Building a little speaker set up for travel and have a solar powered 15000 mah battery pack that accepts usb to run power to . Any class d amps have a provision or are they all pretty much 2.1-2.5mm power jacks?
I recently built a bluetooth speaker with this Sanwu board: Stereo Bluetooth Amplifier Board Lithium Battery Powered AMP for Speaker | eBay
Tested it with usb power and it works. But I have to warn you, i makes a loud and annoying beep when turned on. Currently I'm powering it with one single 18650 lithium battery. Haven't tested the charging feature yet.
I think your speaker will run for days with that battery! 😀 Might wanna think about smaller pack if you wan't to save space and weight.
