1. Product Overview
This device is a USB-powered mini ultrasonic mist humidifier and oil diffuser designed for use in vehicles and other small spaces. It utilizes ultrasonic technology to produce a fine mist, which can disperse fragrance from essential oils and add humidity to the air. The compact design allows it to fit conveniently in a car cup holder.

The diffuser is suitable for various environments, including cars, bedrooms, offices, and homes, providing a versatile solution for air humidification and aroma diffusion.

2. Safety Information
- Avoid direct skin contact with undiluted essential oils.
- Keep the device out of reach of children and pets.
- Ensure proper ventilation in the area where the diffuser is used.
3. Setup Instructions
3.1 Unpacking
Carefully remove all components from the packaging. Ensure the USB cable is present, as it is typically located inside the device.
3.2 Power Requirements
The diffuser requires a power adapter or USB charger that provides at least 5V 1A. Using a power source with less than 1A may result in the device lighting up but not producing mist.

3.3 Filling the Water Tank
- Open the upper cover of the diffuser.
- Fill the tank with water. If desired, add a few drops of essential oil.
- Important: Do not exceed the maximum water line indicated inside the tank. Overfilling can prevent mist production.
- Close the upper cover securely.

3.4 Connecting Power
Connect the provided USB cable to the diffuser and then to a compatible USB power source (e.g., car USB port, USB adapter, power bank).
4. Operating Instructions
4.1 Power On/Off and Mist Modes
The diffuser features a single button for controlling power and mist modes:
- First press: Activates continuous mist mode.
- Second press: Switches to intermittent mist mode.
- Third press: Turns the device off.

4.2 Mist Duration
- Intermittent Mist Mode: Provides approximately 3-4 hours of operation.
- Continuous Mist Mode: Provides approximately 6-8 hours of operation.

5. Maintenance
5.1 Regular Cleaning
To ensure optimal performance and longevity, clean the diffuser every 2-3 days, especially if used for extended periods. Follow these steps:
- Unplug the device and empty any remaining water.
- Add a small amount of warm water and diluted vinegar to the water tank.
- Let the mixture sit for 10-15 minutes.
- Use a cotton swab to gently clean the white circular area in the middle of the water tank.
- Wipe the entire tank with a soft, dry cloth.

6. Troubleshooting
6.1 No Mist or Low Mist Production
- Check Power Adapter: Ensure your USB power adapter provides at least 5V 1A. A lower amperage may cause the device to light up but not produce mist.
- Water Level: Verify that the water level is below the maximum fill line. Exceeding the maximum line can impede mist production.
- Cleaning: If the product has been used for a few days and stops misting, it likely requires cleaning. Follow the regular cleaning instructions in Section 5.1.
- Button Press: Ensure you have pressed the button once for continuous mist or twice for intermittent mist. A long press may only control the light.
