I can't think of the make/model of the one I have in my car. I've had it for YEARS.
I do believe it's only supposed to be operated continuously for like 5 minutes at a time...but honestly? I have NEVER paid attention to that. If I need to air up my tires with it, I air the tires up until they reach the pressure needed and never pay attention to how long it runs to do it.
They're not that expensive. I don't remember what I paid for mine...but $40 wouldn't be a bad guess. I got it because the cord and hose coil up inside the thing and makes it neat to keep in my trunk. The air hose is a couple feet or so long, the power cord is plenty long enough to reach all the tires on my car from the cigarette lighter in the dash, and the pump has its own gauge on it that has proved to be pretty darn accurate.
Give yourself about a $40 budget, give or take, and go shopping for something that strikes your fancy. Me? If I were to buy another one, I'd probably take a look at the ones Craftsman or AutoZone has in that price range. In fact, I probably bought mine at AutoZone all those years ago. Whatever you get, I recommend two things: you don't get all caught up in all the bells and whistles...you want a basic 12 Volt air pump with a long cord, an air gauge, and a hose/nozzle just long enough to reach from the pump to the tire nozzle. The other thing is that everything coils neatly and suits your storage space well without taking up scads of room or making a mess with loose a cord/hose.
OH YEAH...
Don't forget to buy a tire plug kit and keep it in the trunk, too. An air pump doesn't do much if you can't plug the hole in your tire long enough to get you to a shop for a proper patch/replacement.
EDIT:
I dunno what makes the normal sale price on this one from Walmart worth $235.76, but it's on sale now for $195.80 off (going for $39.96). I like the fact that it comes in a nice case, which would keep a trunk really neat and organized.
