Ah, that's why I love you guys. I wasn't even thinking of the voltage difference. I had just kind of fixated on the idea of "how can I plug into the car's outlet?"
Here's what the goal is: I bought a Coleman air mattress the Mrs. and I will use when we go camping. It came with a pump (battery powered) to inflate it. The pump will inflate the mattress (queen size) in just a few minutes. But, it works so quickly because it's more like a "fan" than a high psi pump. You can't inflate a tire or a ball with it for instance.
On the contrary, the tire/ball inflator type pumps (my neighbor's got one of the 300psi models) take 35 minutes or more to fill the mattress. So far, so good, all I want to do is blow up the bed. The catch is, the dedicated pump won't get the mattress quite as firm as we'd prefer. I'm not talking about filled to bursting here, but I'd like a little more. With the higher psi pumps you could inflate until it exploded if you so chose.
Now, that's not only not what I want, it's not an option, as the Coleman doesn't have a valve that would accept the higher psi pump anyway. What I did try though (in the house) was using my Oreck handheld vacuum, set to exhaust. This let me put in the extra few pounds of air I wanted. The problem is that of course, the vac has what I referred to as a "standard" plug, meaning a two pronged affair that goes into the wall. So I guess I can't go this route.
Any ideas?
