What problem do you need help with? All you E told anyone is that it's a charger for probably an MP3 player of some kind.
If you are looking for a repair to the charger, that's not usually possible.
If you are looking to replace the charger, what sort of connector does it need? What voltage (should be stated on the old charger) and what current rating? It's likely to be 5 Volts at a few hundred milliamps (likely written on the old power supply). If we are very lucky, the connector will be a mini- or micro -USB. If not, it'll probably be some kind of roundpin connector. The only challenge will be getting he right size and making sure the polarity is right. It's usually positive to the centre conductor (very likely marked on he old power supply), but every so often some wally designs things the other way round
