waste heat.
