Compatible AC Adapter for Lenovo P51 Workstations

This iTekiro AC adapter delivers 20V at 8.5A for a total of 170W output. It replaces the original Lenovo 135W and 170W adapters supplied with compatible P51 models. The unit includes a 6 ft UL-listed AC cord and a 6 ft DC cord for flexible desk placement. It is built for users who need a direct replacement charger for their workstation.

170W Output Capacity and Limitations

The 170W rating handles the standard charging and operating loads of the supported Lenovo P51 configurations. It does not replace the larger 230W or 300W Lenovo chargers used with higher-specification models. Buyers whose units shipped with a 230W or 300W adapter must select a different power supply. The adapter accepts worldwide AC input from 100 to 240V at 50 to 60Hz.

20V 8.5A Output Specification Decides Fit

The single specification that determines compatibility is the 20V 8.5A DC output matching the 170W requirement. Verify that the laptop's original charger lists this exact voltage and current before purchasing. The connector tip must also match the P51 charging port. This adapter will not power systems requiring 230W or 300W input.

Questions about this item

Will this 170W 20V 8.5A adapter run a Lenovo P51 that originally used a 135W charger?

Yes, it replaces the original 135W and 170W Lenovo adapters for the P51 models listed, but it does not replace 230W or 300W chargers.

How can I confirm the adapter is delivering the correct 20V 8.5A output after I connect it?

The unit includes overload, short-circuit, over-voltage, over-current and over-temperature protection, so the laptop will charge normally and the LED on the DC plug will stay lit when output is stable.

Which cables come in the box and is there anything else I need to buy?

A 6 ft UL-listed 3-prong AC cord and a 6 ft DC cord are included; no extra cable is required for standard wall-outlet use.
