I bought this for my Dell Inspiron 7000 series (17-7778 to be exact). There is no doubt about it. However, there are a few problems: 1) The laptop gets very hot after using this charger. I even have problems with the sound. When I turn this off my audio works fine but when I use this charger there is noise in the audio. 2) The laptop power plug is very loose. Often falls when lifting the laptop. I think this charger will definitely not work for my laptop for a long time. Buy a genuine Dell charger. A bit expensive but safe way. Edit: 11/12/2019 And now the charger has stopped charging the laptop. Big. After only a few weeks of work, this product failed miserably.
