The USB vs the duo link are different connectors. The duo link attaches to your iPhone or iPad slot for charging and the USB would fit in any USB connection. This is the only difference I could make out.
Sorry, there was a problem. Please try again later.The duo-link has both a USB and lightning connection. With both you can transfer pictures, music, etc, from your PC to your iPad or iPhone. The regular USB doesn't work with iPad or iPhone.
