Seiko EM-49 Car Socket Power Strip

This device from Seiko easily falls into the "Why didn't I think of that?" category. The Seiko EM-49 is simply a power strip for the 12V power adapter in most vehicles. It also includes a USB port for charging your MP3 player, cellphone, etc. It goes for a cool $19, if you can find a way to get one over here from Korea.
