I just fixed mine with a phillips screwdriver and an old usb cable. The port is completely gone. Unscrew the circuit panel from the back of speaker unplug the battery from the board. Strip a small section of each wire (one red-, one black+). Find an old but good charger cable for a phone cut the end off that goes to the phone and throw it away. Find your + wire (usually red) strip it back about ¼" then find - wire(usually black) and do the same. Then splice + to + and - to -. Tape it up good so cant short out and plug that usb end into the charger box u use for ur phone and you will have a working speaker Soon.
