Portable Mini Humidifier 300ml
This compact USB-powered humidifier holds 300ml of water and fits easily on a desk, nightstand or car cup holder. It is aimed at anyone who wants a personal cool-mist device for a bedroom, office or vehicle without taking up much space.
Simple one-button control and USB power
Press the button once to choose continuous or intermittent mist, hold it for three seconds to toggle the cycling light, and the unit shuts off automatically when the tank runs dry. The only common issue is forgetting to refill the 300ml tank before the four- or six-hour timer ends.
300ml tank gives four to six hours of mist
Continuous mode runs for four hours and intermittent mode stretches to six, which covers a typical work session or overnight use. It will not last a full day without refilling, so users needing all-day humidity should plan for a top-up.

Questions about this item
How can I tell the humidifier is running at the rated 26 dB after I set it up?
Listen for a barely audible hum in a quiet room; the ultrasonic mist should appear steadily in continuous mode and pulse in intermittent mode without any rattling or fan noise.
What comes in the box and what must I supply myself?
The unit includes the humidifier body, a USB power cable and an instruction sheet; you must provide a 5 V USB power source such as a laptop port, car adapter or wall charger.
Which version should I choose if I need the 300 ml capacity in white?
Select the listing titled "Portable Mini Humidifier 300ml White USB Powered" — that exact model delivers the 300 ml tank in the white finish shown.
