🔧 Quick Troubleshooting Tip
If the unit powers on and immediately shuts off, this may be caused by water being poured in too quickly, or — in rare cases with long-term essential oil use — a thin water film forming over the atomizer plate. Simply break the film gently with a cotton swab (or another soft, non-sharp object) through the circular port at the base of the water tank to restore normal operation.

Frequently Asked Questions
Q: What size room is this 500ml essential oil diffuser and humidifier suitable for?
A: This 500ml cool mist diffuser works well in small to medium-sized rooms — typically up to approximately 200–300 sq ft — making it ideal for bedrooms, home offices, nurseries, and living room corners. For larger open spaces, consider running multiple units.
Q: Can I use essential oils in this humidifier diffuser?
A: Yes! Simply add a few drops of your favorite essential oil directly into the water tank along with clean water. The ultrasonic mist will carry the aroma throughout the room. Always use pure, high-quality essential oils for best results and to protect the atomizer.
Q: What kind of USB charger do I need for this diffuser?
A: You need a USB charger with an output of at least 5V/2A. The included USB cable connects to any compatible USB adapter (not included). A 5V/1A adapter is not powerful enough and the unit will not operate correctly with it.
Q: Does the LED light stay on while the diffuser is running?
A: You can choose to have the 7-color LED cycle through all colors, stay on a single color of your choice, or turn the light off entirely — giving you full control over the ambiance while the mist continues to run.
Q: Is this diffuser safe to run overnight?
A: Yes. The device features an automatic shut-off function that turns the unit off when the water level drops too low, making it safe to use while you sleep. Its near-silent 36–45 dB operation also ensures it won't disturb your rest.
