>> Most USB Ports on computers are limited to 500mAh.
>> The supplied wall wart for an iPhone 4 is 1000mAh or 1Ah.
>> The supplied wall wart for an iPad is 2000mAh or 2Ah.
>> The iphone should regulate its self to 1000mAh max current draw when charging. SO if your using a charger that produces more current then its needing the phone will limit its self to prevent it from charging to fast and over heating.

I was hoping that someone would correct his mis-statement.
However, I was also hoping that the correction would be correct.

In both cases above, we should be referring to 500 or 1000 mA.
NOT mAh.
The battery capacity may be rated in milli-amp-hours, but the charger is rated in milli-amps at the rated voltage.
