Replacement 170W AC Adapter

This iTekiro adapter replaces original Lenovo 135W and 170W chargers for compatible ThinkPad models. It delivers 20V at 8.5A with a maximum output of 170W. The unit accepts worldwide AC input from 100V to 240V at 50Hz to 60Hz. It is not a substitute for 230W or 300W Lenovo power supplies.

Sustained Load Behaviour

High power efficiency provides consistent and continuous power for your laptop during extended use. Internal safety features filter input line voltage spikes or surges and limit output voltage or current to protect the system from electrical hazards. The ruggedized case withstands harsh mobile environments and offers tight sealing against moisture and high humidity. The adapter powers the laptop and charges the battery whether the system is on or off.

Extra Long 6ft Power Cords

Included are a UL listed 3-prong AC power cord measuring 6ft and a DC power cord also measuring 6ft, providing extended reach without extension cords. The adapter body dimensions are 6.18in x 3.31in x 1.97in and it weighs 26.50oz. This model does not replace Lenovo 230W or 300W chargers, so buyers needing higher wattage should look elsewhere.
