Review: Works well - 👍😁
Review: Quality product that does exactly what it is supposed to do—put electricity in stuff. - It plugs in the wall and then into my Harman/Kardon Onyx speaker. Don't really know what else to say... but it works. I expected a quality charger that charges my speaker. And it does exactly that. I have been using it for 3 months now. It's plugged in 98% of the time and still no issues.

A: Yes wall plug is included

**Q: Could you please tell me about the Connector Size?**
A: I think connector is 5.5 mm in diameter

A: I am unsure
