Lenovo Slim 300W AC Adapter (UL)

The Lenovo GX21F23045 is a 300 watt AC adapter with a slim profile designed for Legion 5, Legion 5 Pro, and Legion 7 laptops that use Lenovo’s rectangular slim tip power port. It supplies enough current for gaming, content creation, or everyday work, so your system can run at full speed even when the battery is nearly empty.

An input range of 100 to 240 volts at 50 or 60 hertz lets you plug in almost anywhere in the world. Whether you move between offices, travel abroad, or simply want a single charger that works on any outlet in the house, this adapter handles the change without a voltage converter.

The 1.8 meter power cord reaches comfortably from a wall or floor socket to your desk, and the three-prong plug stays secure in standard outlets. The rectangular slim tip connector lines up quickly, saving you from fumbling when you need to dock and go.

Gamers and professionals who push Legion laptops with high frame rate titles, 3D rendering, or large media exports will notice fewer slowdowns because the 4.5 amp output matches the power draw these systems require. Keep one adapter in your backpack and another on the desk to avoid constantly unplugging and repacking.

Safety approvals from CE, UL, TUV, BIS, and additional agencies verify that the adapter meets international standards for electrical and thermal protection. It operates reliably in temperatures from 0 to 40 degrees Celsius and in up to 80 percent relative humidity, making it suitable for most indoor settings.
