Laptop power adapter 90W
This 90W AC adapter delivers 19V at 4.74A for compatible laptops. It accepts 100-240V 50-60Hz input and includes a 5.5x2.5mm barrel connector. CE certification is provided. The package contains the adapter and a power cord.
Replaces Liteon PA-1900-36 and PA-1900-04
Directly substitutes Liteon part numbers PA-1900-36, PA-1900-04 and PA-1900-24. The upgrade is worthwhile when the original charger fails or is lost. It is not for devices requiring a different voltage, current or connector size.
Simple plug-and-play installation
Connect the barrel plug to the laptop and the power cord to a wall outlet. The universal input handles 100-240V automatically. Common issues arise only if the tip polarity or dimensions do not match the laptop's power jack.

Questions about this item
Does the 5.5x2.5 mm barrel plug fit my laptop's charging port?
The adapter uses a 5.5 mm outer diameter and 2.5 mm inner diameter barrel connector. Measure your laptop's port or check its service manual to confirm this exact size before ordering.
What is the correct order to connect the EU, US, UK or AU power cord and the adapter to the wall outlet?
First attach the detachable power cord to the adapter's IEC C6 inlet, then plug the cord into the 100-240 V 50-60 Hz wall outlet, and finally connect the 5.5x2.5 mm barrel tip to the laptop.
When should I replace the power cord or the adapter itself?
Replace the power cord if the insulation cracks, the plug pins bend, or the IEC C6 connector feels loose. Replace the adapter if output voltage drops under load, the casing overheats, or the barrel tip becomes intermittent.
