How long does the 230ml tank last?

At 15–20ml per hour of mist, a full tank runs roughly 11 to 15 hours of continuous use. Expect to refill it most days if you run it all night.

What can I power it with?

It takes DC5V/1.1A over USB, so a phone charger, power bank or laptop port works. It draws 4.5W or less, so it is easy on a battery.

How much area will it humidify?

The output is small, so treat it as a personal humidifier for a desk, nightstand or car, not a whole room. A closed bedroom door helps it have any effect.

Does it shut off when the water runs out?

The listed specs do not mention an auto shut-off or empty-tank cutout. Check the unit before leaving it running unattended.

What comes in the box?

The humidifier and one USB cable. No wall adapter is included, so you supply your own USB power source.

Does it need filters or distilled water?

Ultrasonic units like this have no filter to replace. Distilled water reduces the white mineral dust that tap water can leave on nearby surfaces.

Our take on the Bedroom Humidifier with 230ml Water Tank

This is a small ultrasonic humidifier with a 230ml tank that runs off USB power at under 5W. It puts out roughly 15–20ml of mist an hour, so a full tank lasts about half a day of continuous use. It suits a desk, nightstand or car cup holder where a full-size room humidifier is overkill. Against larger ultrasonic models it trades tank size and run time for portability and low power draw.
