Jul 16, 2012 4:16 PM in response to HasanMoukalledby Lawrence Finch,How high a voltage? The standard Apple charger will work with input voltage up to 240 volts. I don't think you can find higher than that anywhere in the world.

Why would you do that? The power adapter has protective circuits at both the input and output. If you attached 260VAC to the input, it is likely to shut down, and can be reset by unplugging the power adapter, and plugging it into an AC outlet with the proper voltage. I'm sure you have plenty of follow-on questions ("how about 400VAC, 2000VAC, a million billion trillion volts AC), and I won't entertain those.

Mar 22, 2016 11:54 AM in response to Lawrence Finchby mrlawrencelam,You wrote an article at Everything you wanted to know about charging your iPhone or iPad . Theoretically this is a great article and I know many people in internet thank you for your explanation. Unfortunately you missed out something - the facts!
You said:
If it takes your iPad charger (2.1A) 5 hours to charge up your iPad with the iPhone charger (1.0A) it will take 10 hours to charge it because it is about 1/2 the watts and amps.
I did a lab test using a current meter and it showed that you were wrong about the statement above.
When you charge an iPad Air with an iPad charger (2.1A), the current flowing into the iPad is NOT 2.1A. You will get not more than 1.6A when your iPad's battery is almost flat to half full. But you assumed that the current is 2.1A. The iPad charger is just a transformer and techinically it shouldn't be called a charger. The actual charger is residing in your iPhone/iPad and it is the one that is regulating the power. I do not know why, but the iPad Air is only allowing less than 1.6A entering it (and not 2.1A).
