Mini usb power port needs replaced on my blue tooth speaker

new speaker would probably be best. no idea what speaker you have, but they’re pretty much all held together with copious amounts of glue and not really designed to be taken apart and then reassembled. If you have one that can be taken apart with relative ease then you would need to find an exact match port, or one very close to exact, and then desolder and then resolder the new connector.
