170W replacement adapter for ThinkPad P51
This 170W AC adapter is built for the Lenovo ThinkPad P51 and compatible part numbers including 20HH0008US through 20HH000FUS. It delivers 20V at 8.5A to power the laptop and charge the battery whether the system is on or off. The unit replaces original 90W, 135W and 170W Lenovo chargers such as ADL170NLC3A and ADL170SCC2A. It does not replace 230W, 300W or 330W models.
Thermals noise and power draw
The adapter accepts worldwide input from 100 to 240V at 50 to 60Hz and supplies a maximum of 170W at 20VDC 8.5A. Internal safety circuitry filters input line voltage spikes and surges while limiting output voltage and current to protect the notebook from electrical hazards. A ruggedised case is sealed against moisture and high humidity for reliable operation in mobile environments. High power efficiency provides consistent continuous power during normal use.
Upgrade from lower wattage chargers
This adapter replaces genuine Lenovo 90W, 135W and 170W chargers, making it a direct substitute when the original unit is lost or damaged. The jump is worth it for users who need a single 170W brick that covers multiple lower-wattage part numbers without carrying a heavier 230W unit. It is not for buyers who require a 230W, 300W or 330W power supply for higher-demand ThinkPad models.
