3 in 1 Portable Evaporative Air Cooler with LED Night Light and Humidifier for Desk Use

This compact 3-in-1 portable air conditioner combines a fan, humidifier, and ambient night light into one practical device for personal cooling at home or in the office. Powered by USB, it connects easily to computers, power banks, car chargers, and standard USB adapters, making it useful wherever you work or relax. During hot summer days, adding ice and water to the reservoir helps the evaporative cooler produce a refreshing breeze, while the three-speed fan lets you adjust airflow from a gentle low to a stronger high setting. The built-in 7-colour LED light offers a soft glow that can be used as a small night lamp, creating a calm atmosphere on a desk or coffee table. With a noise output of 45-50dB, it runs quietly enough for sleep or focused work.

Features and Construction

Designed for convenience, this cooling fan uses basic but reliable components to deliver its core functions. The brushed motor drives four blades to move air through the water-soaked filter, and the normal button operation makes speed selection straightforward.

Evaporative Cooling and Humidification

The unit works as an evaporative air cooler by drawing air across a wet pad, which lowers the air temperature slightly while adding moisture to the room. This dual function also helps humidify dry indoor air, which can be beneficial in air-conditioned environments. The effect is most noticeable when the reservoir is filled with cold water or ice, giving a direct, refreshing breeze in the immediate area.

LED Night Light with 7 Colours

The fan includes a small LED light that cycles through seven different colours, providing a gentle, decorative glow. This feature serves as a night lamp and can be used independently if you only want ambient lighting without the fan running. It is suitable for bedrooms, nurseries, or any space where a soft coloured light is preferred.

Size and Practical Fit

With dimensions of 170 x 75 x 240mm, this air cooler is compact enough to sit on a desk, bedside table, or coffee table without taking up too much space. Its lightweight design makes it easy to move between rooms or pack for travel, and the USB power input means you can run it from a laptop while working or from a power bank in locations without mains sockets.

Uses and Placement

This portable cooler is designed for personal use in areas where a full air conditioner is impractical or too large. Its direct-blowing airflow pattern focuses cooling on the user, making it effective for single-person workstations or reading corners.

Office and Desk Work

Place the cooler on your desk to create a focused airflow while you work. The low noise level (45-50dB) means it will not disturb phone calls or video meetings, and the USB power allows connection directly to your computer. The humidifier function can help alleviate dry air caused by office air conditioning.

Home and Bedroom Use

In a bedroom, the unit can be used as a bedside fan with the optional night light for a calming effect. The 7-colour light adds a decorative touch, and the three-speed fan allows you to choose a gentle breeze for sleeping or a stronger flow for cooling down on hot nights. The evaporative cooling function adds moisture, which can be welcome in dry climates.

Benefits and Buying Value

This product offers a practical solution for personal cooling and ambient lighting without the cost or complexity of larger air conditioning units. Its USB power source flexibility and compact size make it a versatile addition to any small space.

Energy Efficiency and USB Convenience

Running on low power via USB, this fan consumes minimal electricity compared to traditional air conditioners, making it an economical choice for targeted cooling. The USB compatibility means you can power it from laptops, power banks, or car USB ports, ensuring it works in many settings without needing a dedicated power outlet.

Low Maintenance and Easy Care

The simple construction of the evaporative cooler requires only regular cleaning of the water reservoir and occasional rinsing of the cooling pad. No specialised tools or filter replacements are needed, keeping ongoing costs low. The Type-C cable is detachable for easy storage or replacement.
