When you need just a little more distance connecting a mobile device to your computer to sync and charge or to your wall charger for power - this cable will extend the reach of your existing USB cable. Enjoy the freedom to add distance to your controller or to place your mouse, keyboards or other peripheral where you want it and not be limited by your existing USB cable lengths. Foil and braid shielding reduce EMI/RFI interference and twisted pair construction helps reduce crosstalk for a high speed, error-free data transfer. USB 2.0 compatible. PC and Mac compatible.
