Black DC Power Adapter Converter, 4.5×3.0mm Female to 5.5×2.1mm Male for Laptops

This compact black DC converter adapter features a 4.5 × 3.0 mm female input and universal 5.5 × 2.1 mm male output.

High-conductivity internal metal contacts guarantee steady power transfer without overheating under regular load. The integrated molded structure avoids wire breakage issues compared to cable-style converters. Matte black scratch-resistant exterior resists fading and wear for long-term home, office and business travel use.

Plug-and-play without extra drivers or wiring modification, lightweight and pocket-sized for convenient storage in laptop bags, an economical multi-device power matching adapter.
