Small USB Desktop Humidifier with 320ml Capacity and 4-Hour Timer

This small USB desktop humidifier is designed for personal spaces where a compact, low-power moisture solution is needed. With a 320ml cup capacity and a rated power of only 3W±0.5W, it provides up to 4 hours of operation via its built-in timer. The ultrasonic nebulizer works at a vibration frequency of 108±5HKZ and covers an area of about 8m², making it suitable for desks, bedside tables, or small office cubicles. It is powered through a USB connection at 5V, so it can run from a laptop, power bank, or USB wall adapter. The unit measures 120 x 97 x 97mm and weighs 260g, and it is available in plain white, pink red, or classical green. The body is made from ABS material and PC, which are common plastics used in small appliances. Package contents include the humidifier, a manual, a cotton swab, and a data cable.

Features and Construction

The humidifier combines a compact form factor with a straightforward set of features. Its 320ml cup capacity and 4-hour timer define its operating cycle, while the USB power supply adds flexibility. The materials and dimensions are clearly stated, helping you judge whether it fits your space.

Material and Build

The main body is made from ABS material and PC. ABS provides a rigid, impact-resistant shell that is common in small household devices, while PC is likely used for parts that need transparency or extra heat resistance. Together, they form a lightweight structure weighing 260g. No additional durability or premium claims are made beyond these stated materials.

Size and Practical Fit

With dimensions of 120 x 97 x 97mm, the humidifier occupies a small footprint, similar to a large mug. The 320ml cup capacity means you can fill it with water for a single session, and the 4-hour timer automatically stops operation. The 260g weight makes it easy to move between rooms if needed. It is designed to fit on a desk or bedside table without taking up much space.

Uses and Placement

This humidifier is intended for small-area use, with a stated humidification area of about 8m². That makes it suitable for personal spaces rather than whole rooms. It can be used in homes, offices, or similar environments where a USB power source is available.

Event or Professional Use

In a professional setting, the humidifier can sit on a desk and run from a computer's USB port. Its 4-hour timer means it will switch off automatically, which can be useful during a workday. The plain white, pink red, or classical green colour options allow you to choose a finish that blends with your workspace. No claims are made about improving air quality beyond the stated humidification area.

Everyday Home Use

At home, the humidifier can be placed on a bedside table or a small shelf. The 320ml capacity provides up to 4 hours of moisture, which may be enough for a night's sleep or a few hours in the evening. The USB power supply means you can plug it into a phone charger or power bank. Keep in mind that it covers about 8m², so it is best for personal spaces rather than large rooms.

Benefits and Buying Value

The main benefits come from its compact size, low power consumption, and simple operation. It does not require a mains socket, and the timer adds convenience. The materials and construction are standard for this type of device.

Reuse and Low Maintenance

The humidifier can be refilled and reused. The included cotton swab can be used to clean the nebulizer area, and the cup can be rinsed. No specific maintenance schedule is provided, but regular cleaning of the ultrasonic nebulizer is generally recommended to keep it working. The USB data cable is reusable with a compatible power source.
