170W 20V 8.5A Power Supply

The Graviton ADL170SDC3A is a 170W AC adapter delivering 20V at 8.5A for compatible Lenovo laptops. It accepts a universal 100-240V 50-60Hz input for worldwide use. The unit includes an 11x5mm barrel connector and ships with a power cord. CE certification confirms compliance with European safety standards.

For Lenovo 170W 20V Laptop Owners

This adapter suits owners of Lenovo models requiring the listed part numbers such as SA10R16882, SA10R16886 or 02DL136. Buyers whose devices need a different voltage, amperage or connector size should look elsewhere. It is not a universal charger for every laptop brand or power requirement.

11x5mm Barrel Connector Fit

The 11x5mm plug size is the critical specification that determines physical compatibility with the laptop power jack. Verify the device service manual or original adapter tip dimensions before purchasing. An incorrect tip diameter or pin configuration will prevent a secure connection and power delivery.
