Aroma Diffuser Humidifier

Ultrasonic waves: High-frequency vibrations turn water into a very fine cool mist. Compact and portable: The small water tank takes up little desk space and fits easily into car cup holders. LED light / night light: Usually features decorative LED lighting, either colour-changing or steady. USB power: Can be run conveniently from a power bank, computer or car charger. Aromatherapy support: Add a few drops of water-soluble essential oil to the tank to scent the room.
