The RV Simple Fan is a portable ventilation device designed for camping and road trips, featuring a lightweight foldable structure, dual power supply (USB/battery), three-speed wind settings, a low-noise motor, splash-proof design, removable washable filter, 360° rotating bracket, and energy-efficient operation. When folded, it is only the size of an A4 sheet, making it easy to store in an RV compartment. The dual power system ensures continuous operation even in outdoor environments without power outlets, ideal for long-distance travel. The splash-resistant body and detachable filter adapt well to dusty or humid camping conditions, while the quiet operation and multi-angle airflow enhance comfort during nighttime rest. Constructed with flame-retardant ABS material, it combines safety and durability, making it the perfect choice for improving air circulation in RVs.
