The Lenovo 4X21J81436 is a 65 W AC adapter designed for ThinkCentre desktop systems and select ThinkBook models. It supplies power at 20 V and 3.25 A, providing a reliable source of energy whether you are working at a primary workstation or keeping a spare unit on hand for quick swaps.
The adapter uses a slim-tip charging connector that mates cleanly with compatible Lenovo devices. A 1.8 m DC output cable gives you flexibility when arranging equipment on a desk, and the included 1 m C5 power cord reaches standard wall outlets or under-desk power strips with ease. With an average conversion efficiency above 89 percent, the adapter limits wasted energy and helps keep operating temperatures within a safe range.
Because it accepts an input range of 100 V to 240 V, the same unit can travel between offices in different countries without a voltage converter. Compliance with more than twenty-five global electrical safety standards supports dependable operation in corporate IT environments, classrooms, and home offices alike. Lenovo backs the adapter with a one-year customer-replaceable warranty, so technicians can keep downtime to a minimum.
Whether you are equipping a new fleet of small-form-factor desktops, setting up a hot-desk area that needs extra power supplies, or simply replacing a lost adapter, the Lenovo 4X21J81436 offers a straightforward, efficient solution that integrates seamlessly with supported Lenovo hardware.
