Can this can take an input of 5v 2.1a and output 30v 2.5a, and is the set output stable?

No, not unless I have overlooked what would be a very valuable feature. If we assume 100% efficiency for conversion, 2.1 Amps at 5 Volts would give you only 0.35 Amps at 30 Volts, more realistically it would be much less than that since the conversion will not be 100% efficient . 30V * 2.5A= 75 Watts, 5V * 2.1A = 10.5Watts I hope this helps. Please forgive me if I have misunderstood the question.

Can one use this to “trickle “ charge a motorcycle battery?

The previous answer is incorrect. Yes, it absolutely would. In fact, its current handling capacity (~1A or so) would be more than enough to charge a motorcycle battery (12-24 hours), let alone maintain it. However, since it isn't programmable, you wouldn't get the benefit of occasional absorption cycles to prevent sulfation. Nevertheless, you could winter float a 300Ah 8D with this thing with no issues.

Does the usb in ports support data pass through to the usb out ports?

Not supported, it is a power converter and does not support data communication

Does this display delivered current in real time?

With multiple sets of fading LEDs, I'm observing about 2 current updates per second
