New Genuine 180W 19.5V 9.23A 74X5J JVF3V DA180PM111 Adapter for Dell Alienware 15 R1 R2; Inspiron One 23xx (2350 2320); Precision 15 7000 (7510) 17 7000 (7710); OptiPlex 3011 AIO; M4600 M4700 M4800

Excellent product ... not a substitute.

Im deployed to Afghanistan now but I left my Dell 180W power adapter back at Al Udeid Air Base, Qatar while traveling. My Dell M4800 Precision laptop was mission essential so I ordered a replacement from Amazon and received it in Afghanistan in 10 days!

Works fine. I cant tell the original from the new unit. I can keep my power cord plugged in and move the computer between my at home gym and my office. Perfect.

this is a backup power source so I dont have to unpack the computer bag at home.

Works well with TB19 dock

Arrived with the connector on the plug deformed and cracked. I went to return it today and discovered there is a return window that I just missed. Stupid me, but 1 month seems awfully short.

Dell Precision M4800, had intermittent msg regarding OE power supply not being correct, please plug in correct one. Eventually I noted that battery indicator said plugged in, not charging. Then got msg that battery was nearing the end of its life. So I replaced battery and still had, plugged in not charging msg. I purchased this power supply and was happy to see battery charging. Now I have two working batteries and one working power supply. Yay! Hope that helps you decide what to replace :)

Work very well with my Dell laptop. Work like an original power supply.

Ad Stated Power cord was to come with it. It did not!

Not sure why so many people are complaining about this item? Its exactly as described. Received quickly and very well packaged. After over 10 years of using the 150W adapter stupid Dell sent with my Inspiron 2320, a processor upgrade from an i3 to an i7 forced me to finally purchase the 180W adapter recommended for the system. My old machine is now chugging along happily and no longer complaining about lack of power. Thumbs up!
