My request is still somewhat unusual. I own a mobile power bank for charging laptops, which unfortunately only one adapter for the old power adapter came with Lenovo (T520 etc.). So I ordered this cable and so that I can now, as you can see in the picture, recharge my Lenovo Helix with my mobile Power Bank. Not only that, in the office I have a number of power supplies of old design and now save a lot of money because I have to buy no 2. PSU.
The quality is very good. and the connectors have a tight fit, so that nothing can be solved.
Therefore I would highly recommend this cable to anyone who has a mobile power bank for charging notebooks without the appropriate adapter or an old Lenovo PSU.
