  • Lengthy delivery time, short cord
    Verified BuyerReviewed by Whyisthisnecessary - December 31, 2017

    Bought an extra power cord so I could leave one at my desk and carry one on the road. The cord took an extraordinarily long time to arrive, so beware if you need one right away. And it was awfully short. I’m sure it gave the specs on the website, so I should have paid better attention, but unless I’m sitting right next to a power outlet, it requires an extension cord. Just another two feet in length would have made a huge difference. I guess I thought it would be the same as the original. Other than that, it works just fine.

    Yes, I would recommend this to a friend.

  • Does not work with other USB-C devices
    Reviewed by maro6613 - March 8, 2018

    Works fine for my laptop, though the cord is a bit short. Must use some proprietary Lenovo interconnect, as it will not charge other USB-C devices. This removes the biggest benefit of USB-C--interoperability. Also, super expensive for a 45W charger.

  • Lenovo USB-C 45W charger
    Verified BuyerReviewed by Krista Rose - April 17, 2020

    [This review was collected as part of a promotion.] Shipped to my house super fast!! Works excellent! I needed a new charger because I dropped my original one in a cup of coffee, was very happy with how fast I got the charger to replace my other one because I need my computer for school!
