USB Humidifier

USB-Powered Ultra‑Quiet Personal Humidifier

This compact USB humidifier delivers a steady 10–20 mL / h mist output to maintain optimal ambient humidity for desk setups, laptop keyboards, or small living spaces. Powered solely from a 5 V USB 2.0/3.0 port, it offers instant activation, eliminates the need for external power cords, and provides a silent operation at just 30 dB thanks to a low‑speed magnetic pump and foam‑seal housing. The stainless steel condenser provides long‑term durability while the built‑in hygrometer automatically adjusts mist output based on real‑time humidity readings, ensuring consistent moisture without manual intervention.
