Portable Mini Ultrasonic Humidifier for Desk and Car

Yes. It runs on plain water or water with a few drops of essential oil, which is what makes it an aroma diffuser as well as a humidifier. Use only a few drops, and rinse the tank with water after each oil session so the nozzle stays clear. Never run it with an empty tank.

That is the whole idea. The body is palm-sized and sits in a cup holder next to your coffee. Seal the top cap and fill the tank before you set off, then let the mist rise in open air.

Set it on a flat, dry nightstand away from bedding, with air moving around it. Check the tank level before you turn in, and keep the soft yellow LED in view so you know it is running. Do not let the tank run dry.

A room humidifier stays in one room, and a water bottle adds no mist at all. This one fits a cup holder, charges over USB, and carries your oils wherever you go. If you already keep a home fragrance diffuser at home, this one covers the car and the desk.

Plug the USB cable into the port on the base, and the LED confirms the connection. Run time depends on how long you keep it misting, so keep the cable in your bag or car and top up the tank whenever the level drops.

Think of it as a second device for the places the big one cannot follow: the commute, the hotel room, the passenger seat. One body covers the desk, the cup holder, and the nightstand, so you are not buying three gadgets to solve one dry-air problem.
