240W DC 7.9×5.5mm Male to 5.5×2.5mm Female Power Adapter Plug, Compatible with IBM Laptops

This high-power DC conversion plug realizes quick interface switching between IBM dedicated 7.9 × 5.5 mm male power tips and standard 5.5 × 2.5 mm female DC ports, rated up to 240W to meet power demand of high-spec IBM gaming and workstation laptops. High-purity copper conductive terminals inside greatly reduce power loss during long-hour continuous operation, avoiding unstable charging, automatic throttling or unexpected shutdown caused by poor contact. Integrated intelligent safety chip delivers full circuit protection to safeguard laptop battery and motherboard from abnormal current and voltage risks. Ultra-small integrated structure takes negligible space in backpacks and storage bags, convenient for mobile office and spare backup use.

No wiring modification or driver installation required, simply plug your 5.5 × 2.5 mm charger into the female port and connect the male tip to your IBM notebook to power on instantly. It is a cost-effective conversion accessory that allows reuse of common 5.5 × 2.5 mm power adapters instead of purchasing exclusive IBM 7.9 × 5.5 mm chargers separately.
