USB 1.0 or USB 2 port.0, capable of delivering up to 0.5A. MacBook Pro and MacBook Air versions older than 2012 are equipped with USB 3.0 ports that are capable of delivering 0.9A. However, all iPhones and iPads come with a charger capable of delivering 1A, so it's best to plug your iPhone into a dedicated charger rather than into a USB port.
Note that the exception is the USB C port of the new 12-inch Retina MacBook, which supports up to 3A.

The iPad charger provides 2.1A (12W), which charges the iPhone much faster than the 1A (5W) iPhone charger.
Interestingly, tests using Kill-A-Wattdevice and OS X system showed that the profiles of the iPhone 6 and iPhone 6 plus are the same as the iPad. So you can charge them using a 2.1A charger. Unlike the iPhone 5s and older models, which were only capable of pulling 5W, the iPhone 6 and iPhone 6 Plus are capable of using up to 12W, allowing them to charge faster.
iPhone 6 Plus can be fully chargedin about 2 hours 30 minutes using the iPad charger, while the process takes 3 hours 45 minutes if charged using the charger that came with your iPhone.
Use Apple's Lightning USB cable to charge
To achieve best results, it is advisableUse the Lightning USB cable and charger that came with your iPhone or that is certified by Apple. The wrong cable or charger can slow down charging speed.
In some cases, counterfeit chargersthe devices only provide half the power. This means it will take twice as long to fully charge your iPhone. There are many other reasons why you shouldn't use counterfeit chargers.
