Lenovo 45W Original AC Power Adapter Charger

Genuine Lenovo Power Delivery and Precise Voltage Regulation

The Lenovo 45W Original AC Power Adapter is purpose-built to deliver clean, regulated energy to keep your laptop running smoothly. Outputting 20V at 2.25A (45W Max), this genuine power supply brick provides the exact electrical foundation required to charge your laptop’s lithium-ion battery efficiently while powering internal components during daily workloads. Using an authentic original AC adapter ensures precise system handshaking, avoiding non-genuine battery charging warnings and protecting delicate motherboard power circuits from erratic voltage drops.

Integrated Ferrite Core Noise Filtering and Ergonomic Cable Design

Designed for seamless daily usability, this charger features a built-in ferrite choke core on the output cable that actively suppresses electromagnetic interference (EMI). This prevents cursor jitter and touchpad unresponsiveness during charging sessions. The cable is terminated with a durable 4.0mm x 1.7mm right-angle DC barrel jack, which reduces mechanical strain on your laptop’s internal power socket and routes neatly along the side of your desk.

Multi-Layer Electrical Safety and Certified Industrial Construction

Equipped with advanced internal circuit controls, this genuine Lenovo power adapter shields against input over-voltage, output over-current, short circuits, and thermal buildup. Encased in a heat-dissipating, flame-retardant matte black chassis, the unit features heavy-duty strain relief moldings at both cable entry points. Fully tested and certified across global safety bodies—including BIS (IS 13252 / Part 1), UL, CE, UKCA, GS, CCC, and EAC—it offers long-term reliability for students, home office setups, and IT deployments.
