Compatible AC adapter for Onyx Studio speakers

This AC adapter replaces the original power supply for Harman Kardon Onyx Studio models 1 through 5. It delivers the required voltage and current to run the speaker or recharge its internal lithium-ion battery. The unit includes a US mains cable for direct wall connection.

Lightweight design with standard thermal profile

At 8.8 ounces the adapter is easy to carry alongside the speaker. In normal use it runs at typical wall-wart temperatures with no audible fan noise because it uses passive convection cooling. Power draw matches the speaker's factory specification.

Questions about this item

How do I connect the AC adapter to my Harman Kardon Onyx Studio speaker?

Plug the US power cable into a wall outlet then insert the barrel connector into the speaker's DC input jack; the step users often miss is seating the barrel fully until it clicks so charging actually begins

What part of this adapter will need replacement first?

The detachable US power cord and the barrel-tip cable see the most flexing; if either frays or the tip loosens, swap that cable rather than the whole brick
