Compatible Replacement Adapter

The WAWEIS 18V AC/DC adapter serves as a direct replacement power supply for the Altec Lansing RockBox XL IMW999 portable speaker. It delivers the required 18 volts output to charge the internal battery and run the unit from mains electricity. The unit accepts a wide 100-240VAC input range, making it suitable for worldwide travel use.

Safety Protections and Cooling

Built-in safeguards include over-current, over-voltage, short-circuit and total-power protection circuits that disconnect the output during fault conditions. A smart-chip thermal guard monitors temperature and shuts down the adapter if overheating occurs. The design uses high-quality wires and isolation materials to suppress interference and maintain stable operation without audible noise.

Ten-Foot Cord and Certifications

A single 10-foot power cord is permanently attached, giving ample reach between the wall outlet and the speaker without requiring an extension lead. The adapter carries FCC, CE and RoHS certifications, confirming compliance with electromagnetic-compatibility and hazardous-substance regulations. No additional cables, mounting hardware or software are included in the package.

Questions about this item

How do I install the 18V adapter for my RockBox XL IMW999, and what step do people often miss?

Plug the AC cord into a 100-240VAC 50/60Hz outlet, connect the DC plug to the speaker's power port, and ensure the connector seats fully; the 10 ft cord length helps reach distant sockets.

What maintenance or replacement will this 18V power supply need over time?

The unit has no user-serviceable parts; its over-current, over-voltage, short-circuit and overheating protections are built-in. Replace the adapter only if the output fails or the cable shows damage.

What is the first limit I will hit when running the Altec Lansing speaker continuously on this charger?

The adapter delivers a fixed 18V output with integrated total power protection; sustained high-volume playback will trigger the over-current or thermal safeguards before any other limit.
