    Will it damage the iPhone??? Or will the iPhone only draw what it requires? I don't think it's USB-c capable anyway....

    I'm travelling soon and have the 29 watt charger and lightning to USB-c cable for my iPad Pro 12.9. And to save bringing multiple chargers I want to just bring the one charger. I tried it last night on the iPhone and it charged no problem and was not even hot or anything so is it safe?

    It won't. The iPhone only draws what it needs. In fact, it will charge your iPhone faster than the charger it came with. General rule is that you can use a higher capacity charger but you can go below the original capacity charger EX: Can't use iPhone charger to charge iPad but you can use iPad charger which is higher capacity on your iPhone.

    What's important to remember about the chargers is what Voltage they output, not the max current they output or the power, as long as the unit doesn't draw more power than the charger can output. Devices will always draw the current they need. No more and no less.

    If I have iPad in sleep I use the iPhone charger overnight. Charges iPad fine, just takes longer.

    The iPhone 6s is limited to 2100 mw at 5v charge
    You are required to install OS X El Capitan to be able to charge iPhone at this level using your computers USB ports

    If you're running OS X Yosemite , then you only get 1000mw

    The SE is still limited to 1000 mw

    Not quite. Any charger can charge any device. If you use a higher capacity charger, the device will draw what it needs. If you use a lower capacity charger, the device will only pull up to what the charger can output.

    If you use a 5W charger on the 12.9" iPad Pro, it will take a LONG time to charge!

    The explain why my iPad 1st generation would always say "Not Charging" when plugging into a small charger or my computer. Sometimes it still works but it's generally not advised to do that

    It will work fine, just will take longer. Not advised perhaps from the point of view that it would take noticeably longer but not because it won't work or is bad in some way.
