19V 135W output for laptop charging

This Lite-On PA-1131-07 adapter delivers a 19V 7.1A output rated at 135W. It accepts a universal 100-240V input at 2.15A across 50-60Hz mains. A 7.4 x 5.0 mm male barrel connector without a central pin mates with the device. A detachable power cord is included in the box.

Fits laptops needing 19V 135W with 7.4 x 5.0 mm plug

The unit suits owners of laptops that specify a 19V 135W supply and use the 7.4 x 5.0 mm barrel without a centre pin. Buyers whose machines require a different voltage, a higher wattage, or a connector with a central pin should look at something else. The fixed output also means it cannot serve variable-voltage USB-C devices.

Connector is 7.4 x 5.0 mm male barrel without

The single specification that decides compatibility is the 7.4 x 5.0 mm male barrel connector lacking a central pin. Only devices designed for this exact plug geometry will connect securely and receive the correct 19V 7.1A supply. Verify the laptop jack before ordering.

Questions about this item

How do I install the Lite-On PA-1131-07 and which step is often missed?

Connect the 7.4 x 5.0 mm male plug without a central pin firmly into the laptop's DC jack, then plug the IEC C13 power cord into the adapter and a 100-240V~ 50-60Hz wall outlet; the step people miss is seating the barrel connector fully so the 19V 7.1A output engages.

What maintenance or replacement will the PA-1131-07 need over time?

The detachable power cord can wear at the strain relief and should be replaced if the insulation cracks; the adapter itself has no user-serviceable parts, so once the internal protection against incorrect voltage, short circuit or overheating triggers permanently the whole 135W unit is replaced.

What limit appears first when the PA-1131-07 runs under sustained 135W load?

Internal overheating protection activates first, shutting off the 19V 7.1A output until the unit cools; this safeguard operates within the 100-240V~ 2.15A 50-60Hz input range and resets automatically once temperature drops.
