Replacement AC Adapter for Sony

This 20V 3A AC adapter replaces the original Sony AC-S20RDP3A unit. It is intended for owners of compatible Sony laptops who need a direct replacement power supply. The adapter is supplied new and guaranteed to meet OEM specifications. Buyers who need a different voltage or connector type should verify compatibility before purchase.

Practical limits of the barrel connector interface

The adapter delivers a fixed 20V output at 3A through a barrel connector that must match the laptop's input exactly. Polarity, tip diameter and pin dimensions are not interchangeable across models. A 12-month warranty covers defects, with a 60-day window for free replacement or refund. Units used with an incorrect laptop model may not function or could cause damage.

The single specification that decides fit

The critical figure is the 20V 3A rating combined with the AC-S20RDP3A part number. Only laptops that list this exact part number or an identical voltage and current requirement will operate correctly. If your original adapter carries a different part number or power rating, this unit is not the correct match.
