19.5V 3.96A 75W adapter for Sony VGN-CS series

This 75W AC adapter delivers 19.5V at 3.96A for compatible Sony VGN-CS21S models. It accepts 100 to 240V input at 50 to 60Hz for worldwide use. The barrel connector measures 6.5mm by 4.4mm. A region-specific power cord is included in the box.

Replaces a lost or failing original charger

Use this unit when the factory-supplied power supply is missing, damaged or no longer holds a charge. The 75W rating matches the original specification for the listed Sony notebooks. The jump is worth it when the laptop will not power on or the battery refuses to charge with the old adapter.

Verify connector size and voltage before ordering

Confirm the laptop requires exactly 19.5V DC output and a 6.5mm by 4.4mm barrel tip. Check that the existing adapter label shows 3.96A or 75W to ensure compatibility. The package includes a power cord with a US, UK, EU or AU plug suited to your region.
