120W 19V Replacement Charger

This 120W AC adapter delivers 19V at 6.32A through a 5.5 x 2.5mm yellow tip connector. It replaces lost or damaged original chargers for a wide range of Asus laptops including ROG GL551, GL552, GL752 and N550 series models. The unit accepts 100-240V input for worldwide use.

Upgrades From Lower Wattage Adapters

Owners using a 90W or lower power supply on compatible 120W-rated notebooks will regain full charging speed and prevent battery drain under heavy load. The jump is worth it when the original adapter failed or when a lower-rated substitute cannot sustain performance during gaming or rendering.

Limits Of The 5.5 x 2.5mm Barrel Interface

The round 5.5mm by 2.5mm connector fits many Asus models but is not universal across all brands or newer USB-C charging laptops. Polarity and pin dimensions must match the original exactly; the yellow tip colour helps visual identification but does not guarantee electrical compatibility. Buyers who need USB-C Power Delivery or a different barrel size cannot use this adapter.

Questions about this item

Will the 5.5 x 2.5 mm yellow round tip fit my Asus ROG GL552VW charging port?

Yes, the connector is a 5.5 mm outer diameter by 2.5 mm inner diameter yellow round tip that matches the original Asus PA-1121-28 and A15-120P1A adapters used on the GL552VW.

What is the correct way to connect this 120 W adapter so the laptop recognises it?

Plug the AC cord into a 100-240 V mains socket first, then insert the 5.5 x 2.5 mm tip firmly into the laptop’s DC jack until it seats; the laptop will not negotiate power if the tip is only partially inserted.

How often should I replace the detachable AC power cord on this 19 V 6.32 A charger?

Inspect the IEC C7 figure-8 cord whenever you pack the adapter; replace it if the insulation is cracked, the pins are bent, or the cord becomes intermittent — typically every few years with daily mobile use.
