It is the only one that works properly because of the voltage polarity, if you use another lead, even if it fits in the socket, you risk damaging the radio by reverse voltage. The outside contact of the 3R lead is (+) positive, center is (-) negative 5V. Most other leads are outside (-) negative and center (+) positive 5V. If you did use the correct lead then it could be a warranty claim, if using the wrong lead you've probably 'bricked' it unfortunately, and it will need repair (cost prohibitive) or replacement (probably cheaper).
