Purpose and audience

This 140W AC adapter powers compatible Legion Pro, Yoga Pro, Slim Pro and ThinkPad Z16 laptops. It suits owners who need a replacement or spare charger for daily work and travel. The unit accepts 100-240V input for worldwide use. It delivers up to 140W maximum output through a USB-C connection.

Upgrade context

It replaces a lost, damaged or lower-wattage charger that cannot sustain full system performance. The jump is worth it when the original adapter limits charging speed or cannot run the laptop under heavy load. This model restores the factory power profile without requiring a higher-spec alternative.

Build fit

The adapter plugs into the laptop’s USB-C power port and a standard AC outlet. Its multi-voltage output steps down to 20V, 19.95V, 15V, 9V and 5V for negotiated charging. The compact brick frees desk space and reduces cable bulk in a travel bag. Buyers who need a barrel-tip connector or a higher wattage than 140W cannot use this unit.

Questions about this item

What connector size and voltage does the adapter need to match my laptop?

The adapter supplies 20 V at 6.75 A through a USB-C plug that fits the listed Legion, Yoga, Slim and ThinkPad Z16 models.

Which step do people skip when plugging this charger in for the first time?

They forget to seat the USB-C plug fully until it clicks, so the 140 W handshake never starts and the laptop stays on battery.

When should the cable or brick be replaced?

Replace it if the cable sheath frays near the plug, the brick makes a buzzing noise, or the laptop only charges at 135 W instead of the full 140 W.
