Mini Desktop USB Humidifier with 300ml Water Capacity and Automatic Shut-Off

This compact USB-powered humidifier delivers precise humidity control for dry indoor spaces and vehicle interiors. The 300ml water capacity provides extended operation with automatic shut-off features that ensure safety and convenience. With dimensions of 73×73×132mm, the unit fits comfortably on desks, bedside tables, or car cup holders while consuming only 2W of power. The seven-colour night light adds ambient lighting that can be customised to suit different environments and preferences.

Features and Quality Construction

The humidifier combines practical functionality with durable construction, featuring ABS and PC materials that withstand regular use. Electronic components are rated for continuous operation, while the atomising system creates fine mist particles that effectively increase humidity levels in small to medium-sized spaces.

Compact Design Specifications

Measuring 73mm in width and depth with 132mm height, the humidifier occupies minimal space while delivering maximum performance. The square profile provides stability on flat surfaces, and the lightweight construction makes it easily portable between locations. The spray mouth is positioned to distribute mist evenly without creating condensation on nearby surfaces.

Power and Performance Data

Operating at 2W power consumption with DC5V=1A requirement, the humidifier connects to standard USB ports found on computers, power banks, and vehicle charging systems. The automatic shut-off function activates after 3 hours in continuous mode or 5 hours in intermittent mode, preventing dry operation and conserving energy when not actively monitored.

Durability and Component Quality

The ABS plastic housing resists impact and daily wear, while PC components maintain structural integrity under continuous operation. The electronic components are rated for the specific 2W power requirement, ensuring consistent performance over extended periods. The atomising piece is designed for repeated use but requires careful handling to maintain optimal mist production.

Practical Applications and Usage Scenarios

This humidifier addresses dryness in various environments, from office desks to vehicle interiors. The compact design and USB power compatibility make it suitable for multiple locations where traditional humidifiers would be impractical or too large for the available space.

Office and Workspace Use

Positioned on office desks, the humidifier counteracts dry air from heating and air conditioning systems that can cause eye irritation and respiratory discomfort. The quiet operation doesn't disrupt work activities, while the automatic shut-off ensures safety during meetings or when leaving the workspace unattended for extended periods.

Home and Bedroom Applications

In bedroom settings, the humidifier improves sleep comfort by maintaining optimal humidity levels throughout the night. The seven-colour night light provides soft illumination without being overly bright, and the intermittent spray mode conserves water while still delivering effective humidity control during sleep hours.

Vehicle and Travel Versatility

The compact dimensions make the humidifier ideal for vehicle use, particularly during winter months when car heating systems create excessively dry air. Powered by vehicle USB ports, it provides comfort during long drives without draining the vehicle's battery due to the efficient 2W power consumption and automatic shut-off features.

Benefits and Value Considerations

The humidifier offers practical solutions for dryness-related discomfort while providing long-term value through durable construction and energy-efficient operation. The specific features address common issues with larger humidifiers while maintaining effective performance in compact spaces.

Cost Efficiency and Operation

With 2W power consumption, the humidifier operates for approximately 50 hours on a standard power bank, making it economical for regular use. The 300ml water capacity reduces refill frequency compared to smaller portable units, while the automatic shut-off prevents water and power waste when the tank empties.

Comfort and Usability Advantages

The simple button controls allow easy switching between continuous and intermittent modes, with the intermittent setting providing 3 seconds of spray followed by 5-second pauses. This pattern maintains humidity levels while extending operation time between refills, particularly useful during overnight use or extended work sessions.

Practical Purchase Considerations

The humidifier addresses specific dryness issues in compact spaces where traditional units are impractical. The USB power compatibility eliminates the need for additional adapters, while the included components provide complete functionality without requiring separate purchases. The automatic timing features ensure worry-free operation in various scenarios.
