Replacement AC Adapter for Lenovo Z51-70

This 65 W adapter replaces the original Lenovo 45 W or 65 W charger for Z51-70 models including 80K6002QUS, 80K6002RUS, 80K6002SUS, 80K6002YUS and 80K60030US. It delivers 20 V at 3.25 A to power the laptop and charge the battery whether the system is on or off. The unit accepts 100-240 V input at 50-60 Hz for worldwide use.

Upgrade from 45 W Original Charger

Moving from a 45 W brick to this 65 W unit is worthwhile when the original adapter cannot sustain full performance under load or charges the battery slowly. The higher current headroom reduces thermal stress on the power supply during intensive tasks. Users whose existing 65 W charger has failed will restore stock performance without change.

Verify Connector Fit and Voltage Before Ordering

Confirm the laptop requires a 20 V DC barrel connector and that the Z51-70 model number matches one of the listed part numbers. The package includes a 6 ft 2-prong AC cord and a 6 ft DC cord for extended reach. Buyers needing a different tip polarity or voltage should not use this adapter.

Questions about this item

What connector size does the DC plug use for the Lenovo Z51-70 charging port?

The adapter outputs 20 V at 3.25 A through a barrel connector that matches the Lenovo Z51-70 power jack; the 6 ft DC cord reaches the port without strain.

How do I attach the two cords and avoid the common loose-connection mistake?

Plug the 6 ft 2-prong AC cord into the wall, then insert the DC plug firmly into the laptop until it clicks; the error is leaving the AC-to-brick junction unseated.

When should I replace the 6 ft AC cord or the adapter brick itself?

Replace the AC cord if the 2-prong plug or insulation shows wear; replace the brick if output drops below 20 V 3.25 A or the case cracks.
