I thought 120VAC was standard for power outlets pretty much through all of the US. Surely that's so in Texas!

I just did a test with my iPad Air 2 and iPhone 6 plus. The iPad was at 64% and 15 minutes later it was at 72%. The iPhone 6 Plus, as you may know can charge from a 2.1amp charger at a faster rate than from a 1.1amp. Was at 83% and ended at 93% after the 15 minutes. Both were plugged into the same USB 120(volt) outlet at the same time.
This may or may not be helpful information as it was not compared to the same portion of a charging cycle using an Apple charger.
For instance, the iPad increased 8% in charge in a quarter hour. Without further information as to linearity of the charge, that translates to a full charge from dead in about three hours. The iPhone 6+ increased 10% in 15 minutes, implying 2 1/4 hours to charge from dead.
Of course, there's nothing to make us believe that a charge from dead is a linear process, so those figures are of unknown value.
It's been well publicized that Apple has built into their charger/phone combinations some proprietary circuitry that turns on fast charging only when an Apple charger is used, so it's necessary to test against an Apple charger to understand if these are fast charge rates.
It does not feel warm to the touch. So the generated heat maybe inside or it keeps cooler than other 2.1amp chargers.
The heat thrown off in the process of going from 120volts to 5 volts goes somewhere! Is that outlet on an outer wall of your house, and it's 22 degrees outside? Or....
