Warnings: Don't leave the cable connected to the phone while unattended. Although the cable should not be recognized by the phone for charging purposes, it is supplying operating power to the phone via its USB port (which is not normally the case). If you are using the cable with no battery in the phone, and if your host computer lost power or shut down, your phone would instantly lose power just like a battery pull had happened. Connect the Micro-B end to the phone first, and then connect the USB A end to the computer. The Micro-B connector is very tiny and we want to make sure it is in the phone straight and seated before you apply power to it by connecting it to the computer. Connecting the Micro-B end first protects your phone and your computer. When working on the phone with the cable connected and no battery inside, best to go ahead and put the back cover back on so you don't lay it down on something that touches some contacts in the battery compartment. If you're working on a proper (uncluttered) workbench and you're the careful type, this may not be necessary, but better safe than sorry. Don't plug this cable into any device not designed for it. If plugged into a device not expecting this map you could destroy the device, your computer, or both. Cable length: about 95cm / 3 ft It has micro USB male and USB male connector
