Greater than one weekItem 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.

> 3 dayThis 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.

> 3 dayWorks great. I bought it as a back up and have used it heavily cause my original got left half way across the country at one time. It has taken a beating and has been a good replacement as needed.
