Extra power supply for my new Lenova Yoga Laptop
Works 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.

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.

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!

Does the job. A little chunky
While completely serviceable, this power supply is not as thin and sleek as the one bundled with the ThinkPad P1 (or X1 Extreme. Otherwise, it does the job, and I'm happy with it.

Not as slim as the one that came with the laptop I ordered at the same time but still a good option to keep at my desk at work.

Spare Power Supply Makes Life Easier
I 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.

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.

The charger is fine, but should sell slimmer one
The 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.

Totally average
I 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.

ThinkPad 135W AC Adapter Slim Tip
I got a second adapter to have one at work and one at home so I don't have to carry it every day. The adapter that came with my laptop has a grounded wall plug with 3 pins while this adapter has 2 pins and is not grounded or polarized. Otherwise, it has the same rating as the original and works ok.

Charger works fine, still unclearof my options
Works great. The only reason I gave it 4 stars over 5 is that I bought it to replace the one that I bought with my laptop (which styled working about a year after purchase when it slid off my bed. This one is bulkier and I think maybe even slower. I had asked for the same one again, so I'm not sure what happened. It works well though and, as usual, Lenovo is my go-to for purchasing laptops etc.

Only authentic Lenovo replacements :)
I've been so hard on the power supply that came with my Lenovo Thinkpad (which I love) that I wanted to purchase a pre-emptive replacement so that I won't have downtime when I eventually completely destroy it (it's bound to happen soon). The nice thing is since the old one does still work, the new one stays plugged in my home office, and now I don't even need to drag one around when I move rooms. Now I think when the old one finally croaks I'll get yet another so I can keep that ease of moving around!
