What this adapter replaces

This WAWEIS AC adapter replaces the Liteon PA-2121-1-LF unit. It delivers 12V at 3.5A and -53.5V at 1.55A through a 4-pin connector. The 10 ft power cord gives flexible placement for laptop charging.

Installation and common issues

Plug the mains lead into any 100-240VAC 50/60Hz outlet and connect the 4-pin tip to the laptop. The unit includes over current, over voltage, short circuit and total power protection. A smart chip adds overheating protection and anti-interference isolation.

Check before ordering

Verify that the original charger carries part number PA-2121-1-LF or 341-0502-01. Confirm the laptop requires 12V 3.5A and -53.5V 1.55A on a 4-pin plug. This adapter is not for devices needing a different voltage, current or connector type.

Questions about this item

How do I confirm the adapter is delivering the 12 V 3.5 A or -53.5 V 1.55 A output after I connect it?

The unit powers on when the mains plug is inserted into a 100-240 VAC 50/60 Hz socket and the 4-pin connector seats firmly in the laptop; the built-in over-current, over-voltage, short-circuit and total-power protections engage automatically if any rail exceeds its limit.

What comes in the box and what must I source separately?

The package contains the AC/DC adapter with an integrated 10 ft power cord and the 4-pin PA-2121-1-LF output cable; no separate mains lead or DC cable is required.

Which version should I choose for a Liteon supply labelled 341-0502-01?

This single model matches the 341-0502-01 part number and the 12 V 3.5 A / -53.5 V 1.55 A ratings exactly, so no alternative version or capacity selection is needed.
