Replacement AC Adapter Speaker Power Supply compatible with Harman Kardon Onyx Studio 5 manufactured and sold exclusively by Power4Laptops. Unlike many of the cheaper Power Supplies. our Power Supplies have overvoltage and overcurrent protection circuits built in. this means if you get a power surge a circuit in the Power Supply will blow before it damages your Speaker. Power4Laptops Power Supplies have also had Electrical Safety Assessment Tests conducted on them in the UK and have a valid CE Certificate which authorises them for safe use in the EU.
