Can I charge my iPhone with the Apple iPad 10W USB power adapter?
Yes. The iPad charger is a high-power version of the iPhone charger, however it's completely safe to use with the iPhone.
The iPhone will only take as much power as it needs and will not be overloaded. The iPad 10W USB power adapter will charge the iPhone or iPad batteries correctly and efficiently.
