A small ultrasonic humidifier and essential oil diffuser powered by USB. It produces a cool mist and has a columnar design that fits on a desk or nightstand. It lacks a timer and automatic shutoff, so you must unplug it when the water runs low. Compared with other USB humidifiers, it offers dual functionality but fewer safety features.

This is a USB-powered ultrasonic humidifier and diffuser for home or office use. It uses ultrasonic mist to add moisture to dry air and can also diffuse essential oils.
The unit has a columnar design and a large water tank for extended use. It runs on USB power, so it can sit on a desk, bedside table, or in a living area.
It has mechanical controls and no timer. It does not have automatic water shortage protection or power failure protection, so the water level needs to be watched and the tank refilled promptly to avoid dry running.
