Amperage is NOT something that is "pushed" by the adapter/power supply. Its voltage that is "pushed".
The amperage rating is a maximum load specification. The attached device, in this case a K3, pulls or "draws" current (measured in Amps). If the device draws too much the adapter can be damaged, not the device.
The spec's listed by the OP are incomplete, though they may be all that is listed on the device. A proper set of specs will list the input values, voltage range tolerated and current drawn (amps), and the output values. The input amperage actually varies in this type of adapter depending on what is being drawn by the device attached to it. The input amperage rating is the expected maximum. The output values are the voltage "pushed" out by the device and the maximum load (amps) it can tolerate.
Any such adapter that properly replicates the industry standard USB output values should work safely with a K3. Its possible that the K3 will charge slower on an adapter limited to the standard USB current levels than it does on its own adapter. I don't know about the K3 specifically, but I have seen devices that list different charge times for their dedicated adapter and USB charging.
