Some observations...
The newly installed rear USB ports will charge my iPad, whereas the factory front USB ports do not, and may not push enough power. So a definite advantage to having these new ones.
Second though, maybe nitpicking and really just exclusive to the
USMEI Dual QC3.0 USB Charger Socket that I bought. If you look closely you'll see that the one port accepts your USB cable right-side up, but the other is upside-down. In other words if you want to disconnect from one and move to the other, you'll need to turn the USB cable over. Sort of an odd design decision but not the end of the world. I'm more happy that the matte black on the charger housing is pretty much an identical match to my Rebel end cap.
