Bottom line is that all USB type A Quick Charge 3.0 ports are very likely to handle a maximum 2.6 Amp unless they fall back to not using Quick Charge at all. So if you’re only interested in the Quick Charge capabilities then there’s no difference between the 2.4A and 3A chargers.
Is 2.4 A fast charge?
The same mobile phone with a 2.4A charger will take 1.25 hours to charge. All this assuming a 100% efficiency, which is not real: usually efficiency is around 80% or 70%, so the times will be slightly higher. In other words, the 2.4A charger is 58% faster than the 1A charger, a remarkable difference.

QC 3.0 Basics
QC 3.0 is similar to PD 3.0 in that it offers better charging performance than standard USB. Also like PD 3.0, both the charger and the device must be compatible with QC 3.0 for it to work. If your phone supports QC 3.0 but your charger doesn’t, you won’t gain any benefit.
Does QC 3.0 require special cable?
Do I need a special cable to fully receive speed benefits of quick charge 3.0? – Quora. Nope. Quick Charge 3.0 is designed specifically to work with the same ~2.0A limits imposed by standard, everyday USB 2.0 cables. Quick Charge 3.0 is limited to 18W peak charging, just as Quick Charge 2.0.
Is 5V 2.4 A fast charging?
Most phones and other devices are capable of handling 5V/2.4A. For fast charging, you’re looking at something that bumps the voltage up 5V, 9V, 12V, and beyond, or increases amperage to 3A and above.
Does QC 3.0 work with iPhone?
Qualcomm Quick Charge 3.0: This is a fast-charge technology that is able to help a wall adapter charge a device up to 4x times faster than the conventional 5W charger. But iPhones don’t support this technology, so it’s a non-issue for iPhone owners.
What charges faster 2.4 A or 1A?
If it’s limited to 1A, it won’t draw more than 1A, even if the charger is capable of 10,000A. The S4 should draw about 2.1A max, so a 2A charger will take a few minutes longer to charge it. A 2.4A charger will be supplying 2.1A, so a.
Is 2.4 A good for A charger?
Generally, the more power the USB port provides, the faster the charge. So, if you need to charge your device quickly, choose a charging station with high-speed ports (2.4A or 5A).
Does usb3 charge faster?
USB 2.0 vs 3.0: Charging and Power
A USB 2.0 port is able to deliver 0.5 A of power while USB 3.0 is able to output 0.9 A. This means two things: USB 3.0 devices are able to charge faster and USB 3.0 ports can support more power-hungry devices.

Will a 3 amp charger hurt my phone?
Nothing, because nothing is there to ask for the amperage needed to produce that kind of power. It goes to a step down converter usually to 5 volts at 2 amps. Fast charging is 9 volts at about 1.7 amps. I would not recommend plugging your phone into a standard home 110 outlet.
What determines charging speed?
When charging a phone, a certain amount of current flows from the power source, through the charger, to the phone or other connected devices. Since the charger determines the current and the voltage, it determines the maximum output power and thus the charging speed.
How many watts is fast charging Samsung?
