19.5 V 120 W AC charger for Asus ROG laptops

This new 19.5 V 6.32 A adapter delivers 120 W of power for compatible Asus ROG and N-series laptops. It accepts 100-120 V input at 50-60 Hz and uses a 5.5 mm by 2.5 mm barrel connector. The unit replaces part numbers such as PA-1121-28 and A15-120P1A.

Steady 120 W output under continuous load

Internal smart circuitry provides multiple protection layers against over-voltage, over-current and short-circuit conditions. Industry-grade components keep temperatures stable while the battery reaches full capacity.

Verify connector size and voltage before ordering

Confirm that your laptop requires 19.5 V DC and draws up to 6.32 A through a 5.5 mm outer diameter and 2.5 mm inner diameter barrel jack. Check the original part number against the compatibility list including ADP-120ZB BB and PA-1121-04. This adapter is not suitable for devices needing a different voltage, current rating or connector geometry.

Yes, the connector matches the 5.5 mm outer and 2.5 mm inner diameter used by the listed Asus models.

Will this 19.5 V charger work safely with an older Asus ROG G1 or G2 that originally used a 120W brick?

The adapter is listed as compatible with the G1, G2 and other legacy ROG units that require 19 V at 6.32 A.
