Compatible Soundbar Power Supply

The unit includes a 10 ft power cord for flexible placement. It is built with new components and carries FCC, CE and RoHS certifications.

Output Capacity and Protection Limits

The adapter provides a steady 18V DC output designed for the specified soundbar models. Integrated safeguards include over current protection, over voltage protection, short circuit protection and total power protection. These features prevent damage during electrical anomalies. The supply is not suitable for devices requiring different voltage or polarity.

Smart chip circuitry manages overheating protection during normal operation. High-quality wires and isolation materials reduce interference and support stable power delivery. The adapter runs from standard mains voltage without a separate voltage selector. No active cooling fan is fitted, so silent operation is maintained.
