Fog Fan Desktop Air Cooler with 500ml Water Tank and 3-Speed USB Operation

This desktop fog fan delivers targeted cooling through water evaporation technology, featuring a 500ml integrated tank that provides up to 50ml of evaporation per hour. The USB-powered design operates at just 7W with DC5V 1.5A requirements, making it suitable for student dormitories, office desks, or home workspaces where traditional air conditioning isn't available. With dimensions of 180x180x280mm, this compact unit fits on most desk surfaces while providing adjustable airflow through three speed settings controlled by a brushless motor.

Technical Features and Build Quality

The fog fan combines water cooling technology with adjustable airflow controls to create a personalised cooling solution. From the direct-fill water tank design to the automatic swing mechanism, each component serves a specific function in maintaining comfortable temperatures in confined spaces.

Cooling System Design

The 500ml water tank employs a direct-fill design that allows users to add water or ice cubes without separating tank components, eliminating spill concerns during refilling. This integrated approach means the evaporation system can operate continuously at up to 50ml per hour, creating a cooling mist that reduces ambient temperature through water particle dispersion. The tank's placement within the 280mm tall housing ensures stable operation without compromising the unit's 180x180mm footprint.

Motor and Performance Specifications

Powered by a brushless motor drawing 7W at DC5V 1.5A, the fan operates at 40-50 decibels, significantly quieter than many traditional desk fans. The three-speed settings provide graduated airflow control, while the air supply system maintains consistent output without turning or shaking disturbances. Rated power specifications ensure compatibility with standard USB power sources, including laptop ports, power banks, and wall adapters meeting the voltage requirements.

Construction and Durability

The housing construction incorporates the water reservoir directly into the main body, reducing potential leak points compared to separate tank designs. The brushless motor technology minimises mechanical wear while maintaining the 45-degree automatic swing function that operates without manual intervention. This integrated approach to component placement within the 180x180mm base area contributes to the unit's stability during operation.

Practical Applications and Usage Scenarios

From student accommodation to professional workspaces, this fog fan addresses specific cooling needs in environments where traditional climate control may be limited. The combination of water evaporation and adjustable airflow makes it suitable for various personal cooling requirements throughout different seasons.

Academic and Study Environments

In student dormitories or library study carrels where space is limited and noise restrictions apply, the 40-50db operation allows for concentration without distraction. The 500ml tank provides sufficient cooling for extended study sessions, while the USB power compatibility means it can operate from laptop ports during library use. The 180x180mm footprint fits on crowded desk surfaces alongside textbooks and laptops without occupying excessive workspace.

Office and Workspace Cooling

For office environments where individual temperature preferences vary, this fog fan provides personalised cooling without affecting colleagues. The 45-degree automatic swing distributes air across a wider area than stationary fans, while the manual up/down adjustment allows directing airflow precisely where needed. The white colour scheme blends with most office decor, and the 7W power consumption makes it suitable for continuous operation throughout the workday.

Versatile Placement Options

The compact dimensions allow placement on desks, bedside tables, or kitchen counters where targeted cooling is needed. The side-to-side shaking head function combined with manual vertical adjustment enables users to direct airflow toward specific body areas or across room sections. This versatility makes the unit suitable for summer use in living spaces without central cooling or as supplemental cooling in rooms with inadequate air circulation.

User Benefits and Value Considerations

The fog fan's combination of water cooling technology and adjustable features provides measurable benefits in personal climate control. From reduced noise levels to customisable airflow patterns, each aspect contributes to improved comfort in warm environments.

Long-Term Value Proposition

With 7W power consumption operating from standard USB sources, the fog fan offers economical cooling compared to larger air conditioning units. The brushless motor design reduces maintenance requirements while the integrated water tank construction minimises potential failure points. The DC5V 1.5A power specification ensures compatibility with common power sources, extending the unit's usable lifespan across different locations and applications.

Comfort and Usability Features

The 45-degree automatic swing eliminates the need for manual adjustment while ensuring even air distribution across the immediate area. The three-speed settings allow users to match airflow intensity to their cooling needs, from gentle circulation to more substantial air movement. The direct-fill water tank design simplifies maintenance by allowing quick refills without disassembly, reducing interruption to cooling function during use.

Purchase Considerations

This fog fan addresses specific cooling challenges in compact spaces through measurable performance features: 500ml water capacity providing 50ml/h evaporation, 40-50db operation for quiet use, and 45-degree automatic air distribution. The combination of these specifications creates a targeted cooling solution for environments where traditional fans or air conditioners may be impractical due to space, noise, or power constraints.
