I have a 2nd gen iPod Touch and I want a wall charger for it. I also have an LG Xenon wall charger that's USB so my iPod cable will fit in it. I'm wondering if it will harm the iPod by using it? I plugged it in just to try it and it works, but I quickly unplugged it because I didn't want to harm it. The charger says the following: Input: 100-240V-50/60Hz 0.2A Output: 5.1V - 0.7A Any help would be greatly appreciated!!
