65W AC Adapter for Lenovo Yoga C640

This 65-watt AC adapter is built as a direct replacement for Lenovo 45W and 65W chargers used with Yoga C640 models such as 81UE001EUS, 81UE001FUS and 81UE001GUS. It powers the laptop and charges the battery whether the system is on or off.

Replaces 45W and 65W Lenovo chargers

The unit substitutes Lenovo part numbers ADP-45DW B, ADP-45DW C, PA-1450-55LL, PA-1450-55LN, PA-1450-55LR and SA10M42771. It does not replace a 90W Lenovo adapter, so buyers needing that higher output should look elsewhere.

20V 3.25A output with 6 ft cords

Output is 20 volts at 3.25 amps, delivering up to 65 watts through a 6-foot DC cord. A 6-foot 2-prong AC cord rated for 100 to 240 volts at 50 to 60 hertz provides worldwide input compatibility without an extension lead.

Questions about this item

What are the dimensions and weight of the iTekiro 65W adapter brick itself?

The brick measures 4.25 x 1.89 x 1.18 inches and weighs 10.8 oz, so check that your bag pocket or dock shelf can accommodate that footprint.

What is the correct order to connect the two cables and the barrel tip to the Yoga C640?

Attach the 2-prong AC cord to the brick first, plug that into the wall, then insert the DC barrel tip firmly into the laptop; reversing the sequence can leave the tip loose.

When should the 6 ft AC cord or the 6 ft DC cord be replaced due to wear?

Replace either cord if the insulation frays, the 2-prong plug bends, or the barrel tip becomes intermittent, as the internal safety circuits cannot protect against damaged cables.
