Rated 5 out of 5 by from Good travel-size charger 90W lightweight, perfect for travel. Do beware that on higher-end models this charger will not keep up with battery draw while using the laptop. I use it to recharge during idle time while traveling.

Rated 5 out of 5 by from Great, helpful personnel and quick shipping. After shorting out the computer plug end of my original charging cord I went on Lenovo's website in search of a new charger. After a brief chat with a very helpful person I had a new cord on the way to my office. The new cord works great and is an exact fit.

Rated 5 out of 5 by from Charges quickly When I need to charge my laptop, it charges quickly and the adapter doesn't heat up that much even when it's being used for an extended period of time.

Rated 5 out of 5 by from Too Big and Too Heavy! Too big and Too Heavy for such a beautiful and light laptop from Lenovo. X1 Carbon is great, but the whole experience is destroyed by this big and heavy charger. Design team should better talk with each other before making a product.

Rated 5 out of 5 by from Replacement power adapter I had an aftermarket adapter that broke at the connection for the AC cord. After looking on Amazon and finding horrible review and nondescript descriptions I decided to shop direct. Tech support was great in helping me find the correct adapter for my laptop. It works great and very well constructed.

Rated 5 out of 5 by from Lenovo Thinkpad 90W AC Adapter (rectangle tip) Great AC Adapter! The 90W is powerful enough to use with the Docking Station or for standalone use as well (seems to be a quicker charge). Regardless, it is well made and a quality product.

Rated 5 out of 5 by from Efficiency at its finest. My old charger burnt out on me, and was having a hard time locating same product. Chat rep helped a lot made it quick and easy to purchase. Got it fairly quickly as well in the mail.

Rated 5 out of 5 by from Amazing battery life! I am not accustomed to writing reviews and replying to company surveys; however, I was keen to write this review of my new T550 to pass on to others my surprising discoveries with this computer. I work as a translator and the most important features for me are a good keyboard and a better than average battery life. I have owned two other “top brand” laptop computers in the past. Both of them were inadequate in terms of keyboard. To be honest, I had not done any research on either and I bought those computers based solely on speed and screen resolution and brand. This time around I did a significant amount of research on the internet before making my purchase. I have certainly not been disappointed by the keyboard on my new T550. It is extremely comfortable with responsive keys that facilitate accuracy and speed. I opted for a 256GB Solid State Hard Drive and 8 GB Memory, so I am more than satisfied with the speed of my T550. Leaving the best for last, and this really is the icing on the cupcake, the surprise has been the battery life. I upgraded the battery to an Integrated 3-cell (44Wh) All the sites that I researched, and the Lenovo site itself, gave the battery life for the T550 at between 10 and 14 hours. I figured that even the bottom of this range would suffice. The thing is: I am tired of fighting for a seat next to an electricity outlet. Surprise, surprise: I actually can’t believe it still, and I have waited before rushing to write this, I have had my new T550 for over 2 months now and I regularly get over 24 hours of battery life.!!! How? I simply work only on 75% brightness! I am not employed by Lenovo so I certainly cannot, and am not, giving any kind of warranty. You should check with your dealer whether this is a freak or a normal situation. Anyway, I am over the moon with this performance. The only minor disappointment with my new T550 is that I added few dollars for a Fingerprint Reader; however, when I downloaded Windows 10, this function was disabled and I have been unable to reactivate it. Perhaps I will have more time soon to try and get my fingerprint reader to work. I hope you find this review helpful. Owen Lewis

Rated 5 out of 5 by from Extra AC adapter One should always have an extra AC adapter for their mobile devices. I have one permanently connected in my work space and I travel with one. Because I have had such great support from the people at Lenovo, I am happy to order from them.

Rated 5 out of 5 by from Very sleek and durable Works great and very sleek not bulky. It was delivered quickly and the box allowed it to be well protected. The website was user friendly and showed a range of options, styles, and colors. The cord easily wraps up and has a velcro strap that allows for easy setup and storage when finished using.

Rated 5 out of 5 by from Good Charger for New Generation of ThinkPads This is the best charger you can buy for the newer ThinkPads - if yours uses this type of plug instead of a barrel connector, this is the charger you need. It charges my X1 Carbon in a couple of hours and I haven't had any issues with it in the last 2 years. I have one at the office and one at home. I order these for end users that need a faster charger or want one for travel - it's no heavier than other laptop chargers, and it fits in normal laptop bags. Not sure why people are complaining about the size/weight; I can carry this in my back pocket without any problems.

Rated 5 out of 5 by from BEWARE!! Does not work for P50 I purchase this item for my Thinkpad P50 and it does not power it. I later purchased another charger and it works so it is not a laptop issue. The description clearly says P50 is supported and that is not the case.

Rated 5 out of 5 by from great product So this was to replace a lost power source. Product is great but the Lenovo order/ship system is very confusing. First it told me it had shipped, with no shipping info, then i got another email after that that said that it was delay with nothing else. Then it was delivered when it hadn't been and then it was delivered the next day. I understand what is going on with shipping logistics but these were not a clear informational emails at all.
