Query: Does not charge as advertised

I am currently deployed and wanted something small to play in my office. I needed something that would both play and charge my IPOD. When I turn on the device my IPOD gives a message stating that it does not support this accessory and it will not charge my IPOD Nano 4th generation 8GB. Even though it advertises that it does charge it does not. I called the store and the representative was courteous and helpful. He even sent out a new device but it still did not charge. I have to return it for a refund.
