Unless the s4 charging port has changed (doubt it) it'll work. Heck dang near any charger will work for it.
That looks like the stock oem charger Samsung phones come with.

Since the phone comes with a 2A charger I don't see how a 2A charger would be a problem. As mentioned, voltages is like the pressure pushing the current into the device, amps is like the size of the pipe carrying the current (bigger the pipe the more that can flow up to the amount the device wants).
I've noticed most of my spare chargers are only .75Amps. And it does take a long time to charge vs the one that came with my S4, especially when I plug into my lap top, seems like it barely charges at all.
Can't wait for the new USB 3.0, or should I say... USB 3.5 standard. Apparently, the speed will increase from 5 Gbps to 10 Gbps and capable of delivering 100 Watts of power. Intel Developer Forum showcased the new USB 3.5 standard in which they had a full desktop LCD monitor and an external HDD all running off of the USB 3.5 port without unsightly external power adapters.
Can you imagine? Plug your phone in and in less than 45 minutes have your phone fully charged off of your notebook.
