Review: fit is good - works greak - There are several reviews claiming that the plug that goes into the speaker is too small. It fits my Onyx Studio 3 just fine! It is NOT loose. The OEM brick adapter got short-circuited when my house got water in the lowest part of the house (darn global warming!). This was desertcart's choice and it worked out well. I, too, was leery about getting ANY non-OEM after reading many of the reviews. However, after wasting too much time trying to figure out everything I finally just ordered this one! I'm glad I did. It works for me!

## Questions & Answers

**Q: Does it charge so it can used without being connected?**

**Q: Does this come with the cable to connect to an wall outlet?**
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

**Q: This says Onyx 5 4 3 2 1 in some places but only 4 3 2 1 in others. Does it work for the 5 or not?**
A: I am unsure

### ⭐⭐⭐⭐⭐ Quality product that does exactly what it is supposed to do—put electricity in stuff.
*by A***R on September 20, 2017*

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.
