are they electric or mechanical?

Temperature and oil pressure are mechanical. Only the volt meter is electric.

It is ELECTRIC. (have used mine all summer long; it never "walks" around any hard surface or falls over the edge like a lot of the cheap made one's will do, because it's metal blades seem very balanced - no vibration like the rubber/plastic cheap one's out there. It also has 4 little rubber "feet" for even more stability. I love it!)

12 volts. 0.8 Amps. They move a lot of air but are loud. I SAID, THEY MOVE A LOT OF AIR BUT ARE LOUD! Using a PWM with them helps.

They're metal of some sort. Black, matte metal and have a fairly substantial weight for their size. I've had them on since May 2013 and they work great!

They are electric, so you need an outlet, or an external power source such as a generator.

They are plastic. They hold up pretty well but do make a bit of noise going down the sidewalk. The reason for plastic is that it gives the gearboxes some "give" meaning they will slide vs. dig in. This eliminates alot of pressure on the gearboxes.

It is electric! I've been very pleased with this product. It's easy to use and handle. I hope that helps...

I think they'd be fine for gas or electric. I have an electric glass top and they perform beautifully!

No, they are strictly electric. Furthermore, I found them to be undependable, even in short range between adjacent rooms -- sometimes worked, sometimes didn't.

I'm not in the position to look at this moment, but I'm guessing they are plastic. My mother has had no problems with their performance. I suggest you contact Amazon and ask... or, contact the seller.

This is electric. As an aside, I was pleased with it initially but the switch broke very quickly. At first I thought it was the bulb but I replaced it and still nothing. I do still use it for the magnification and am happy with that portion.

yes - all electric. Excellent for avoiding tubing of oil pressure line regularly needed with mechanical oil pressure gauge. -Ryan

They are plastic with a brushed aluminum-like top and bottom. Very lightweight.
