1st Gen Big Square Female to Male Laptop DC Power Adapter Connector Plug

This laptop power converter adapter features a first-generation big square female input and matching first-gen big square male output tip. It works as an extension and interface converter for laptops equipped with proprietary big square power ports, solving issues such as overly short original charging cables or mismatched cord heads.

Thickened pure copper conductive contacts inside guarantee stable continuous power delivery during long hours of office work, design rendering and video playback.

The built-in intelligent safety chip provides full circuit protection to prevent damage to the laptop battery and mainboard caused by abnormal voltage and current surges.

The tiny integrated structure takes minimal space in backpacks and desk drawers, perfectly suited for business trips, student daily use and emergency spare power conversion. No soldering, wiring modification or driver installation required, plug and play directly.

It is an affordable practical accessory that maximizes the utilization of your existing big square power adapters without buying extra brand-specific laptop chargers.
