Key Features

• Power Specs: The 19V 38W output supports faster charging than many small adapters and is matched to the Onyx Studio family for consistent performance.

Who It's For

This adapter is best for Harman Kardon Onyx Studio owners who need a direct replacement power supply that matches the speaker's original 19V input and offers a longer cord for flexible placement. It suits home users who want a safe, well-protected charger and travelers who prefer a compact, portable adapter.

Users who should look elsewhere include buyers who require an adapter with a different voltage, a country-specific plug type other than the US plug, or those who need manufacturer-branded accessories for warranty reasons. Also verify physical fit if your speaker's barrel connector or housing has nonstandard clearance, since some customers reported an imperfect fit in a few cases.
