Power Output & Connector

This 170W AC adapter delivers a regulated 20V at 8.5A through a USB Square Yellow Tip connector. It is designed for ThinkPad P, W, T, X1 and Y series mobile workstations that require this specific power rating and tip geometry.

Compatibility Check

Verify that the laptop’s original charger carries a part number such as ADL170NDC3A, ADL170NLC3A, ADL170SCC3A, ADL170NDC2A, ADL170NLC2A or SA10R16886. Confirm the device accepts 20V input and uses the square yellow-tip plug; other ThinkPad models use different voltages or connector shapes.

Sustained Load Behaviour

Built-in protection guards against over-voltage, over-current, over-temperature, short-circuit, over-charging and over-discharge during continuous operation. The wide 100-240V 50-60Hz input range allows stable output across varying mains conditions without derating.

Questions about this item

Does the adapter come with the AC mains cable, or do I need to buy that separately?

The unit ships as a complete charger with the detachable mains lead included; nothing extra is required to plug into a 100–240 V socket.

My laptop needs 20 V 8.5 A — is this the correct 170 W version?

Yes, the brick delivers exactly 20 V at 8.5 A for a maximum of 170 W and uses the USB square yellow tip that matches the listed ThinkPad models.

Will the over-voltage and over-current protection still work after the adapter warms up under full load?

The built-in safety circuits — over-charging, over-voltage, over-temperature, over-current, short-circuit and over-discharge — remain active across the entire operating range.
