Yes, but the problem is that the "repeater" in the cable, which is actually a hub, also uses the same power feed and the USB port in the computer might not be able to provide all that. I think that the best solution is to connect a small USB hub to the computer and connect a 5V power supply to it. Now, you can use a 5 meter regular (passive) USB cable to the wifi device and all power will be provided by the separate 5V PSU. Select a hub that comes with a PSU or use a DC-DC converter.
