170W ThinkPad Charger ADL170SCC3A

This 170-watt power adapter replaces the original charger for compatible ThinkPad mobile workstations and gaming models. It accepts a universal 100 to 240-volt input and delivers 20 volts at 8.5 amps through a square yellow tip connector. The unit suits professionals and gamers who need a reliable mains-powered supply for demanding workloads.

Thermals noise and power draw

The adapter operates from standard mains frequencies of 50 to 60 hertz and converts up to 170 watts of output power. Built-in safety circuits protect against short circuit, overvoltage, overcurrent and internal overheating during continuous use. No active cooling fan is fitted, so operation remains silent in typical office or home environments.

Upgrade considerations

This charger replaces lost, damaged or lower-wattage units such as 135-watt models for supported ThinkPad P, W, T, X1 and Legion series laptops. The jump is worth it when the original power brick fails or when a higher-capacity supply is required for sustained performance under load. Buyers needing USB-C Power Delivery or a different connector type cannot use this adapter.

Questions about this item

How do I install the 170W ThinkPad charger and what step is often missed?

Plug the 3-prong AC cord into the brick, connect the square yellow tip to the laptop, then plug the cord into a 100-240V 50-60Hz outlet. The step often missed is fully seating the square yellow tip until it clicks.

What maintenance or replacement will the 170W charger need later?

The AC cord and square yellow tip can wear from repeated bending; replace the cord if the insulation frays or the tip becomes loose. Internal protection circuits handle short circuit, overvoltage, overcurrent and overheating.

What limit appears first when the 170W charger runs under sustained load?

Internal overheating protection activates first if the 20V 8.5A 170W output is sustained in poor ventilation, shutting the unit down until it cools.
