What's the purpose of this? Are you trying to connect different devices for media purposes or for charging? If it's for charging I would just use a Cigarette lighter adapter with multiple USB ports like this one.

I would check the cigarette lighter fuse first though, If i'm not mistaken it's a 7.5 amp fuse but I could be wrong.
