RE: Ok

The more reason you should increase output on power supply host to prevent such issue from happening.

Somehow I'm thinking that deliberately overheating a device beyond its design criteria is not a good idea.

However, with LPS-1 having 1.1A current limit, I don't feel safe to power device requiring 1A continuous current even if developer said it's OK.

Given it has 60 farads of storage, I don't share you concern.

it can't even power JCAT USB Card with a single USB hard drive from Seagate

I think you'll find it was never intended to do that. If you return to my previous link, the intended uses don't include spinning rust drives. SSDs, yes.

I interpreted this as using overkill power supply can make uRendu shutting down because it draws too much current.

Perhaps I wasn't clear. Just to suggest such is unnecessary. We had a side topic going on about the possibility of at attached USB device drawing more current than the rendu is comfortable with, i.e. not burn itself up.

Also, universal energized power supply is switching AC>DC using low impedance capacitor for additional $15. If you're familiar with two-step regulation, you can use Nikola for the first step and LPS-1 for the second step.

I'm thinking you don't understand how the two interact. The clever approach to which I previously referred is that the quality of energizer itself doesn't affect the resulting noise output by the supercaps feeding the device.

Sure, you could throw money away, but that would not be my choice.
