How long does the mist last on one fill?

About 3.5 hours in continuous mode and about 7 hours in intermittent mode, according to the maker. The tank holds 220 ml.

Does it turn off by itself?

Yes. It has auto shut-off that cuts the mist when the water runs low, so it can run unattended overnight.

Can I use it without a USB outlet?

No. It runs from a USB charging cable, so you need a USB port, adapter or power bank. There is no internal battery.

How much space will it humidify?

It is built for a small personal zone such as a desk, nightstand or car seat, not a whole room. Expect it to take the edge off dryness close by.

The maker rates it at 36 dB, roughly a soft whisper. Most people will not notice it on a desk or bedside table.

Does it need filters or special water?

No filter is listed. Use clean water and rinse the tank regularly to keep the mist and the unit working well.

Our take on the LACKUST Portable 220ml USB Mini Humidifier

The LACKUST Portable is a palm-sized ultrasonic humidifier that runs off a USB cable. It holds 220 ml and puts out cool mist in two modes: continuous for about 3.5 hours, or intermittent for about 7 hours. A single button runs everything, and it shuts off automatically when the water runs out. At 36 dB it is quiet enough for a desk or a nightstand. It suits one person in a small space, not a whole room. Against larger tank humidifiers it trades run time and coverage for size and portability.
