The Lenovo GX21F23046 power adapter is a compact black adapter designed for both indoor and outdoor use. It accepts a wide input voltage range of 100–240V and is supplied with both AC and DC cables, allowing flexible connection options. The adapter's housing measures approximately 200×100 mm and the package includes a short 0.18 m cable; the unit weighs 1 kg. This adapter is intended to provide reliable power to compatible portable devices and laptops that require a small, versatile external power source.

Advantages

The adapter's wide input voltage range (100–240V) enables use in multiple regions without a voltage converter. Inclusion of both AC and DC cables provides immediate compatibility with different equipment and installation scenarios. The compact footprint (200×100 mm) and black finish simplify integration into workspace or mobile setups. The short 0.18 m cable reduces excess slack where a close connection is needed, and the 1 kg weight indicates a robust build suitable for repeated handling.
