I got a Griffin Wall Charger for my Ipod. My grandma wanted me to charge up her friend grandson's iPod . The problem is I wanted to know is after I was done charging it the light was flickering red and green at the same time. Is that suppose to do that?

It has never done that to me.

You probably had it plugged in upside down. I did this with my iPhone, and it charged, but it kept showing that it was charging, then not. Maybe it never was really charging at all! Anyway, this is my only complaint with this product, no marking to show which side is up. Always have to look before I plug in. I guess I'll scratch the Griffin logo off one side.

Now I go to charge my iPod, my iPod charges. But the light remains red.

What is wrong with it now?
