65W AC Adapter for Lenovo IdeaPad

This 65W AC adapter delivers 20V at 3.25A through a 4.0 x 1.7mm connector. It supports a wide input range of AC 100-240V at 50/60Hz for global use. The unit is designed for Lenovo IdeaPad 1, 3, 5, Flex, and Yoga series laptops requiring this specific power rating and tip size. It serves as a direct replacement for lost or damaged original chargers.

Replaces 45W and 65W OEM units

The adapter fits part numbers ADL45WCC, ADL45WCA, ADP-45DW B, and PA-1450-55LL across numerous IdeaPad models. It covers systems from the 110, 120S, 130, 310, 320, 330, 510, 520, 530, and 710 families. The jump is worth it when your original 45W supply cannot sustain full performance or charge under load. Users with a failed 65W brick regain full charging speed immediately.

Stable output during continuous operation

The power supply maintains its rated 65W output during extended charging and high-demand sessions. Built-in safety certifications include CE, FCC, and ROHS compliance for reliable operation. It handles sustained loads without the voltage droop common in lower-rated substitutes. The design targets consistent thermal performance for daily professional and student workloads.

Questions about this item

Will the 4.0 x 1.7mm connector fit my Lenovo IdeaPad 3 14?

Yes, the 4.0 x 1.7mm barrel plug matches the charging port on IdeaPad 3 14 models listed such as 3-14ADA05, 3-14IIL05 and 3-14IML05.

How do I install this adapter, and what step do people often miss?

Plug the AC cord into the brick, insert the 4.0 x 1.7mm tip firmly until it seats, then connect the wall plug; the missed step is not pushing the barrel in fully, which leaves the laptop on battery power.

When will I need to replace the cable or the brick itself?

Replace the cable if the insulation frays near the 4.0 x 1.7mm connector or the AC inlet, and replace the brick if the 20V 3.25A output becomes unstable or the unit overheats.
