I had a charger from a Levono Thinkpad E460 and it charged my used T470s. So I definitely would not run into problems, I bought the new charger for the T470s. The old brick was working, so I am using it with the brick to power port from the charger I bought. The cable didn’t fit snuggly into the brick on the charger that came with my laptop. The cable should offer some resistance to fit securely to the brick to the power outlet. Trying to buy just that cable is a bit to complicated and a waste.
