The Mini USB Donut Humidifier is one of the smallest portable humidifiers in the world. It's extremely light weight - just throw it into a bottle, vase, pot, container, and watch it crank out cool mist.
With all humidifiers, it helps reduce dust and bacteria in the area and moisturizes your skin to give you instant relaxation. It has an "auto-off" function when all of the water from your chosen container fully evaporates.
This humidifier has a USB plug power supply, low DC 5v input voltage, and can easily be powered by a car charger, PC, or power bank. Take it anywhere you go - whether you're doing yoga, relaxing at the park, working at your desk, or just hanging out at home.
