The instructions were perused a few times. "It looks easy enough." But, is it?
Yes. Yes, it is. Plug the chord into the cigarette lighter. Check the air
pressure in the tire. Place the tire nozzle onto the tire air hole. Turn on the tire pump. It's a little loud as you can tell by watching the video. But, so what? If you're stranded on a highway at night, you'd want to have a can of fix-a-flat alongside the air pump. That way, you can use that to (hopefully) seal a hole in the tire, then, air it up and get home safely.
