Rated 5 out of 5 by from Extra power supply for my new Lenova Yoga LaptopWorks just as it supposed to. I will carry it in my computer case so I don't have to constantly unplug the power supply that out of the original box. I love my new laptop and the power supply works great with it.

Rated 5 out of 5 by from Just like the one that shipped with my ThinkPadIt's a power adapter, same as the one that ships with the Thinkpad X1 Extreme Gen 2. Works as expected. Not much else to say about it.

Rated 5 out of 5 by from Slightly bigger than expected.Great packaging and works as expected. It is bigger than the one that came with the computer, but I bought it to leave on my desk and the other stays in my pack, so it doesn't really matter that it's bigger. It shipped from China so it took a few weeks to come in.

Rated 5 out of 5 by from Get a backup charger!Well, I guess the main thing is - it works, just like the 135W charger that came with my laptop.I've found that it's just great to have 2 sets of chargers for my laptop, so that I can have one that lives at home and one that lives at work - that way, you never forget it, and you never have to haul it. I've never looked back!

The NEWER version is flat and lighter.

Rated 5 out of 5 by from Spare Power Supply Makes Life EasierI like to have a spare power supply for travel, or for moving from the living room to the family room. It's so much easier to unplug from the laptop than to unplug from the wall, and then I don't have to carry both the AC adapter and the laptop. This works just like the one that came with my new laptop, even though it looks a little different. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Spendy, but only option that worksI tried multiple third-party or universal chargers for my Lenovo Y70 Touch, and they all barely worked or didn't work at all. The official charger costs twice as much as many of the other options, but it's the only one I could find that really works. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from The charger is fine, but should sell slimmer oneThe new Lenovo X1 Extreme comes with a slimmer, lighter charger, but the company doesn't sell that one separately, so you end up with the larger, heavier one which is not as portable.

Rated 5 out of 5 by from Very good charger.I purchased this charger for my P1. It is on the small side and charges my laptop fully within an hour and half. I have not detected it getting too hot as some chargers do. It was a good purchase. I recommend this charger. The advantage of buying from Lenovo is that you are not getting a cheap knock off and you have Lenovo to back it up. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Totally averageI got this as a spare power brick for my X1 Extreme. It's a totally standard adapter for Lenovo but isn't nearly as sleek as the original. I understand that they're going for the average size, but it's definitely bulkier than it needs to be. Otherwise it's a totally fine DC adapter. And Lenovo makes pretty good ones all things considered. Definitely better to go with one of these than a cheap Chinese unit.
