CERRXIAN15cm 65W PD USB Type C Female Input to Slim Tip Power Charging Cable for Lenovo Thinkpad E440 E450 E550 E560 T430 T440 T440S Lenovo Yoga 13 Yoga 11S(Square s)

I have some new Lenovos, 730s that use the USB C power adapter, 65 watts. I bought some older Thinkpads that use the older adapter. It works PERFECT. I didnt need to buy new power adapters.

Charges my Lenovo as intended to

This little adapter does what it promises to do: it connects my thinkpad to a usb-c charging cable.

The lenovo plug has a 560 ohm resistor on it. This means the notebook will expect that the power supply can provide 90 watts.The Type-C negotiation is only for 60 watts. If your laptop tries to use full current, your power supply might shut off unexpectedly. If it's a poorly-designed power supply then it might be damaged. A good one will survive. It's still annoying and wrong.

Works great in an older yoga 11s!

Works great.

It does what it says it does but the quality isn't the greatest. I really is difficult to connect and disconnect from my cables, it feels a bit cheap, and it seems to really struggle to stay consistently at 65W. Would recommend looking for a 100W option if you can find one because the inconsistency can cause your laptop to freak out while charging. But overall, it still does the job about 80-90% of the time and the price is good enough for quick and dirty use that I can't be too mad.

I really hoped this would work, but no luck. My Lenovo doesn't even recognize it's plugged in. Will have to look for other options.
