Works on USB 2.0 and USB 3.0
on January 23, 2014
This is a well made, sturdy, albeit somewhat thick cable.
I bought it so that I could extend both USB 3.0 and USB 2.0 cables. I.E., you can plug this cable into a USB 2.0 port on a computer and attach a USB 2.0 device or cable to the other end and it will work fine.
To be clear: you can attach a USB 2.0 phone cable to this extension cord, plug it into a USB 2.0 port on your PC and you will be able to both charge your phone and transfer data to and from it (at USB 2.0 speeds).
You can, of course, also plug this cable into a USB 3.0 port on a computer and plug a USB 3.0 device or cable into the other end and it will work fine.
Posting this info since some other reviewers were questioning this. The USB 3.0 standard is designed to be backwards compatible with USB 2.0 (and even USB 1.1).
The USB 3.0 connector is designed so that the extra pins needed for USB 3.0 are recessed, and they won't be used if the cable is plugged into a USB 2.0 port.
USB 3.0 is a superset of USB 2.0, so why not purchase an extension cable that will serve both types of devices and ports?
