You did not post the exact model number of your system which would be needed to steer you toward a compatible adapter. And no, I would not purchase a 3rd party adapter as the system may not recognize it and will not charge the battery meaning money wasted. The adapter pic you posted looks to be a very dubious adapter.

Thanks for replying! 

After some searching I found that it's an Inspiron 7573. Is that the same as the Inspiron 7000 7573 2-1? 

I found two chargers on the Dell website, but one is only 45 watts and the other is three pronged instead of two pronged like the one I have. 

Do you know a charger that would work? 

There are two different adapters - 45W for integrated video, 90W if you have discrete video.

Thank you so much! I will look into this later. 

I checked the compatibility using their service tag feature and found the one I needed. Thank you such for your help!!!!
