  • Delivers stable 9 V 0.3 A output for compatible Sony devices
  • 5 W rating keeps power draw low and efficient
  • Built-in safeguards protect against incorrect voltage and short circuits
  • 5 mm barrel connector fits matching equipment without adapters
  • Designed for 120 V 60 Hz mains supply in supported regions

Purpose and audience

This genuine Sony AC-T90S power adapter supplies 9 V at 0.3 A for small electronics that require a 4.5 W source. It accepts a 120 V 60 Hz mains input and terminates in a 5.5 mm barrel connector for direct device connection.

Suitability and limits

The unit suits owners of legacy Sony gear or compatible equipment that specifies exactly 9 V 0.3 A via a 5.5 mm barrel jack. Buyers whose hardware demands higher current, a different voltage or an alternative connector type should look elsewhere.

Deciding specification

The fixed 9 V 0.3 A output rating is the single figure that determines whether this adapter will power the intended device safely. Verify the target equipment lists the same voltage, current and barrel size before purchasing.

Questions about this item

Will this adapter power my device that needs 9 V and 0.3 A via a 5.5 mm barrel plug?

The AC-T90S delivers exactly 9 V at 0.3 A through its 5.5 mm barrel connector, matching those requirements.

Can I use this 120 V 60 Hz adapter in regions with a different mains voltage?

The adapter is rated for 120 V 60 Hz input only; it cannot be plugged directly into other mains voltages.

How do I confirm the adapter is supplying the correct 9 V 0.3 A output after connecting it?

Measure the barrel-plug voltage with a multimeter; it should read close to 9 V under load.
