Product Description:

A 1st-generation big square female-to-male DC power adapter connector for laptops with compatible proprietary big square power ports.

Core Selling Points:

The dedicated female input and matching male output extend compatible big square charging cords. Thickened high-purity copper conductive contacts support stable continuous power delivery with low impedance to help reduce heat and power loss under sustained full load. An integrated safety circuit provides overvoltage, overcurrent, overheat, and short-circuit protection. The compact lightweight structure is easy to store for travel, office use, or backup, while the tight snap-fit connection helps reduce loose contact and unexpected power interruptions.
