USB mini humidifier for home and car with 300ml water tank capacity and six-hour runtime in white, pink, or green ABS construction for desktop air moisture
USB Mini Humidifier with 300ml Water Tank for Home and Car Use

This compact humidifier is designed to add moisture to the air in small, personal spaces such as a desk, bedside table, or car interior. Powered by a standard 5V USB connection, it draws minimal energy at just 2W while its 300ml water tank supports around six hours of continuous operation. The fine mist output, adjustable between 30-50ml per hour, can help alleviate the discomfort of dry air in targeted areas. Its small footprint, measuring 75mm square and 116mm tall, makes it easy to place without occupying significant space.
Features and Construction

The humidifier's design prioritises portability and simple operation for everyday environments. It requires no specialised installation, simply needing a USB power source and periodic refilling of its integrated water reservoir.
Material and Build
The main housing is constructed from ABS plastic, a material chosen for its durability and light weight. Additional components use PP plastic, contributing to the unit's overall structure. These materials form a solid, splash-resistant enclosure for the internal electronic components that generate the ultrasonic mist.
Size and Practical Fit
With dimensions of 75mm in width and depth and 116mm in height, the humidifier is suited for placement on narrow surfaces. Its square profile provides stability, and the light construction means it can be easily moved between locations, such as from a home office desk to a car's centre console.
Uses and Placement

The primary application is to increase humidity levels in localised, dry environments. Its USB power flexibility allows it to function wherever a 5V port is available, broadening its usefulness beyond a fixed plug socket.
Event or Professional Use
In a professional setting, such as a personal office or reception desk, the humidifier can run quietly throughout the workday. The six-hour runtime covers a typical shift, and the low 2W power consumption ensures it does not significantly impact energy costs. The mist output is subtle, avoiding distraction in focused work environments.
Everyday Home Use
At home, the unit is well-suited for bedrooms, studies, or nurseries where dry air from heating or air conditioning can cause irritation. The 300ml capacity means it can run overnight or during an evening's use without needing a refill. Available in white, pink, or green, it can blend with various room decors.
Benefits and Buying Value

This product offers a straightforward solution for managing air moisture in compact areas without complex setup or high running costs.
Reuse and Low Maintenance
The humidifier is designed for repeated daily use with minimal upkeep. The water tank is easy to access for cleaning and refilling. Using only water and electricity, it has no consumable filters or cartridges to replace, keeping ongoing maintenance simple and cost-effective.
Why Choose This Product
