AM5 Power Port Confusion

I have the ZWO AM5 Mount, and I'm a little confused about the 12v Power Ports.

There is one 12v Power Port on the front (next to USB and Hand Conroller ports) that is Labeled 5A.

There is one 12v Power Port on the left side (as you are facing the mount) that is labeled 3A.

The User manual clearly states that the input power is the one on the front, and the output power is the one on the left side.

However, it also states that the input power is >3A and the output power is <5A.

Additionally, in the picture in the user manual, the front port is labeled 3A. Mine is labeled 4A.

In the manual, the left side port is labeled 3A, and mine is not labeled with amps.

So my questions are:
1) Which one is the correct input port?
2) What is the actual output Amps?

Thanks

Input - the one at the front and the rating is 12V 5A
Output - the one on the side - 12V 3A
