The short answer is that if your USB power source is capable of pumping the current into one of these devices, they will accept it.

The S5 is powered down during this test (obviously the internal smart-charge circuit is not powered down). My S5 is drawing 1.79 A from the standard USB wall charger and standard (2.0) USB cable. I measured the voltage and current coming from my USB power source (more on that later) and used a relatively new Galaxy S4, and an S5, as my test units. Lots of people say "should" and "might" and "generally" but there is no actual answer. I've been trying to find an answer to the question at the top of this page, and so far have not found anyone who has actually measured things. Or if you must, charge with USB but it will be much slower than a dedicated charger. Use your USB 3.0 ports for USB 3.0 devices and buy a charger for your phone. Theoretically this could charge at 950mA but I haven't seen anything to confirm it. I can't say for sure about the Galaxy Note 3, however, as it is the only device with an actual USB 3.0 interface. Without this, most phones will simply charge at 500mA regardless of the USB flavor you choose. Some phones can use a modified kernel that allows you to tell the phone to ignore the 500mA limit on USB.

It is not uncommon for USB ports to support 1A or higher though, especially on laptops. The official standard sets USB 2.0 current levels at 500mA and 3.0 at 950mA. Most phones will only charge at 500mA (about half of what a DC charger for a modern smartphone outputs) if it detects it is a USB port.
