Q1: How does the intelligent sensing system solve the "over-scenting" problem common in car air fresheners?
A: The ST-01SC uses an integrated lithium-powered sensor that detects the vehicle's vibration. By automatically starting and stopping with the car, it prevents fragrance from accumulating in a parked vehicle, ensuring a fresh, subtle aroma exactly when you need it while significantly extending oil life.
Q2: Does the water-free atomization pose any risk to high-end leather or electronics within a luxury cabin?
A: No. Unlike traditional humidifying diffusers that release heavy moisture, our advanced water-free atomization converts pure essential oil into a dry nano-mist. This stays suspended in the air longer and leaves zero residue on surfaces, protecting your interior's premium materials.
Q3: Can the arc ambient light be synchronized with the vehicle's existing interior lighting?
A: While the light is controlled via the unit's interface, we have provided three switchable color temperatures—White, Yellow, and Blue. This selection was specifically chosen to harmonize with the most common dashboard and ambient lighting schemes found in modern professional and luxury vehicles.
Q4: Is a 56-hour battery life sufficient for professional drivers or long-distance travel?
A: Absolutely. Because the ST-01SC portable car diffuser only consumes power when the car is in motion (thanks to the start-stop sensing), 56 hours of continuous use typically translates to several weeks of standard commuting. This makes it a "low-maintenance" asset that only requires a quick Type-C recharge once or twice a month.
