135W USB Square Yellow Tip Adapter

This 135W AC adapter delivers 20V at 6.75A through a USB Square Yellow Tip connector. It is built for Lenovo IdeaPad Y and ThinkPad T and W series laptops that require this specific tip. The unit replaces Lenovo part numbers including ADL135NDC3A and the 45N0052 to 45N0059 range.

Wide voltage input and stepped output

The adapter accepts 100 to 120V at 50 or 60Hz for worldwide mains compatibility. It also supports lower output steps at 90W 4.5A, 65W 3.25A and 45W 2.25A, so one brick covers several Lenovo power ratings. The package includes the adapter and a detachable AC power cable.

Replaces original 135W Lenovo chargers

It directly substitutes the factory ADL135NDC3A brick for the listed IdeaPad and ThinkPad models. The jump is worth it when the original unit is lost, damaged or no longer holds a stable charge. Buyers needing a different connector shape or a higher wattage rating should look elsewhere.
