Here’s what I’m using in our van to power our GPS, XM radio, and charge up an iPhone or two. =)  (That leaves another spot in case we need to pull out a DVD play or something.)

I got mine from Wal-Mart, but click on the first picture to go to a website I found that has it. (No, I don’t get a cut of the sale.. lol)

Here’s a few pictures of mine to see what it looks like with the light off.  Mine doesn’t glow quite that blue when it’s on.
