Compatible Sony models

This 75W AC adapter powers Sony VGN-SZ390, VGN-SZ3VWP/X, VGN-SZ3XWP/C and VGN-SZ4 laptops. It delivers a steady 19.5V at 3.96A to match the original supply. The unit accepts worldwide mains voltage from 100 to 240V at 50 to 60Hz. A detachable power cord with the correct regional plug is included in the box.

Ideal replacement or spare

Owners of the listed Sony notebooks who need a new or backup charger will find the correct voltage and connector here. Users whose laptops require a different DC tip size or a higher wattage rating should look for another model. Travellers needing only the adapter brick without a cord must source that separately.

Connector fit check

The barrel plug measures 6.5mm outer diameter by 4.4mm inner diameter and carries centre-positive polarity. Verify that your Sony laptop uses this exact tip before ordering. A mismatched connector will prevent charging even when the voltage and current ratings appear correct.
