According to a MacRumors forum member, the iPhone 6 and 6 Plus are capable of faster charging by using an iPad charging adapter, instead of the standard 1A/5W block found in the box. The iPad 2.1A/12W charger draws 12W as oppose to 5W with the iPhone 6 charger in the box. The folks over a MacRumors used a Kill-A-Watt device to measure the outputs and claim that using the iPad charging adapter can charge an iPhone 6 Plus fully in about 2 hours.
