Compatible Sony Models

This 75W AC adapter is built for Sony PCG-737, PCG-741, PCG-745, PCG-747 and PCG-748 laptops. It supplies 19.5V at 3.96A to match the original charger specification. Buyers needing a different voltage or a higher wattage unit should look elsewhere.

Input Range and Thermal Behaviour

The adapter accepts 100 to 240V AC at 50 to 60Hz for worldwide mains compatibility. At 75W output the brick runs warm but stays within normal limits for a compact supply. No active cooling is present so silent operation is standard.

Barrel Connector and Included Cord

A 6.5mm by 4.4mm barrel plug fits the listed Sony models directly. The package includes a region-specific power cord with US, UK, EU or AU pins. Users with a different barrel size or a proprietary docking connector cannot use this unit.

Questions about this item

How do I connect the 6.5mm*4.4mm barrel plug to my Sony PCG-747 without bending the centre pin?

Align the 6.5 mm outer barrel and 4.4 mm inner pin straight on, push in until it seats fully, then route the cable so the connector is not levered sideways — side load is what bends the pin.

Which part of this 75 W adapter will wear out first and need replacing?

The detachable mains lead and the DC cable near the barrel plug see the most flexing; the adapter body itself has no user-serviceable parts and is rated for 24 months.

At what point does the 19.5 V 3.96 A output hit its thermal limit during continuous load?

The unit is designed to deliver the full 75 W continuously within the 100–240 V 50–60 Hz input range; the internal protection engages if the case temperature exceeds its design threshold.
