Replacement Power Supply for Sony VGN-SZ4

This 75W AC adapter supplies 19.5V at 3.96A for Sony VGN-SZ4 series laptops including the VGN-SZ430N/B, VGN-SZ440N23, VGN-SZ450N/C and VGN-SZ460N/C models. It is a new replacement unit for owners whose original charger has failed or been lost. The package includes the adapter and a mains cord suited to the destination region.

Output Capacity and Headroom

The adapter delivers a continuous 75W through a 6.5mm by 4.4mm barrel connector, matching the voltage and current the notebook expects. It will run the system and charge the battery simultaneously under normal workloads. Demands that exceed 75W, such as heavy discrete graphics loads combined with fast charging, may trigger the unit's protection or cause the battery to drain slowly.

Input Range and Connector Limits

The unit accepts AC input from 100V to 240V at 50Hz to 60Hz, making it compatible with mains supplies worldwide when paired with the appropriate cord. The fixed 6.5mm by 4.4mm DC plug fits only laptops designed for that specific barrel size and polarity. It cannot be used with devices requiring a different connector diameter, pin arrangement or voltage level.
