Portable Rechargeable Projection Humidifier: Dual Spray System Delivers 40mL Moisture Per Hour with Rotating Night Light

This portable humidifier combines measurable humidification performance with atmospheric lighting in one compact unit. The dual spray system delivers approximately 40mL of moisture per hour from its 1000mL water tank, addressing dry air in bedrooms and small spaces effectively. With a rechargeable 2000mAh lithium battery providing up to 1.5 hours of continuous operation, and a rotating projection night light offering three colour modes, this device eliminates the need for multiple separate units while maintaining portability through its 150mm×150mm×134mm dimensions.

Technical Specifications and Construction Quality

The projection humidifier incorporates specific materials and engineering approaches that contribute to its performance and durability. From the ABS structural components to the precise electronic controls, each element serves a measurable function in the device's operation.

Compact Design and Material Composition

Measuring 150mm×150mm×134mm, the humidifier maintains a compact footprint suitable for bedside tables, desks, and small rooms. The housing utilises ABS plastic for structural rigidity, PP (polypropylene) for chemical resistance in humid conditions, and PC (polycarbonate) for transparent elements requiring thermal stability. These material choices ensure the unit withstands regular use while maintaining its 1000mL water capacity without leakage or structural compromise.

Electrical Performance and Battery Specifications

The 18650 lithium battery provides 2000mAh capacity with a 3.8-4.0V operating range, requiring approximately 3 hours for full charging via the included DC5V=2A USB cable. During operation, the lighting function draws about 600mA (3W) while the spray function uses approximately 500mA (2.5W). These specific electrical characteristics enable the device to operate for about 1.5 hours when both functions operate simultaneously at full capacity after complete charging.

Construction Details and Durability Features

Electronic components are protected from moisture exposure through sealed compartments and proper insulation. The 1000mL water tank incorporates clear viewing sections for monitoring water levels, while the dual spray mechanism utilises precisely calibrated nozzles to deliver the specified 40mL per hour output. The rotating projection mechanism operates on a low-friction bearing system that allows smooth 360-degree movement without excessive power consumption from the battery.

Practical Applications and Usage Scenarios

This portable humidifier serves multiple functions across different environments and user needs. From bedroom comfort to creating atmospheric spaces, the device's specific capabilities address concrete requirements in various settings.

Bedroom Humidity Control and Sleep Environment

In bedroom settings, the humidifier addresses dry air that can cause throat irritation and skin dryness during sleep. The approximately 40mL per hour moisture output maintains comfortable humidity levels in spaces up to 20 square metres when placed centrally. The rotating projection night light offers white, blue, or yellow lighting options at adjustable brightness, creating relaxing atmospheres without the harshness of standard bedside lamps. The intermittent spray mode (5 seconds on, 3 seconds off) provides gentle, consistent humidification throughout the night while conserving battery power.

Office and Workspace Applications

For home offices and workspaces, the compact 150mm×150mm×134mm dimensions allow placement on desks without occupying excessive surface area. The humidifier counteracts dry air from heating and air conditioning systems that can cause eye irritation and respiratory discomfort during extended work periods. The rechargeable battery enables cord-free operation for up to 1.5 hours, allowing temporary relocation to different areas without power outlet constraints. The projection light's rotation function creates subtle background lighting that reduces screen glare without distracting from primary work tasks.

Versatile Lighting and Atmosphere Creation

Beyond humidification, the device serves as a versatile lighting solution for various scenarios. The three colour modes (white, blue, yellow) combined with the rotating projection create dynamic lighting effects for relaxation spaces, meditation areas, or children's rooms. The transparencies included in the package allow customisation of projected patterns, while the adjustable spray modes enable users to balance moisture output with lighting preferences. This combination of functions makes the unit suitable for creating specific atmospheres for reading, relaxation, or background ambiance during social gatherings.

Measurable Benefits and Long-Term Value

The projection humidifier delivers concrete advantages through its specific performance characteristics and construction quality. From immediate humidity improvement to extended durability, these benefits translate to practical value for users.

Cost Efficiency and Operational Value

The rechargeable battery eliminates ongoing battery replacement costs, with the 18650 lithium cell rated for approximately 500 charge cycles before capacity reduction. Compared to operating separate humidifiers and night lights, the combined device reduces electricity consumption by approximately 30% through shared components and efficient power management. The 1000mL water capacity minimises refilling frequency to approximately once per 25 hours of continuous use at the 40mL per hour output rate, reducing maintenance time while maintaining consistent performance.

Comfort and Usability Advantages

The dual spray system's adjustable modes allow customisation based on room size and humidity requirements: continuous dual spray for rapid humidification, intermittent spray for maintenance, or single spray for minimal moisture output. The projection light's colour options provide specific lighting effects: white for general illumination, blue for calming atmospheres, and yellow for warm, relaxing environments. The rotation function adds dynamic visual interest without requiring manual adjustment, while the compact dimensions ensure the unit fits in constrained spaces without sacrificing its 1000mL water capacity.

Reasons for Purchase Decision

This humidifier justifies purchase through its measurable performance specifications: 40mL hourly moisture output, 1.5 hours continuous battery operation, and 1000mL water capacity in a 150mm compact design. The rotating projection night light adds functional versatility without increasing dimensions or power consumption significantly. For users seeking effective humidification with atmospheric lighting in one portable unit, these specific capabilities provide concrete solutions to dry air discomfort and lighting needs in bedrooms, offices, and small living spaces.
