I have a USB travel Charger for iPod mp3 players. I have an iPod nano chromatic and the charger said that it is compatible with all ipods and mp3 players. But now when i plugged it in i am not seeing the symbol on the battery icon that my iPod is charging. what is the problem?
You need to split this problem into smaller parts to find the answer. Does your USB charger work with another item? Will your iPod charge from another charger? My charger has 3 components: the mains lead, the charger box and the USB lead. I can check the mains lead on another device and I can plug the USB lead into my laptop to charge my iPod. These are ways to help find which bit has gone wrong. If you put the charger close to your ear while it's working you should hear a faint hum.
