I'm puzzled. I am deciding between the PowerDrive Speed 2 and the PowerDrive+ 2 for my mom and dad to charge their LG G4s. The G4 supports QC 2.0, but they would like a charger compatible with 3.0 for their next phones (probably the V20) in a year or two down the road.
I see that the Speed 2 has 2 QC 3.0 ports, and outputs 39W. The + 2 has one QC 2.0 port and one QC 3.0 port, but for some reason, it is 42W. It seems like the Speed 2 is superior in all ways except for the wattage. Does anyone have an explanation? And which one would you recommend?
