This new NShi adapter delivers 20 volts at 8.5 amps for a total of 170 watts. It uses a square yellow slim tip connector and ships with an AC power cable. The unit is built as a direct replacement for specific Lenovo ThinkPad chargers.

100-240V Input Range

The adapter accepts a wide input range of 100 to 240 volts at 2.5 amps across 50 to 60 hertz. This makes it suitable for use in different regions without a voltage converter. The fixed 20V 8.5A output is designed only for laptops that require this exact specification.

Replaces Multiple Lenovo Part Numbers

It replaces original Lenovo parts such as SA10R16886, 4X20S56697, PA-1171-72 and ADL170SLC3A among others. The upgrade is worth it when the original charger has failed or been lost and the laptop model matches the listed compatible series. It is not for laptops that use a different tip shape, voltage or wattage rating.
