Dangerous may burn or damage the devices connected to it.

The brand Belkin has had me pretty good reputation, but ultimately it is also equipment manufactured in China with all the inconvenience as possible, in this case mine lasted only a few hours before I burn a pregnant Bluetooth and doing badly heated my iPhone 5s, it is only thanks to the burning smell that I could realize before it becomes too serious that the offending was the Belkin car charger, this little joke therefore cost me over 80 euros, I have not had that buys me a new Bluetooth speaker and put in the trash charger Belkin!
Upon investigation it turns out that this car charger is not sold by Belkin in Europe, but only to Etas States and Canada, which could be explain the large number of problems on this product, in fact it seems to me as electrical standards are not the same in Europe and the States ... so safe!
