This is a Genuine HP 120W Laptop Power Supply AC Adapter 19.5V 6.15A with Power Cord for HP Docking Stations or HP Laptop Notebook Computers. 

This Power Adapter is used but is in good condition. It works well. It has the large barrel connector with center pin in it. It has large tip connector. It is NOT compatible to the HP small blue tip AC power adapters. Please see the photos for the connector to make sure it is compatible to your laptop. I put detailed photos to show the connector. Won't accept return if buyers find it is not compatible to their laptops.  

These are genuine HP products. I have multiple units for sale. 

Because of the shipping fee is a major part of the transaction, I couldn't take returns for this transaction (because the shipping and return shipping fee will be more than the price itself). So, no return please. But I can guaranty that it works well and is in good condition. Thank you.
