Quick Start: How to Use Your USB Rechargeable Car Aroma Diffuser
1. Charge the Diffuser
Before first use, fully charge the diffuser using the included USB cable. A full charge typically takes 1.5–2 hours and provides multiple hours of run time depending on the mist setting.
2. Add Fragrance
Use only Saintdeland car fragrance cartridges or the recommended essential oil blends. Open the reservoir following the manual, insert the cartridge or add the specified drops, and secure the cap to avoid leaks.
3. Mount in Your Car
Place the diffuser on a flat surface, in a cup holder, or use the included clip for vents (if provided). Ensure it is stable and does not block airbag or ventilation controls.
4. Operate
Press the power button to select mist intensity and LED modes. For best results, choose a low or medium setting for continuous light scent and a higher setting for quick refresh.
Maintenance: Keep Your Diffuser Working Smoothly
Routine Cleaning
Wipe the exterior with a soft, dry cloth weekly. Empty and rinse the reservoir with warm water every 2–4 weeks. Do not submerge the base or USB port.
Deep Cleaning
For residue, use a cotton swab dipped in isopropyl alcohol to gently clean the atomizer and contact points. Allow all parts to dry completely before reassembly.
Battery Care
Charge regularly and avoid leaving the battery fully depleted for long periods. Store the diffuser partially charged if not used for months.
Safety Tips & Troubleshooting
Only use approved fragrances. If mist output decreases, check charge level, clean the atomizer, and ensure the cartridge is properly seated. Contact Saintdeland support for persistent issues.
Saintdeland combines advanced technology, global scent research, and strict quality control so your car fragrance experience is safe, reliable, and delightful.
