Product Description

The Lenovo laptop adapter 20V 4.25A is a high‑quality replacement charger designed to power and charge a wide range of Lenovo laptops that require around 85W of DC output.

• Square / slim tip (yellow rectangular Lenovo connector) – common on newer ThinkPad/IdeaPad models

Be sure to confirm which connector your laptop uses before purchase.

Built with high‑efficiency power components and multiple protection circuits (over‑voltage, over‑current, short‑circuit, and over‑temperature), this adapter is designed for daily use in homes, offices, schools, and business environments. The robust power cable and DC lead can withstand frequent connecting and disconnecting, while the compact body makes it easy to carry in a backpack or laptop bag.
