Lenovo 4X21L18243 – ThinkCentre 300W AC Adapter Gen 2 (Slim Tip)

Overview :

The Lenovo 4X21L18243 is a ultra-high-capacity 300W AC power adapter designed for the most power-demanding desktop and workstation environments. As a Gen 2 power solution, it is specifically optimized for Lenovo ThinkStation P-series workstations (such as the P360 Ultra) and high-performance ThinkCentre Tiny systems that require substantial energy for heavy computational and graphical workloads.

Equipped with Lenovo’s signature “Slim Tip” rectangular connector, this adapter provides a robust and secure power interface that prevents accidental disconnections. Despite its massive 300W output, the design maintains an efficient profile to ensure it doesn’t overly clutter specialized enterprise workstations. It is highly energy-efficient and built to maintain stable voltage delivery during sustained peak performance.

The adapter kit comes complete with a high-durability 1.8-meter line cord, making it ready for immediate deployment in data centers, engineering labs, or professional design studios. It is intended strictly for devices that support a 300W input and should not be used with lower-wattage systems unless specifically listed in the compatibility documentation.

Key Features :

• 300W power output supports elite-tier workstations and high-end Tiny PCs

• Rectangular Slim Tip interface ensures a stable and long-lasting connection

• Highly energy-efficient Gen 2 architecture minimizes heat dissipation

• Integrated protection against over-voltage, short-circuits, and overheating

• Professional-grade 1.8-meter DC and AC cables for flexible installation
