The cable does exactly what it should. I have therefore my hard drive connected to my LED TV that was "separated" with the enclosed cable from the TV repeatedly. By 2 connection cables now the external HDD gets twice the current, (2x 500mA to 2 USB 2.0 jacks). This will permanently recognized by the TV and I have no more problems. The cable length of 52 cm, see adjusted image, just came right here to me. From me a full purchase recommendation.
