This is a small 500 ml USB cool-mist humidifier, about 4.7 inches tall, meant for a desk, nightstand or travel bag. It runs in two modes: continuous mist for up to 8 hours, or intermittent mist for up to 16 hours. A low-water sensor shuts it off automatically, and the maker rates it at about 20 dB. It suits one person in a small space, not a whole room. Against larger ultrasonic humidifiers it trades tank size and output for portability and quiet, and it needs a USB power source nearby.

This is a portable mini humidifier with a 500 ML water tank. It is 4.7 inches tall and lightweight, so it fits on a desk or nightstand and can be taken along when traveling. It is powered by USB.
It produces a fine, invisible cool mist to add humidity to the air, which helps with dry skin, chapped lips and scratchy throats in air-conditioned rooms.
It has two spray modes. The first press starts continuous spray for 8 hours. A second press switches to intermittent spray, stopping for 2 seconds at a time, for 16 hours. A sensor shuts the humidifier off automatically when the water level is low, which prevents dry burning. It runs at a noise level of 20 dB.
