200ml Portable USB Humidifier with 40mL per Hour Moisture Output for Small Spaces

This portable humidifier delivers practical moisture control for personal spaces with its 200ml water tank capacity that provides approximately 5 hours of continuous operation. The 40mL per hour spray volume creates a consistent humidity level in areas up to 15 square metres, while the USB-powered design with DC5V input and 3.5w consumption makes it economical to run from computers, power banks, or car outlets. Available in four colour options including pink, dark blue, sky blue, and white, this compact unit measures just 70x66x213mm and weighs only 140g for easy placement on bedside tables, office desks, or car dashboards.

Technical Specifications and Construction Quality

The humidifier combines precise engineering with durable materials to deliver reliable performance in various environments, from home offices to vehicles during long journeys.

Compact Design and Dimensions

With product dimensions of 70mm width, 66mm depth, and 213mm height, this humidifier occupies minimal surface area while providing substantial moisture output. The packaging measures 72x72x221mm for secure shipping, and the unit's 140g net weight makes it genuinely portable without compromising the 200ml water capacity. The colour options include pink, dark blue, sky blue, and white finishes that maintain their appearance through regular use.

Electrical Performance and Power Requirements

The humidifier operates on DC5V input with a working current range of 200mA to 450mA, drawing just 3.5w of power during operation. This low power consumption translates to approximately 0.028kWh for 8 hours of use, costing less than 1p per day at typical UK electricity rates. The USB connectivity means compatibility with standard 5V power sources including laptop ports, mobile power banks, and car adapters without requiring specialised power supplies.

Construction Materials and Durability

The ABS (acrylonitrile butadiene styrene) and PP (polypropylene) construction provides chemical resistance against water minerals while maintaining structural integrity in humid conditions. These engineering plastics offer impact resistance that withstands accidental drops from desk height, and their lightweight properties contribute to the 140g total weight without sacrificing the 200ml water tank capacity or the unit's overall durability during regular use.

Practical Applications and Usage Scenarios

This humidifier serves multiple purposes across different environments, from improving air quality during sleep to maintaining comfort during extended vehicle journeys.

Bedroom and Sleep Environment Use

For bedroom applications, the 200ml capacity provides sufficient moisture for approximately 5 hours of continuous operation, covering typical sleep durations without requiring refills. The 40mL per hour output maintains humidity levels that can reduce morning throat dryness, while the quiet operation at 200mA-450mA working current won't disrupt sleep. The compact 70x66x213mm dimensions fit on nightstands without occupying valuable surface space needed for lamps or books.

Office and Workspace Applications

In office environments, the humidifier's USB power compatibility means it can run directly from computer ports or desktop USB hubs without requiring additional power outlets. The 3.5w consumption has minimal impact on electricity bills, and the 200ml tank provides moisture throughout a standard workday with perhaps one refill. The various colour options allow coordination with office decor, while the lightweight 140g construction enables easy repositioning between desk areas as needed.

Vehicle and Travel Versatility

The humidifier's car compatibility comes from its DC5V input that works with standard vehicle USB ports or 12V-to-USB adapters. During long journeys, the 200ml capacity provides moisture for several hours of driving, helping prevent driver fatigue from dry air conditions. The compact 70x66x213mm dimensions fit in most cup holders or dashboard spaces, and the 140g weight means it doesn't add significant load to vehicle weight calculations.

Benefits and Value Considerations

The humidifier delivers measurable advantages through its specific technical specifications and practical design features that address common air quality concerns.

Cost Efficiency and Energy Savings

With 3.5w power consumption, this humidifier uses approximately 0.028kWh during 8 hours of operation, costing less than 1p per day based on average UK electricity rates of 34p per kWh. Compared to larger plug-in humidifiers that typically consume 25-50w, this represents a 85-93% reduction in energy use while still delivering 40mL of moisture per hour. The USB power compatibility eliminates the need for additional power adapters, further reducing initial setup costs.

Comfort and Usability Features

The 200ml water tank capacity strikes a balance between runtime and refill frequency, providing approximately 5 hours of continuous moisture output before requiring attention. The 40mL per hour spray volume creates noticeable humidity improvement in spaces up to 15 square metres without creating excessive condensation on surfaces. The simple operation with single-button control and USB connectivity means setup takes less than a minute, with no complex programming or maintenance requirements beyond regular cleaning.

Practical Reasons for Purchase

This humidifier addresses specific needs for portable moisture control with its 200ml capacity, 40mL per hour output, and USB-powered operation that works from multiple power sources. The compact 70x66x213mm dimensions and 140g weight make it genuinely portable between rooms or locations, while the four colour options provide aesthetic flexibility. For those seeking measurable humidity improvement in personal spaces without high energy costs or complex installation, this unit delivers practical benefits through its specific technical specifications.
