The Joujbail 4-in-1 unit is designed to function as a personal fan, humidifier, and ambient night light. It features a 1000ml polypropylene water tank, which is semi-transparent to allow for easy monitoring of water levels. The chassis is constructed from ABS plastic, providing a lightweight yet durable frame for desk use. Its power requirements are met by a 5V/2A USB-C input, which generally requires a high-output wall adapter for consistent performance.
This model utilizes ultrasonic oscillators to create a mist that provides immediate perceived cooling in dry environments. To maintain the quality of the mist and prevent mineral buildup, specifications suggest regular cleaning of the ultrasonic transducers. The internal evaporative filter is made of cellulose honeycomb, which should be replaced every few months to ensure the air remains clean and odor-free.
Practical use indicates that condensation can occasionally pool on the front louvers; placing the unit on a water-resistant surface is a helpful habit for home organizers.
Features include a versatile 2-8 hour timer and three distinct wind modes. This unit does not utilize a compressor, so its effectiveness is highest in regions with low humidity. In these conditions, it offers a localized cooling effect for a single user at a desk or bedside. The built-in light provides a soft ambient glow, adding functionality beyond simple air movement.
If you need a unit that offers wide-angle oscillation to cover a larger area of a room, consider the Topritt 120-degree oscillating model.
