Replacement charger for Sony VGN-Z series

This 19.5V 3.96A 75W AC adapter replaces the original power supply for Sony VGN-Z21WN/B, VGN-Z21ZN/X, VGN-Z31VN/X and VGN-Z31WN/B laptops. It delivers the exact voltage and current those models require. The unit is new and covered by a 24-month warranty. Builders needing a different connector or higher wattage should look elsewhere.

Thermals and power draw in normal use

The adapter accepts AC input from 100 to 240V at 50 to 60Hz, making it suitable for worldwide mains voltages. It converts that input to a steady 19.5V DC output at up to 3.96A. No active cooling fan is present, so operation is silent. The 75W rating matches the laptop's original specification.

Included 6.5mm*4.4mm connector

A detachable power cord with a US, UK, EU or AU plug is supplied so the charger works in your region without an extra travel adapter. The DC plug measures 6.5mm by 4.4mm and fits the listed Sony models directly. The package contains the adapter and the cord only; no additional cables or software are bundled.

Questions about this item

How do I connect the 6.5mm*4.4mm connector to my Sony VGN-Z series laptop and which AC cord do I use?

Match the 6.5mm outer and 4.4mm inner diameter barrel plug to the laptop's DC jack; the package includes a US, UK, EU or AU power cord that fits your wall outlet, so select the cord that matches your country.

Will the cable or the 75W adapter brick need replacement after a couple of years of daily charging?

The 19.5V 3.96A brick and detachable mains cord are rated for continuous 100–240V 50–60Hz input; the supplier covers the unit for 24 months, after which normal wear on the cable strain reliefs or the connector tip may require a new adapter.

At what load does the 75W rating become a limit during long work sessions?

Sustained draw at the full 19.5V 3.96A (75W) output is the thermal ceiling; running the adapter continuously at that level will hit the design limit before any other constraint appears.
