Dell PR01X Mini Docking Station for Latitude D-Series/Precision. Original & New. I have shown in the last picture that it works as I used my own cable to test it. It is brand new but doesn't come in original packaging. It doesn't come with a mains adapter charging cable, but you can purchase a PA-10 or PA-13 model adapter off ebay for cheap. Please see pictures and read description before buying. No Returns Accepted.
