90W 20V 4.5A USB Laptop Charger Ac Adapter/Power Cord Supply for Lenovo ThinkPad X1 Carbon 344428U N3N25UK 34442HU L440 Ultrabook, IdeaPad Z510 S210

I lost my original charger so I needed a cheap replacement. This seems to do the trick. The cord feels like it's maybe a bit shorter than the original but not by much. I'm fairly rough with my cables, lots of quick folding up and yanking out of sockets when I need to move classrooms so I'm not expecting a very long life out of it even if I don't lose it again. It's cheap enough to not worry too much about it's lifespan.

I was traveling and lost my power cord for my work laptop. I was in a bind and needed a power cord quickly. The power cord came quickly and worked just like the original that came with my computer completely satisfied with the product. In fact, since the price is right I will get one dedicated to each place I work. Then maybe I won't loose themAgain!

So far so good, Greta deal for the money.Only negative is the fact that the power cord has ground too which is useless for my laptop and makes it difficult to use with ungrounded extension cords.

Over the course of time, the plug on my power cord cracked and didn't adequately recharge my laptop. Had to buy a new one. This product was the right price. It has worked great. No complaints.

Worked perfect and factory OEM quality.

I bought this to replace the old one and it's work. It'a smaller size than the old one.

Forgot my charger at a friend's, this works for the Lenovo yoga 15"

Still not ultra-portable, but a step in the right direction.
