120W 19V 6.32A AC adapter

The usbroway PA-1121-28 delivers 120W at 19V 6.32A for compatible Asus gaming and mainstream laptops. It replaces the original A15-120P1A unit on models such as ROG GL502VT, N750, N550 and GL552VW series. Buyers needing a different voltage or connector should look elsewhere.

Installation and common issues

Connect the AC cable to the adapter, plug into a 100-120V 50-60Hz outlet, then attach the DC plug to the laptop. The barrel connector must match the device jack exactly; a loose fit causes intermittent charging. CE certified internal circuitry provides multiple protections against over-voltage, over-current and short circuits.

Capacity and headroom

Rated at 120W output, the adapter comfortably powers the listed Asus notebooks under full load while charging the internal battery. It runs out of headroom if the system draws more than 6.32A at 19V, such as when driving high-power external GPUs or multiple peripherals beyond the laptop's design spec.
