170W 20V 8.5A AC Adapter

This 170W AC adapter supplies 20V at 8.5A through a 5.5x2.5mm barrel connector. It is built for owners of compatible Lenovo laptops who need a replacement or spare charger. The unit accepts a wide 100-240V input range for worldwide use and includes a power cord in the package. It matches part numbers 45N0111, 45N0516, 36200401 and ADP-170BB.

Sustained load behaviour

The adapter delivers a continuous 170W output rated for the listed Lenovo models. It maintains the specified 20V and 8.5A under normal operating conditions for these machines. The design targets stable voltage regulation during extended gaming or workstation sessions on supported hardware. Thermal performance follows the constraints of the original ADP-170BB form factor.

Upgrade context

This unit replaces a lost, damaged or worn original charger for the Y560, Y500, Y500N, Y510P or Y410P. It is not suitable for laptops requiring a different voltage, current rating or connector size. Buyers needing higher wattage for newer workstation models or a USB-C power delivery interface should look elsewhere. The jump is worth it when the original 170W adapter fails or a second charger is needed for travel.

Questions about this item

How much heat or noise does the 170W 20V 8.5A adapter produce during all-day use?

The unit is a sealed brick with no fan; it runs silently and warms normally for a 170W supply under continuous load.

Which power-cord plug must I already have for the EU/US/UK/AU model to work?

The adapter accepts a standard IEC C5 clover-leaf cord; the package includes one cord matching the selected region.

Will the 5.5×2.5 mm tip fit the charging port on my older Lenovo Y560 or Y500?

Yes — the 5.5 mm outer and 2.5 mm inner diameter match the original 45N0111, 45N0516 and ADP-170BB adapters used on those models.
