Purpose and audience

This ABLEGRID AC adapter replaces the original mains charger for Bose Companion 2 Series II and Series III desktop speakers. It accepts AC 100-240V at 50-60Hz worldwide input and delivers DC output through a barrel tip connector. The unit is built for owners who need a direct replacement power supply for these specific speaker systems.

Build integration

The adapter plugs directly into a wall socket and feeds the speaker’s DC input jack, removing the need for the original factory brick. CE, FCC and RoHS certifications confirm compliance with common safety standards. Over-voltage and over-heat protection circuits guard the connected speakers during extended use. Buyers must verify that the barrel tip diameter and polarity match their speaker before ordering.

Sustained-load behaviour

Continuous operation is supported when the adapter is kept in a ventilated area away from heat-trapping surfaces. The protection circuits are designed to activate if internal temperatures rise or input voltage spikes, preventing damage to the speaker electronics. The unit is not intended for devices with different voltage, current or connector requirements.

Questions about this item

What input voltage range does the adapter accept for worldwide use?

It accepts AC 100-240V at 50-60Hz, so it works on mains supplies anywhere without a separate voltage selector.

How much heat protection does the unit provide during all-day operation?

Built-in over-heat protection shuts the charger down if internal temperatures rise too high, letting it run continuously when kept in a ventilated spot.

Which connector tip does the charger use to fit the speaker?

A barrel-style tip is fitted; match the DC output polarity and tip dimensions to the speaker’s power socket before plugging it in.
