Adopting a double fan head independents operate structure, it can achieve wide angles three-dimensional airs supply, cover a larger space inside the car, and quickly reduce the cabin temperature. There are three voltages specifications to choose from: 5V/12V/24V, which perfectly fit the power supply systems of different car models. Equipped with automatic shaking function to achieve left and right wide angles sweeping, while supporting manual gear , the airs supply angles and wind speeds gear can be freely switched according to needs, flexibly responding to the cooling needs of different driving scenarios. Specially designed for long distance transportation, low-power and high efficiency motors are paired with optimized circuits to ensures long lasting and stable operate. Adopting mechanical button control, the interfaces is simple and intuitively, and can be quickly adjusted without distraction during driving.
