## Questions & Answers

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

**Q: Can one use this to “trickle “ charge a motorcycle battery?**
A: 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.

**Q: Does the usb in ports support data pass through to the usb out ports?**
A: Not supported, it is a power converter and does not support data communication

**Q: Does this display delivered current in real time?**
A: With multiple sets of fading LEDs, I'm observing about 2 current updates per second
