This Lenovo 45W USB-C AC adapter supplies up to 45 watts to compatible ThinkPad and Yoga models. It accepts a wide input range and delivers power through a USB Type-C connector.

Check your laptop before ordering

Confirm that your machine uses USB-C charging and matches the listed part number 4X20M26252. Verify the required voltage profile of 20V, 15V, 9V or 5V is supported by your device. The package includes a three-prong North American power cord.

Heat, noise and power draw

The adapter runs silently with no moving parts. It draws between 110V and 240V from the wall and converts it efficiently to the selected output level. Normal operation produces only modest warmth.

Both laptops negotiate automatically; the adapter supplies 20 V at 2.25 A, 15 V at 3 A, 9 V at 2 A or 5 V at 2 A, and the device chooses the correct profile.

What does the 45 W rating mean when the adapter is connected to a T470S?

It delivers up to 45 watts total, allowing the T470S to charge at full speed while running typical workloads.
