The second question is... They used small handheld smoke machine which was not connected by cable to anything... I thought you need a power to operate a smoke machine...

What are the uses of smoke in movies (instead of creating beams of light)?
If there are any light sources in the frame, even soft ones, they will glow in a hazed set, increasing aerial perspective in the space (background fades into haze more quickly). The contrast will be lowered, but dimensionally. Colors and background detail therefore will be softened. And of course, occasionally a hard source will appear in the frame, like a flashlight, or a door or window opening and a shaft of sunlight crossing the room, etc. You want the hazed look established even if only in a few shots will a beam appear.
I tend to haze bars even though most don't allow smoking anymore, they just look too clean and pristine otherwise... which also brings up that a hazed set can feel "dirtier" as if the room is dusty, useful in old garage or attic scenes.
Haze tends to add drama mainly because it shows off every source off-camera that is not frontal, therefore forcing one into a more dramatic, single-source lighting approach lest the frame ends up looking cluttered and washed-out from too many beams crossing the frame.
Some small hazers I believe just need to be heated up and then can be disconnected from power for some time. And then you have those big ones that can be gas powered like lawn mowers but they have to be used outdoors, and they are very loud.
