Hello from Japan. I got JBL Charge 3 for my Zynthian. It’s a Bluetooth speaker with line input and USB socket to recharge phones and tablets, but seems it is powerful enough to power our beloved gadget. Now I can take this thing anywhere to enjoy playing some nice music.

And how long lasts the power?

at least more than 3 hours.
I have been experiencing low freq noise which resembles something that comes from switching regulator or perhaps inverter circuit from the audio output ever since I started using charge 3 to power it. It does not occur when I use other 5v power sources. I think I may need to find some ways to suppress the noise since I probably could filter the noise to some extent but not confident about removing it completely.
Regards,
Tomoyuki
