19V for Harman Kardon Charger for Harman Kardon Onyx Studio 7 6 5 4 3 2 1 Wireless Portable Stereo Speaker, AC Adapter Power Cord Supply Fits for Harman Kardon Onyx Studio, UL Listed

Bought this to replace my original Harman Kardon onyx studio 6 charger that fell down while plugged in and stopped working.This new replacement fits perfect and is working very well so far. No complaints. If they ever come up, I'll update this review.

So far so good ! It works very well for charging my Harmon Kardon Bluetooth Speaker

The type c connector came out after a year so now I have to buy another one. I use my laptop in bed so I’m not the gentlest with my laptop though. If you keep it on a desk you’ll be fine. But if you’re like me and use your laptop all over the house, be careful because it just ripped out of the socket.

iT WORKS GREAT.

Needed it. Charged it. Saved the day.

I have a Harman Kardon Onyx 5 which I haven't been able to use due to my wife losing the charger.The charger that I received seems to be built of good quality materials.The charge time of the onyx 5 using the oem charger vs the generic option is very similar and does not show signs of overheating or shorts.I like that it kinda looks like the orignal charger and the cord is long enough to have it plugged to wall and having the speaker playing anywhere in the room.
