Dual-head car dashboard fan with a built-in motor and two-speed design provides strong airflow to cool quickly, helps dissipate heat, and reduces tobacco smoke or dust. It also eliminates pet odors and improves air circulation to keep the cabin air fresh. 360° horizontal rotation and 180° vertical tilt let you position the fan precisely on the dashboard for both driver and passengers. Power options include USB 5V or 12V/24V ports, so it can be powered by a power bank, a car, or a truck. Compact size and footprint: approximately 21.14 x 14.5 x 17.5 cm (8.26 x 5.71 x 6.88 in). The dual-head unit fits on the dashboard without blocking your view and is easy to carry. Use scenarios: - In a smoker’s car, to quickly cool and refresh the cabin while reducing smoke exposure. - On road trips or taxi/rideshare use, to circulate air, remove odors, and keep a comfortable environment for all occupants. - In vehicles with pets or dusty environments, to improve air quality and comfort during travel.
