iPad 10W Power Adapter - Safe To Use On iPhone and iTouch?

The iPad charger won't fry your iPhone or iPod Touch for that matter, there's resistors built in to limit the amount of current to protect it from spikes, hope this helps.
Current isn't "pushed" by the charger, it's "pulled" by the device so the device itself is the limiting factor. The current rating of the charger is simply how much it is able to supply based on the demand of the device.
There are no magic resistors in play here. A resistor adjusts voltage not current btw.
On the contrary...when it say that it is still charging a little tiny bit.
I am so glad they kept the same adapter. I am on a life fitness machine in a hotel right now...and although it said it was NOT compatible...and not charging...it is giving a small charge which is better than using up my charge for the day.
Iteresting that on the status bar it says not charging...but if I got to a battery monitor, it says that it is.
All these devices have lithium ion batteries. Lion batteries need smart charge controllers or they will melt or even worse, can explode. So they have a microprocessor, albeit a rather stupid one, that controls the whole process. It regulates the amount of current the unit will draw for it's charge. So, bottom line, yes it is perfectly safe to use, since the charge rate is determined by the unit's charge controller and it will only draw up to it's programmed limit regardless of what is available.
On a personal note, my 3GS will charge about 30% faster with the 10 watt unit. I also can charge my Sony and Sennheuser headsets with it as well as my Garmin 705.

iPad 10W Charger can be used on most of the iHandheld stuff
To end our confusion and your headache, NO using the iPad charger will not harm your iPhone, iPod, or iTouch, or any hand held iThing. The 10W charger merely indicates that 10W are available for use if needed.

My understanding is the Charger is intelligent and it can switch between 0.5, 1 and 2.1 amps on the fly according to whats plugged it. Its designed to be able to charge and Ipad at maximum efficiency yet be able to charger an Iphone without smoking it.

Update: My experience using iPad charge and iPhone 3G
Just bringing back an older thread rather than start a new one. . .
I used the iPad charger on my iPhone 3G twice now, and both times had the following results:
1. The charge icon did come on. But . . .
2. The charge indicator did not move at all during charging, and no indication it was fully charged. When disconnected, the phone did not show as any change in charge.
3. Turning the phone off and back on showed that the phone was completely charged.
I reproduced this effect twice. Anyway, just to be safe I am going back to using my iPhone charger with my iPhone, etc. I know the IFUs say they you can use the iPad charger with the phone, but just a little nervous that the phone will not know when to quit!

I've used the 10W iPad charger to charge all kinds of devices that have a USB connection -- iPhone 3GS, iPod Touch, DSi, DSi XL, AA batteries, to name a few.
