So this comes with two power outs for 2 ribbon buses with 14 power parking spaces for your modules. I've had no issues with power. From the operational perspective, I don't think about it at all, it just runs the rack.
I've had good success using a Bosch GAA18V-24 to supply power to the CP1A - so that's been a useful solution for small & portable power (total run time of the kit will vary when running off a battery).
It does not have a lot of features (does it need any?) it's pretty basic. It came packaged really well. As far as I can tell, it does exactly what Behringer claims it's supposed to do.
