Hello, my name is Kate and I need help. I have problem charging iPod Touch 3rd gen wiith Philips USB Battery Power Pack 5200mAh. Philips USB Battery Power Pack has USB output 5v - 1A. I know that USB computer has output 0.5A The problem is that iPod Touch stops charging after 2 minutes with Philips USB Battery Power Pack. The indicator says charging so Philips work but not long, only 2 minutes. Philips has overload protector and the package say it could charging iPhone, iPod. However this is not happening when I plugged in iPod Touch to USB computer. It charges until full. No problem with USB computer I'm using original USB cable from iPod Touch on both Why the charging could be different?
