Query: Apple I-Pod Users Beware!!!!

Apple I-Pod users beware. This product will NOT charge Apple products (I've tried both the Touch and the Classic). This is a huge ripoff. Yes--the unit works. The lights come on when you plug it into the wall, and I could charge my mobile phone with it. But nothing happens when you plug in an Apple product. Zilch! Given the number of people who use Apple MP3 players, the seller should warn everyone that it will not work on Apple products. I want my money back!
