Frequently Asked Questions
Q: Can I use any essential oil in this USB aroma diffuser?
A: Yes! This mini aroma diffuser is compatible with most water-soluble essential oils. Simply add a few drops to the 120ml water tank before switching on the mist function. We recommend starting with 3–5 drops and adjusting to your preferred scent intensity.
Q: How long does the diffuser run on a full tank?
A: With a 120ml water tank and a spray output of 10–15ml per hour, you can expect approximately 8–12 hours of continuous misting on a full tank, depending on your settings and environment.
Q: Is this diffuser safe to leave on overnight?
A: Absolutely. The ESMARTER QT023 features a built-in water-shortage protection chip that automatically shuts the device off when the water level is depleted, making it safe to use overnight. Its ultra-quiet ≤30dB operation also ensures it won't disturb your sleep.
Q: Does the night light function work independently from the mist function?
A: Yes! The ambient candlelight atmosphere light and the mist/aromatherapy function are independently controlled. You can use just the light, just the mist, or both at the same time by using short and long presses of the single control button.
