The DAYBETTER USB Ultrasonic Humidifier is a 190 mL cup-shaped personal humidifier that runs off USB power. It puts out fine cool mist at low noise, with continuous or intermittent mist modes, a color-changing night light that can be switched off, and auto shut-off when the tank runs dry. It also accepts water-soluble essential oils. It suits a desk, nightstand, car cup holder or travel bag rather than a full room; its small tank means frequent refills, and its 3.7-star average from 18 ratings suggests mixed satisfaction. Against larger ultrasonic humidifiers it trades capacity and room coverage for portability and a light.

With 18 ratings averaging 3.7 out of 5, feedback is mixed. Owners like the small footprint and the light, but the tiny tank and modest mist output draw complaints.
This is a compact USB ultrasonic humidifier with a 190 mL water capacity. It produces a fine, cool nano mist at a low noise level. Its cup-shaped body fits in most cup holders, so it can be used in a car, on a desk, on a nightstand, in an office or in a travel bag.
It has two mist modes: continuous mist for steady moisture and intermittent mist for longer use. A built-in color-changing night light offers Soft Gradient Light and Dynamic Flowing Light modes. The light can be turned off for mist-only use.
The humidifier is made of ABS, PP and silicone. It works with water-soluble essential or fragrance oils. It shuts off automatically when the water runs out.
