How long does the tank last?

The tank holds under 0.5L, so expect short runs between refills. The 2-8 hour timer lets you cap a session, but a full night on high mist will likely need a refill.

Does it shut off when the water runs out?

Yes. It has a water-free power-off protection that cuts the unit when the tank is empty, which guards against dry burning.

Can I use essential oils in it?

Yes. Aromatherapy is one of its listed functions, so it works as a diffuser as well as a humidifier.

How much area does it cover?

It is rated for rooms under 10 square meters. It suits a desk, nightstand or small bedroom rather than a large living room.

What comes in the box?

The humidifier, a charging cable and an instruction manual.

Does it need a power outlet?

It runs on USB power through the cable at the back, so it needs a USB adapter or port nearby.
