SKU CH-7B65-1GT24

A 19V replacement power supply with 10 ft cord, 100-240V input, and FCC, CE, RoHS certifications

  • World-wide 100–240 V input works in any region
  • 10 ft power cord gives flexible placement options
  • FCC CE RoHS certified for verified safety compliance
  • Over-current over-voltage and short-circuit protection safeguards the speaker

Compatible replacement adapter

This 19V AC adapter replaces the original NSA40ED-190200 supply for the Harman Kardon Onyx Studio 2 wireless speaker. It delivers the same voltage and connector fit so the speaker charges and runs exactly as designed.

When the original unit fails

Swap to this adapter when the factory brick is lost, damaged or no longer holds a stable charge. The 10 ft total cord length gives extra reach compared with shorter OEM cables, making placement easier on shelves or side tables.

Simple plug-and-play install

Connect the DC plug to the speaker and the AC plug to any 100-240VAC 50/60Hz outlet; no drivers or configuration are required. Built-in over-current, over-voltage, short-circuit and over-temperature protections guard both the adapter and the speaker during everyday use.

Questions about this item

What length mains lead does the 19 V adapter ship with?

The unit includes a 10 ft power cord that covers the wall-to-adapter distance.

How do you connect the 19 V adapter to the Onyx Studio 2 without damaging the speaker?

Plug the barrel connector firmly into the speaker's DC socket first, then connect the 100-240 VAC mains plug; reversing the order can stress the port.

Which protection circuits inside the 19 V adapter will eventually wear out and need a replacement unit?

Over-current, over-voltage, short-circuit and thermal protection are built into the adapter; after prolonged use these internal safeguards can degrade, requiring a new adapter.
