This 10-centimeter short DC conversion cable is built with first-generation big square female input and 7.9×5.5mm female output. It allows you to share your original large square laptop power supply with devices that adopt standard 7.9×5.5mm DC male plugs, eliminating the need for multiple separate chargers.
Low-resistance internal wiring maintains stable current output during all-day continuous charging. Flexible scratch-resistant outer insulation resists aging and abrasion for daily indoor use. Thickened plastic reinforcement at cable joints effectively avoids wire fracture caused by frequent pulling, twisting and bending.
Plug-and-play without extra installation or modification. Lightweight small size is easy to store in backpacks for home, office and short trip backup, a cost-effective power matching accessory for multi-laptop users.
