How long does the 500ml tank last?

Run time depends on the mist mode. Continuous mode drains the tank faster than intermittent mode, so expect short sessions rather than all-night use. Refill when the mist stops.

Does it shut off automatically when empty?

The product does not list an auto shut-off. Turn it off and refill when the mist weakens or stops, and do not run it dry.

Can I use it in a car?

Yes. It runs on USB power, so a car USB adapter or power bank works. Keep it upright so water does not spill into the base.

How do I change the light color?

A short press of the power button controls the mist. A long press turns on the seven-color gradient, a second long press gives a slow color flash, and a third locks the current color.

Is it good for a large bedroom?

It is a mini humidifier with a small tank and modest output. It suits a nightstand, desk or small room better than a large bedroom.

What do I need to run it?

A USB power source such as a wall adapter, laptop or power bank. The unit itself is the humidifier; the adapter is not listed as included.

Our take on the Tkrady 500ml Cool Mist Humidifier with Nightlight

The Tkrady 500ml Cool Mist Humidifier is a small USB-powered unit with a 500ml tank, one-button control and two mist modes: continuous and intermittent. It runs near-silent, which suits a desk, nightstand or car, and its built-in light cycles through seven colors or holds one. Against larger ultrasonic humidifiers it trades run time and room coverage for portability, and it has no auto shut-off or humidity sensor. It fits small spaces and short sessions rather than whole-room moisture.
