I travel a lot and don't like to carry duplicate items. So my question is can I use the iPhone or iPad charger on the other one?
Is the iPad charger to powerful for the iPhone or is the iPhone charger to weak for the iPad?

To add to the last post: you should not use your iPhone charger with your iPad.

The iPad charger is 10V. Don't give wrong information.
Why not? You can use it but it'll take longer to charge the iPad since its only 5V. The iPad charger is 10V. Don't give wrong information. I've interchanged the chargers since iPad OG.
Is there any worries for the reverse, using the iPad charger to charge the iPhone? I've done it a few times in the past, and it charged it to 100% insanely fast, but it also got quite hot while doing it.

If you are a frequent traveler you should have something like this.I travel a lot and don't like to carry duplicate items. So my question is can I use the iPhone or iPad charger on the other one?

Not sure why you're experiencing that, my iPhone 4s is charging now with the iPad charger and it's not hot at all.
It should not get "quite hot". Warm is good but HOT?
I have used my iPad charger for my iPhones for years.
They have the same connector and Apple kind of thought this all out for us cause they know we will do it.
So which is it?
Here it is, as long as the voltage is similar, the amps do not matter. For example, if a device accepts 5v and you feed it 8v - it's done.
When it comes to amps having the minimum and up is recommended. Your device will typically only draw the amps it needs.
So if you use the ipad charger (~2.1amps) on the iphone (~1amp) - it's fine, as the iphone will only draw the 1 amp it needs.
Think of it in terms of computer power supplies. A computer that requires 500 watts of power for every peripheral to run do fine using a 750W power supply. Watts = Amps x Volts
The #1 reason they supply the appropriate amperage power adapter is to improve efficiency and reduce size. A 1 amp charger will be smaller and more efficient than supplying a 2 amp for a device than only needs 1 amp.
Many thanks for taking the time to type that out. I was sure Amps didn't matter but forgot what did matter (volts). Wish I had eidetic memory.
Maybe I should have described it as warm/quite warm. It was with my iPhone 4 a year ago, using an iPhone 4S now.
Haven't had a need to use the iPad charger, but more I was wondering if there's any damage that can happen when charging with with higher output of the 10W charger.

The iPad USB Power Adapter is a 10W charger. While designed for use with the iPad, you can use the iPad 10W USB Power Adapter to charge all iPhone and iPod models by connecting them using a Dock Connector to USB cable.
Thanks, makes sense.
In theory then, using the 2.1 amp charger and the phone drawing 1 amp, it should charge in the same amount of time as if it was using a 1 amp charger right? I only ask as it seems like the iPhone when used with the 2.1 amp charger charges much faster. Maybe it's capable of drawing more than 1
Thanks for all of the info everyone. I read about charging the iPad on apples website and it sounds like I can still use an older iPhone cable plugged into a computer using a newer usb 2.0 connection to charge the iPad.
Anyone use older iPhone or iPod cables for the iPad and a computer?
Most computer USB ports I have used only deliver 500mA max, which is way bellow the 2.1A required by an iPad. That would take 8+ hours to charge the original ipad at that rate. My original ipad stated that it was not charging whenever I plugged it into a PC. The latest ipad's battery is double the capacity.
