1. Dual Nozzles for Efficient Diffusion Adopting a dual-sided mist outlet design, the device simultaneously releases fragrance molecules, expanding coverage and rapidly purifying the air inside the vehicle, eliminating odors and ensuring the fragrance evenly fills the entire cabin. 2. Intelligent Start/Stop Sensor Built-in vehicle start/stop detection module automatically activates the device when it's powered on and delays shutting off after the vehicle is powered off (e.g., 30 seconds to remove residual fragrance), preventing wasted power. This eliminates manual operation and saves energy. 3. Multiple Mode Switching Supports intermittent spray (e.g., 15-minute spray) or continuous spray mode, adjustable via the button, to meet varying needs for short commutes or long drives, while preventing overpowering the fragrance. 4. USB-C Fast Charging + Large Capacity Equipped with a 500mAh lithium battery, the device can be charged in 2 hours via the Type-C port for 24 hours of battery life. Compatible with car chargers or power banks, it features automatic power-off protection for water shortages, ensuring safety and durability. 5. Magnetic Structure + Dual Use for Essential Oils and Chips The device is magnetically fixed to the air vent or center console, allowing for interchangeable essential oil bottles or solid-state aromatherapy chips to suit your liquid or solid fragrance preferences. Removal is easy and leaves no traces.
