Original Dell 65W AC Adapter for Inspiron 15 (3520), Inspiron 15 (3521), Inspiron 15 (3537), Inspiron 15R (5520), Inspiron 15R (5521), Inspiron 15R (7520), Inspiron 15R (N5110)

works perfectly

I bought a non-Dell charger but it didnt charge the battery. The Dell Adapter does. Yay!

This one works for the Inspiron 3521 because it has the larger tip (7mm). I originally bought a different adapter with the 4mm tip and had to return it. This one comes with both the 4 and the 7 and has worked great so far.

Its nice when you get what you order.

This replaced a lower power adapter that would not charge my computer. This one works great and charges very quickly...I recommend.

This adapter works great...I ordered it for my Dell laptop. I havent had any problems with it. Its a really great charger, I would recommend it for anyone that is looking for a replacement adapter or charger.

I got this charger today. I have been trying to use this charger all day. Well, it will not stay plugged in, and I have to hold it in for it to charge. Even then I have to keep unplugging it and replugged it into the laptop to charge. I bought this because of the good reviews. It may work for someone else but I am sending it back.

Be sure to check if your laptop has a bigger or smaller plug/port. This power cord is for the bigger port on a laptop.

works like a charm.

Not the original charger but works and is in good condition.
