I ran across this on Amazon. A dual connector USB cable with a USB A male connector on one end for a computer or USB charger and both a USB Mini and bayonet connectors on the other end intended to fit a Sony early ebook reader (model Prs-600 or earlier) or a Sony PSP-1000, PSP-2000 or PSP-3000 Playstation. Allows charging the early Sony ebook readers from any USB power source and for travel much lighter and less bulky than the original power block Sony provided.
