Most cars won't see 500w through the lighter port though.

I looked at this to add to a small solar/battery backup system I'm putting together (still need an inverter) and I came across this:

"You cannot draw 500W through a cigarette lighter socket. The socket will overheat or blow its fuse well before you hit 500W. It's physically limited to ~150–180W regardless of what the inverter is rated for."

And it looks like it is maybe 18-20 AWG wire, so I don't think I could cut it and just use a different connector without worrying about a small wire trying to handle 500W
