A1003 charger to charge an iPhone 4S?

I've got an A1003 (12 watt, firewire 400) charger can it be used to safely charge an iPhone 4S? Any risks to the iPhone by using this charger?

Don't use it.


The A1003 supplies 12 V and the iPhone requires 5 V. The iPhone's input voltage regulator may or may not be sufficiently rated for it.
