My Inspiron laptop requires a 130W charger. I received 3 chargers which did not work in my laptop due  to low wattage, one charger was only 65W. The third charger cord did not fit in my laptop. It was also too loose.  Customer service and the language barrier was a nightmare. Between the language barrier and being sent to different departments, I discovered one department does not know what the other one was doing. After several hours on the phone, I gave up and decided to eat the $177 charge. I would advise anybody to stay away from Dell products, the experience is a waste of time. Dell cares more about selling than service.
