As far as I can tell, there's no such thing as "conventional 2.4A USB charging". The USB 2 spec limits power output to 5v, 900 mA. USB 3 has the Battery Charging Specification that allows up to 1.5 A. I think you might be thinking of Qualcomm Quick Charge?

- ianburrell 8y agoThe USB Battery Charging spec is separate from USB3. The 1.5A is the minimum available current for charging port; the max is 5A. But the limit for legacy USB cables is 2.4A.
