Compatible ThinkPad Models

This 170 W AC adapter fits Lenovo ThinkPad P71 and W540 mobile workstations. It supplies 20 V at 8.5 A to match the original charger specifications. The unit is intended for owners who need a direct replacement or a spare power supply for these specific models.

Replaces 135 W and 170 W Chargers

The adapter substitutes an original 135 W or 170 W brick without changing the connector or voltage. It does not replace a 230 W charger, so systems that shipped with the higher-wattage unit will not receive sufficient power. The upgrade is worthwhile when the original adapter has failed or when a second charger is needed for travel.

Sustained Load Behaviour

Built-in overload, short-circuit, over-voltage, over-current and over-temperature protections engage continuously during extended use. The input range of 100 to 240 V at 50 to 60 Hz allows stable operation worldwide. A six-foot AC cord and six-foot DC cord give flexible placement while the durable case resists humidity.

Questions about this item

What is the length of the AC and DC power cords on this iTekiro 170W adapter?

Both the UL listed 3-prong AC power cord and the DC power cord are 6 ft long, giving a combined reach of 12 ft from wall outlet to laptop.

How do you connect the adapter to the ThinkPad P71 or W540, and what step is often missed?

Plug the 20V 8.5A DC barrel connector firmly into the laptop's power jack until it seats; the step often missed is ensuring the AC cord is fully inserted into the adapter brick before switching on the mains.

When should the 6 ft AC power cord be replaced?

Replace the cord if the insulation shows cracks, the plug pins are bent, or the connector becomes loose after extended use.
