If you’re like me, you have a TON of those old “circular tip” shaped Lenovo Power Adapters. They were used for the ThinkPad laptops like the ThinkPad X201T convertible tablet/laptop.
I have 6 of these old adapters & as a result, I’ve been using these 3rd party adapters that convert these old style power adapters to the new interface used by the ThinkPad X1 Carbon Touch.

Here’s the listed specs. I don’t anything about this company. All I know is that I bought 4 of these and they all work beautifully with my old power adapters. Saves me a ton of money by reusing my old accessories on my new laptop. I leave them around at the office, home, and in my bag now.
