The 5V 2W USB-Powered Mini Air Humidifier Kit is a compact, ready-to-use DIY humidifier module designed for small-scale misting and humidification projects. It combines a 20mm ultrasonic atomizer disc with an integrated driver circuit on a single board, powered by a standard 5V USB supply. This makes it an ideal solution for custom humidifiers, aromatherapy diffusers, desktop misters, and DIY electronics projects requiring ultrasonic atomization.
At the heart of the kit is a 20mm ultrasonic atomizer that vibrates at high frequency (typically 108kHz–113kHz) to break water into fine mist particles. The integrated driver board handles the high-frequency oscillation, eliminating the need for separate driver modules and complex wiring. Simply connect the atomizer disc to the driver board, immerse it in water, and apply 5V USB power to begin misting.
The 5V USB power input makes the kit extremely convenient to use — it can be powered from any USB port, power bank, phone charger, or computer. The 2W power consumption is low enough for portable and battery-powered applications, while still producing a visible, consistent mist output suitable for small spaces.
The Type A designation indicates the specific atomizer disc type and driver configuration, optimized for reliable operation and long service life. The atomizer disc is designed for continuous operation when properly immersed in water, with a typical lifespan of 3000–5000 hours.
The kit is widely used in DIY humidifiers, aromatherapy diffusers, desktop misters, miniature fog machines, model-making effects, and educational science projects. It is also popular in commercial product development for small appliances and personal care devices.
The kit includes the 20mm atomizer disc and the integrated driver board, with pre-attached wiring for easy connection. The compact form factor allows integration into small enclosures, bottles, and custom housings.
Important Note: The atomizer disc must be fully immersed in water during operation. Do not operate the atomizer dry, as this will cause overheating and permanent damage. Use clean water (preferably distilled) to prevent mineral buildup on the disc. The driver board should be kept dry and away from water.
Whether you are building a custom humidifier, designing an aromatherapy diffuser, or adding misting effects to a project, the 5V 2W USB-Powered Mini Air Humidifier Kit provides a reliable, integrated solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
