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)

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.

works like a charm.

Great laptop accessories. Great quality

Lighter than my original charging cable and the tip seems sturdy so it wont bend the wire internally that easily so a good purchase indeed.

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

Great product

This is what I needed for my Dell laptop after original charger stopped charging battery. Works good.

Item is not genuine Dell. It will recharge the battery while th computer if off, but does not provide electricity to the machine while it is in use. So you must deplete the battery, recharge, deplete the battery, recharge over and over. I would pass on this one and pay the extra $15 for a genuine Dell adapter that will both recharge the battery and run the machine. Worthless. Amazon advertised this as Dell compatible, which it is as long as you are finished working when the battery runs out and if you have a few hours for it to recharge. I threw it out.

Charger works as expected, and Ive been using it for about six months or so. A couple of months in (just past the return window), the plastic casing around the prongs that go into the AC adapter cracked, letting the casing fall off. Ive been able to just place the casing back on and keep using it (although it may not be the safest idea), but it is frustrating that it would crack/break without much abuse. More recently, the rubber of the cord tore near the plug, which I simply repaired with electric tape (see attached picture). I use my laptop and charger between home and school, and when coiling up the charger, I take care to leave some slack around the fixed ends as to not put undue stress on the cord or plugs. Irregardless, the charger seemed to be quite fragile compared to my original Dell charger, which lasted without any defects for over two years before I lost it. This leads me to wonder if this is in fact a genuine Dell charger, as the adapter on this charger also heats up significantly more than the original during use. In summary, it does the job, but I cant speak to its durability or whether or not it really is a Dell charger as advertised.

I bought this and plugged it in and still working mine got to the point it was telling me I had the wrong adapter and had the laptop for awhile and it came with it go figure but this is the dell brand and it works great
