What USB port is Fast Charging? ?

Question

Im going to get a USB car charger (you know the ones that you stick in the cigarette lighter of your car), and am not sure about which one to get. I want one that has fast charging for S10 and has like 2 USB ports in it (preferably o being USB-C), but I'v seen some that have different voltages and Im unsure of which one would fit what Im looking for. I'v seen 2.1A and 1.0A and others with QC3.0. Im sure there are others that I havent seen. So which one would allow me to have fast charging?

Quick Charge 3.0 is 4x faster than conventional charging (USB1.0). USB 2.1A is going to be faster than 1.0A. QC3.0 is 2x as fast as Quick Charge 1.0 and to be 38 percent more efficient than Quick Charge 2.0.

if it has USB-C and says fast charging, then it should work.
like this:

notice the wattage...
keep in mind that charging speed will slow if you try to charge more than one phone at a time.

2.1 is called fast charge because at the time, it was the fastest you can get. It’s more than twice as fast as 1.0A but it’s still not as fast as if you’re using a wall outlet with usb-c.

If you want fast charge, get the 54W usb-c.
