Can I use a 9v battery to power usb speakers? Answered
I recently made a mini amplifier out of some usb speakers and at the moment it's powered by usb but I want to make it battery powered so do you think a 9v battery will be fine? I don't want to ruin the amp so I want to make sure but it has a 16v 470uf capacitor on it and that's about all I can tell you about the circuit board. I'd imagine it would be fine but is there any way to tell?
