Cigarette lighter broke on my C6

This weekend i had one of those power converters plugged in to my Cigarette lighter to charge my laptop. Not sure if this makes a difference but my radar detector was also plugged in to a spare socket that ther power converter has also. Now i have no power going to my cigarette lighter anymore. I'm wondering if it could be a fuse or something that blew. I look at the fuse box under the hood but it didnt say which fuse is for the cigarette lighter. Any ideas anyone ???
