    This 10-centimeter short DC adapter cable features a first-gen big square female input and a 5.5×2.5mm male output, allowing you to use the original large square laptop power supply to power various devices with standard 5.5×2.5mm DC ports.

    High-conductivity copper conductors inside guarantee steady current output under daily charging load. The flexible insulating outer layer resists abrasion and aging for long-term indoor use. Reinforced plastic protection at the connection point prevents wire breakage caused by repeated pulling and bending.

    Plug-and-play design requires no additional setup. It serves as an economical spare conversion cord for home, office and short trips, avoiding the need to purchase extra independent power adapters.
