The barrel was not stated.

Its actually the older, larger 65W Dell power brick.

Works great!

I was upset when the power supply began to die. My laptop is pretty old and was running really slowly as a result. I was very surprised to find an original Dell adapter for such a good price. It fits and works perfectly and my laptop is working much better. It arrived right on time in good condition. I have no complaints whatsoever on this purchase.

This charger is as pictured and described, an original Dell. I have not had it long, but so far it works well and I would recommend buying a Dell and not a generic replacement as I did that and was not happy.

Product is original as stated and works like it should!! Fast delivery and no hassles. Pay the extra $ and be satisfied!!

Takes twice as long to charge and gets hot if using the laptop while it is plugged in. Good price.

Its nice when you get what you order.

Great experience. Product was exactly what I ordered and works as it should.

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.
