Compatible Lenovo Z-Series Models

This 65 W AC adapter replaces the original Lenovo 45 W and 65 W chargers for the Z50, Z51 and Z51-70 families, including part numbers 59426435, 80K6002MUS and 80K6002NUS. It delivers 20 V at 3.25 A and accepts 100–240 V input for worldwide use.

20 V 3.25 A Output Decides Fit

The single specification that determines compatibility is the 20 V DC, 3.25 A output rated at 65 W maximum. Your laptop must require exactly this voltage and current; a lower or higher rating will not charge correctly or may cause damage.

Questions about this item

Will the 65 W output actually charge my Lenovo Z51 while I am using it?

Yes, the adapter delivers 20 V at 3.25 A for a full 65 W, matching the original Lenovo 65 W unit so the laptop charges even under load

What does the 100–240 V input range mean for daily use?

It accepts any mains voltage from 100 V to 240 V at 50 or 60 Hz, so the same brick works worldwide without a voltage converter

How much desk space does the 4.25" x 1.89" x 1.18" brick need?

The compact case fits easily behind a monitor or on a power strip, and the 6 ft AC cord plus 6 ft DC cord give plenty of reach without an extension lead
