This charger quit working after only one week. I was very disappointed to pay a premium price for a product that only lasted 7 days. The process of trying to return the product is also disappointingly slow. So far, I would say you would be better off paying a third of the price for a knock off charger that can easily be returned if it does not work.
The power supply worked as expected. Now my wife has a power supply that stays with her HP docking station at her home office desk and a power supply to keep in her laptop travel bag.
