WAWEIS 19V AC/DC Adapter for Harman Kardon Onyx Studio 2 II White laptop battery

SKU CH-GTA7-WM5MM

A 19 V AC/DC adapter with 10 ft cord and safety protections replaces the power supply for Harman Kardon Onyx Studio 2 II White speaker

  • World-wide 100-240 V input works in any country
  • 10 ft total cord length gives flexible placement
  • Over-current, over-voltage and short-circuit protection safeguards the speaker
  • FCC, CE and RoHS certifications confirm safety compliance
  • 12-month warranty backs the new replacement adapter

Compatible Power Adapter

This 19V AC/DC adapter replaces the original supply for the Harman Kardon Onyx Studio 2 II White Bluetooth wireless speaker. It accepts worldwide input voltage from 100 to 240VAC at 50 or 60Hz. The unit carries FCC, CE and RoHS certifications for safety compliance. Total power cord length measures 10 feet for flexible placement.

Build Integration

The adapter plugs directly into the speaker's DC input jack without additional cables or converters. Its 10 foot cord frees the speaker from tight wall outlets and allows positioning on shelves or tables farther from the socket. Built-in over current, over voltage, short circuit and total power protection safeguards the connected device. Smart chip circuitry adds overheating and anti-interference defence during operation.

Upgrade Context

This unit replaces a lost, damaged or worn-out factory charger for the Onyx Studio 2 II White model. The jump is worth it when the original supply fails or when a spare is needed for travel or a second location. Buyers who need a charger for a different speaker model or a higher voltage device cannot use this adapter. It is not a battery and does not add portable power to the speaker.

Questions about this item

Will the 19 V output handle continuous speaker playback without overheating?

The adapter includes overheating protection with a smart chip and short-circuit protection, so it is designed to run safely during extended use at 19 V.

How much fan noise or heat does the adapter produce when powering the speaker all day?

The unit has no fan; it relies on passive cooling and built-in overheating protection, so it stays silent and only warm during all-day operation.

Does the package include the AC mains cable, or do I need to supply my own?

The adapter comes with a total 10 ft power cord that includes both the AC and DC sections, so no separate mains cable is required.
