IPad vs. IPhone car charger?

No idea but probably not.

The iPhone uses a 5 volt .5 amp charger. The iPad uses a 5 volt 1.2 amp charger. The iPhone charger will work, but it will not charge and allow you to use the device at the same time. It would work like a trickle charger on your car. It will get there, but it's going to take a lot longer.

Jim, where did yu get your values:

The Apple chargger that cam with my iPone 4S say 1 amp. The charger that cam with my iPad 1 was 2 amps and the APple store also says the iPad charger is 2 amps (10 watts)

I stand corrected, it's early here and I just had coffee. I will shut up now and go away.

"The iPhone uses a 5 volt .5 amp charger. The iPad uses a 5 volt 1.2 amp charger. "

In addition to what lllaass posted, we know nothing of the charger the OP is using?

If the car charger you are using indicates that it is on,y for the iPhone it most likely does not provide enough power to charge your iPad efficiently. There are car chargers that specifically indicate they will charge an iPad. I have one from Griffin that works very well.

Why Apple is not making chargers that specifically say it's for iPad or iPhone.

I saw these kind of questions a lot online.

Some say using an iPad charger for iPhone will damage your iPhone, or vice versa.

Some say you can use both interchangeably, just it will charge slowly on your iPad, or make your iPhone extremely hot.

The Apple chargers do specify that they are for iPhone and iPad. They do not even look the same. Apple does not make chargers for the automobile, only 3rd party developers do.

Apple says that you can use both the iPad or the iPhone charger for both the iPad and the iPhone. Based on the device and the charger combination, the devices will just charge at different rates.

My iPhone gets really hot when I use the iPad charger on it. Doesn't seem like a good idea unless there is a problem with my iPhone causing this.
