Title: love retractable cables!
Review: 1. it is 34" at max stretch... so to my mind I have 2.5 feet of usable cable. (For some folks, this is not long enough)2. It connects a USB peripheral (like an external hard drive) to a USB port.3. One end is a standard USB end4. One end is called a Mini USB (not to be confused with Micro USB)It is so wonderful to have this small, light multi-purpose cable. I carry multiple external hard drives and now don't have to carry a tangle of cables for them. I love the way it stays all rolled up with just enough length that i need to connect my devices. Works great.* Just be sure you are getting the correct connector. The Micro is smaller than the Mini. The Micro is more common for things like personal Wifi's and bluetooth headsets; the Mini is more common on portable hard drives.I hope this helps!Peace
