BASEUS 19V 40W AC Adapter for Harman Kardon Onyx Studio 8 7 6 5 4 3 2 1

Replacement 19V 40W AC Adapter

This AC adapter replaces the original power supply for Harman Kardon Onyx Studio speakers from the first generation through the eighth. It delivers 19 volts at 40 watts through a US-type plug and a 10-foot cord. The unit accepts 100 to 240 volt input at 50 to 60 hertz for worldwide use. It is a new component supplied by BASEUS.

Capacity and Headroom

The 40-watt output matches the OEM specification for continuous operation of the compatible Onyx Studio models. It provides enough headroom for normal playback volume and charging cycles. The adapter will not support speakers or devices that require higher voltage or wattage than 19V 40W. Buyers needing more power for larger systems cannot use this unit.

Build Integration

The 10-foot cable length gives flexibility for outlet placement without an extension lead. A US-type plug fits standard North American sockets directly. The cord is described as resistant to bending damage for durability. No additional converters or cables are required for the listed speaker models. Safety certifications include ETL, CE, FCC and RoHS with over-voltage, over-current and short-circuit protection.
