Fast fulfillment and response to questions. I ordered a replacement cord from another seller that was supposed to have the small connection to my laptop and it came with the large one. Very pleased with the accurate description! I'm using this for my Dell Inspiron 7706 2 in 1.**This 90W adapter performs the 'recommended charge level'. SOME docking stations will connect with the 'flat' connector but do not fully power/charge the device. I connected with a docking station from a previous laptop wherein I discovered the charging deficiency with the 7706 2 in 1. I'm leaving the docking station in place to connect to the rest of my devices and ordered this 2nd charger to stay at the workstation fully powering the laptop...much cheaper than buying another docking station.
