Replacement AC Adapter for Bose Solo 5

This replacement AC adapter is built for the Bose Solo 5 TV sound bar system (418775) and the Bose Companion 20 computer speakers (329509-1300). It restores power to these specific audio devices when the original supply is lost or damaged. The unit is a direct-fit switching power supply with a wall plug cord.

Output Rating 18.5V 3.5A

The adapter delivers a fixed output of 18.5V at 3.5A. This exact voltage and current rating is the single specification that determines compatibility; the connected Bose system must require 18.5V 3.5A input. The wide 100-240V 50/60Hz input range allows use on mains supplies worldwide.

Certified Replacement with OEM-Match Performance

Manufacturer testing confirms CE, FCC and RoHS compliance and states the adapter meets or exceeds OEM specifications. It comfortably handles continuous operation for the Solo 5 sound bar or Companion 20 speakers. It runs out if the connected device demands a different voltage, higher current or a non-standard connector.

Questions about this item

What does the 18.5V 3.5A output mean for my Bose speaker?

It delivers the exact voltage and current the Bose Solo 5 (418775) and Companion 20 (329509-1300) require, so the speaker powers on and runs at full volume without instability.

How does the 100-240V 50/60Hz input affect where I can use it?

The wide-range input lets you plug the adapter into any mains supply from 100 V to 240 V at 50 Hz or 60 Hz, so it works worldwide with only a plug adapter.

Will this adapter physically fit my Bose Solo 5 or Companion 20?

Yes — it is built as a direct replacement for part numbers 732522-1110 and 418775, matching the original connector and polarity for both speaker systems.
