Portable 500 ML USB Humidifier
The KASYDoFF mini humidifier holds 500 ML of water and measures 3.3 × 4.9 × 5.3 inches. It draws power from any USB port, so it fits on a desk, nightstand or travel bag without needing a mains adapter. The compact footprint makes it practical for personal use in bedrooms, offices or near plants.
Two Mist Modes With Auto Shut-Off
Continuous mist runs for up to 750 minutes on a full tank, while the intermittent setting (3 seconds on, 3 seconds off) extends operation to 1150 minutes. A built-in timer powers the unit down after 9 hours of continuous use to prevent dry running. The sealed tank design stops leaks when the device is moved or tilted.
Near-Silent Ultrasonic Operation
The ultrasonic transducer runs quieter than a library, so it does not disturb sleep or work. Optional colourful lights can be toggled independently, including a light-only night-light mode. The ABS plastic shell stays cool during normal use and the USB power draw remains low.
