How many amps is my charger (pics).

I just bought a charger with 2 usb ports. The back of it says the output is 2.4 amps.

Is each Port 2.4 amps. Or is the first Port 1.2 amps and the second Port 2.1 amps (divides them in half?).

Just wondering because my phone originally came with a 2.1 amp charger and I lost it. I want to make sure this one has enough power.
