  • World-wide 100-240 V input works in any region

19V replacement adapter for Harman Kardon Onyx

This 19V AC adapter replaces the original power supply for Harman Kardon Onyx Studio I, II and III wireless speakers. It accepts a worldwide input of 100-240VAC at 50/60Hz and delivers the voltage the speakers require. The unit is sold new and carries FCC, CE and RoHS certifications.

Practical limits of the 19V barrel interface

The adapter provides a fixed 19V output through a barrel connector sized for the Onyx Studio range. It cannot power devices that need a different voltage, a higher current rating or a USB-C Power Delivery handshake. The 10 ft total cord length sets the maximum reach from a wall socket to the speaker.

Safety protections decide suitability

Over-current, over-voltage, short-circuit and total-power protection circuits are built in, alongside over-heating and over-charge/discharge safeguards. Buyers whose speaker shows no signs of life from the original supply can use this unit; buyers who need a battery pack, a multi-voltage travel charger or a USB-C source cannot.
