Desktop diffuser built like a train, with mist rising from the stack

The shape is a classic steam engine and the mist leaves the chimney the way smoke would. Underneath it is a straightforward 300 ml diffuser for dry indoor air. A few drops of oil in the tank and the room picks up the scent as well.

Why choose this mist diffuser?

It runs on USB, so a laptop port or a phone charger is enough. The lighting can stay off if you only want the mist.

Engine styling: a nostalgic locomotive body with mist drifting from the funnel.
300 ml tank: enough water for a long stretch of continuous output.
Two glow settings: warm light or blue light, to suit the room and the hour.
Takes scented oils: add a few drops to the water for a calm or a brighter scent.
USB powered: 8 W over the included USB cable, no adapter hunting.

Fill it, plug it in, and let the engine run.

At 24 x 14 x 8 cm it takes a desk corner, a hallway shelf, or a windowsill. The body is ABS and PP, so it wipes clean and the tank is easy to refill. Coal black and antique brass finishes are offered, and a 3-pack of scented liquid is listed alongside them.
