## 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ fit is good - works greak
*by J***A on July 26, 2021*

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 Amazon'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!

### ⭐⭐⭐⭐⭐ Charge it
*by C***S on May 26, 2024*

### ⭐⭐⭐⭐⭐ Perfect charger
*by D***S on August 17, 2022*

I needed this for my HK 4 Onyx Speaker and it’s exactly what I needed. No issues since having it! I’ve had it for quite a bit now.
