Throughout my testing the charger had no problem charging a QC 3.0 and QC 2.0 device simultaneously. I also tested the charger on some older devices that only require 1A to charge and it worked perfectly. Having one charger that can charge two devices with the latest charging technologies at the same time is very convenient. While I do wish it were a little smaller, it is not large enough to really be of concern.
