Different Charger between iPhone and iPad
Speaking of electric chargers, why the following charger can not charge the ipad but it works with the iPhone?

Instead this one works with the iPad but does not work with the iPhone?

What differentiates an iPhone from an iPad, in terms of internal components with regard to the electric charge?
Thank you
iPhone 5, iOS 6
