Direct replacement charger

This 19.5V 3.96A 75W AC adapter is built as a direct replacement for Sony VGN-BX41VN VGN-BX41XN VGN-BX51VN VGN-BX51XP laptops. It delivers the exact voltage and current those models require. The package includes the adapter and a matching power cord for your region. It is intended for owners of those specific Sony notebooks needing a new power supply.

Connector and input limits

The barrel connector measures 6.5mm by 4.4mm, so it only fits laptops with that exact jack size. The adapter accepts AC input from 100 to 240V at 50 to 60Hz, making it usable worldwide with the correct cord. It cannot power devices that need a different voltage, current or connector polarity. Buyers with laptops using USB-C charging or a different barrel dimension cannot use this unit.

Output specification decides fit

The single specification that decides compatibility is the DC output of 19.5V at 3.96A, which equals 75W. Your laptop must list this exact voltage and at least this current on its original charger label. If the original unit shows a different voltage or a lower current rating, this adapter will not work correctly. Always verify the label before ordering.

Questions about this item

How do I know this adapter fits my Sony VGN-BX41VN or VGN-BX51XP?

This model is listed for VGN-BX41VN, VGN-BX41XN, VGN-BX51VN and VGN-BX51XP. Match your laptop model to that list and verify the original charger shows 19.5V and 3.96A.

Will the 75W rating actually charge my laptop while I am using it?

The adapter delivers 19.5V at 3.96A for 75W total. If your Sony laptop draws up to that level under load, it will charge during use; heavier loads may only maintain battery level.

What does the 6.5mm by 4.4mm connector mean for compatibility?

The barrel plug measures 6.5mm outer diameter and 4.4mm inner diameter. Your Sony laptop must accept that exact size, otherwise the plug will not seat or make contact.
