The Vidihill personal cooler is built for extreme portability, utilizing a 5V USB-C interface that can be powered by a standard wall brick or a portable power bank. This makes it an option for localized cooling at a desk or while traveling. The chassis is made from injection-molded ABS, while the 700ml tank uses polypropylene. These materials provide a sturdy build for daily household use, though placement in direct sunlight should be avoided to preserve the plastic's integrity.
A primary feature of this model is the three ultrasonic misting nozzles. These nozzles provide an immediate cooling sensation in dry air; however, the practical reality is that they are susceptible to "white dust" or clogging if used with hard tap water. Using distilled water and performing weekly descaling with white vinegar helps maintain the flow and extends the life of the piezoelectric elements. The unit also includes a timer with 2, 4, and 8-hour settings to help manage operation times.
- Compact footprint designed specifically for personal zones and desktop use.
- Quiet operation levels are maintained through a DC brushless motor.
- Adjustable speeds allow users to find their preferred level of airflow.
Tests show that the unit provides a localized temperature drop in areas with low humidity. For best results, the water level sensor should be kept clean to ensure the auto-off logic functions correctly, preventing the pump from running while dry. This personal fan is a helpful tool for creating a more comfortable workspace without affecting the entire room's temperature.
For a personal unit with a larger 1000ml reservoir, the Joujbail 4-in-1 cooler offers longer intervals between refills.
