The Loiosu portable unit is designed for personal, localized use on desks or nightstands. The chassis is constructed from injection-molded ABS polymer, which provides a rigid frame for daily household handling. Tests indicate that while the material is impact-resistant, it may show yellowing over time if kept in direct sunlight. This unit operates via a USB-C interface, allowing it to be powered by standard power banks or laptops for added portability.
Specifications indicate that the cooling mechanism relies on a 500ml water reservoir and synthetic cellulose filters. Practical use shows that the ultrasonic misting discs are sensitive to mineral scaling from tap water, which can lead to clogging. To maintain build quality and ensure the misting function remains consistent, using distilled water is a recommended maintenance step. The inclusion of a 7-color LED array adds an aesthetic element to the workspace without increasing the footprint of the 1.2-pound device.
To prevent biofilm accumulation in the reservoir, specifications suggest a weekly sanitization routine, as the internal tank does not feature an antimicrobial coating.
Features include three fan speeds and a compact design that fits easily in crowded areas. However, because this relies on evaporation, its ability to lower air temperature is dependent on low ambient humidity. In environments where humidity exceeds 55%, the unit primarily serves as a personal fan and ambient light source rather than a cooling device.
For those needing a higher-capacity solution for larger rooms, the Uthfy 5.3-gallon cooler provides extended run times without frequent refills.
