Query: Used once - nearly ruined my iPod Touch

This thing is a waste of money that may ruin the device you are trying to charge. I used the plug-in adapter portion of this one time with my iPod Touch. Fortunately I was also using the iPod while it was charging; so, I saw when the iPod came up with a warning that it was overheating and the screen shut off. I immediately unplugged it and it was several minutes before the iPod cooled off enough to come back on.When I bought it, there weren't that many negative reviews. Coming back and reading them makes me realize how fortunate I am since others have had their equipment fried by this thing. My recommendation: It's not worth the risk. Don't buy it!
