Very handy to have provided self "in case" this small device can make us good service, I tested it on my ipod, my GPS Recommended, my blackberry mobile phone and MP3 player on my son, everything was perfectly suited, not only works against by on Sony Ericsson Z710i so it is necessary to check well if yours is compatible ..... It seems that recent models should not encounter this problem.
The cell phone always falls out of power when it is needed, then camping or hiking it may be very useful. Universal charger function also very convenient. His only real fault for my taste still remaining its price but it is only an opinion.
