## Questions & Answers

**Q: What’s the knob shaft dimensions for cutout**
A: diameter 6mm =0.235'', length 10mm =  0.41''

**Q: What kind of battery can you power this with?**
A: Mine has been playing continuously for an hour and ten minutes (so far) using a 3.7 volt LiPo battery.
Battery was almost fully charged (4.1 volts) and is powering this little amp and a  bluetooth receiver in a vintage tabletop radio converted into a bluetooth speaker.
I would imagine this amp could also be powered by a single 18650 li-on battery

**Q: Does it come with the knob shown in the picture**
A: Yes.  The knob is a power switch and volume control.

**Q: What is the difference between this model and the discontinued dk-amp30w model? thank you!**
A: I believe it is an upgraded design from the last board.

### ⭐⭐⭐⭐⭐ Good product!
*by T***E on 18 October 2022*

It sounds really nice and hides the frequency generated from the supplied power really will! the output of the speaker is independent of the power source which means that neither audio source nor power source need to be grounded with the same wire. would definitely recommend it!
